  • Psychosocial Predictors of Drop-Out from Organised Sport : A Prospective Study in Adolescent Soccer
  • 2022
  • Ingår i: International Journal of Environmental Research and Public Health. - Basel : MDPI. - 1661-7827 .- 1660-4601. ; 19:24

    • In recent years an increased drop-out rate in adolescents' soccer participation has been observed. Given the potentially adverse consequences of drop-out from soccer, more information about risk factors for drop-out is warranted. In the current study, Classification and Regression Tree (CRT) analysis was used to investigate demographic and motivational factors associated with an increased risk of drop-out from adolescent soccer. The results of this study indicate that older age, experiencing less autonomy support from the coach, less intrinsic motivation, being female, and lower socioeconomic status are factors associated with an increased risk of drop-out. An interpretation of the results of this study is that coaches play a central part in creating a sports context that facilitates motivation and continued soccer participation. Based on the findings of the current study we propose that soccer clubs implement theoretically informed coach education programs to help coaches adopt autonomy-supportive coaching strategies.

  • Exploring psychosocial risk factors for dropout in adolescent female soccer
  • 2022
  • Ingår i: Science and medicine in football. - Oxfordshire : Routledge. - 2473-3938 .- 2473-4446. ; 6:5, s. 668-674

    • Objectives: We examined the manner in which age, participation in other sports, socioeconomic status, perceived sport competence, achievement goal orientations, and perceived motivational climate may interact to predict the risk of dropout among adolescent female soccer players.Methods: Self-reported data from 519 female soccer players between 10 and 19 years of age (M = 13.41, SD = 1.77) were analysed using a person-centred approach to uncover the interactions among risk factors and their relative predictability of dropout.Results: Perceived motivational climate was identified as the main predictor, where relatively lower levels of mastery climate were associated with a higher dropout tendency (absolute risk reduction [ARR] = 12.2% ±6.1% [95% CL]). If combined with relatively lower levels of mastery climate, then relatively lower levels of perceived sport competence were related to higher dropout risks (ARR = 16.5% ±9.5%), whereas, in combination with relatively higher levels of mastery climate, then relatively lower levels of ego-orientated achievement goals were associated with higher dropout rates (ARR = 10.8% ±12.6%).Conclusions: Our findings afford novel insights into the interactions between, and the relative importance of, various risk factors for dropout in adolescent female soccer. This knowledge may be useful for soccer associations, clubs, and coaches when developing guidelines and strategies that aim to foster young females’ sustained participation in organised soccer.

    • During the last decades, an increased drop-out rate in adolescents’ team sport participation is observed. Given the potential adverse consequences of drop-out from team sport more information about risk factors for drop-out is warranted. The objectives of this systematic review were to (1) synthesise the literature on factors associated with future drop-out from team sport among adolescents and (2) investigate the strength of associations between drop-out and related factors with meta-analysis. The databases Academic Search Elite, ERIC, PsycINFO, PubMed and SPORTDiscus were searched for relevant publications from the earliest reported date until October 8, 2021. Articles were included if: (1) data about drop-out was collected; (2) the focus was on adolescents; (3) the context was team sport and (4) studies were of prospective design. We used the Risk of Bias Assessment Tool for Non-randomized Studies (RoBANS) to assess the risk of bias in included studies. A narrative synthesis was conducted according to the reporting guideline of synthesis without meta-analysis. Studies that presented statistical data necessary for the calculation of Hedge’s g effect sizes were included in the meta-analysis. In total, 16 studies met the inclusion criteria and were included in the narrative synthesis. The meta-analysis included 12 of the studies. Altogether, 6304 adolescent team sport players participated in the selected studies. Of those studies, most had a focus on intrapersonal factors relationship with drop-out. The results showed that constructs related to motivation as well as sport experience had the strongest relationships with drop-out. To prevent drop-out from adolescents’ team sport, organisations and clubs are recommended to focus on developing a high-quality motivation climate that facilitates motivation and enjoyment. © 2022 The Authors

  • Psychological risk factors for exercise dependence
  • 2021
  • Ingår i: International Journal of Sport and Exercise Psychology. - New York : Routledge. - 1612-197X .- 1557-251X. ; 19:4, s. 461-472
  • Tidskriftsartikel (refereegranskat)abstract
    • The main aim of this study was to investigate if exercisers' personality characteristics were associated with exercise dependence. Specifically, the purpose was to examine if anxiety, obsessive passion, and physical appearance orientation were associated to an increased risk for exercise dependence. Participants were 330 exercisers from exercise groups, sport clubs and university sport science classes in the southwest of Sweden. Data were analysed using CHAID (Chi-squared Automatic Interaction Detection) analysis. The CHAID analysis indicated that anxiety was the main predictor of exercise dependence. More specifically, 12.7% more exercisers who experienced high levels of anxiety symptoms (i.e. scores above 6), were, in comparison to the exercises experiencing low levels of anxiety, classified as ?at risk for exercise dependence?. For exercisers that reported low levels of anxiety symptoms (i.e. scores below 7), obsessive passion for exercise was a positive statistically significant predictor (absolute risk difference?=?8.6%). Overall, the results highlight anxiety as a main risk factor behind exercise dependence. Also, the risk of exercise dependence may increase either from obsessive passion or as a coping strategy for anxiety. Furthermore, results may illustrate two types of exercise dependence; ?primary? exercise dependence driven mainly by an obsessive passion for exercise and ?secondary? exercise dependence where exercise function as a strategy to cope with anxiety.

  • Psychosocial risk factors for dropout from adolescents’ soccer
  • 2023
  • Konferensbidrag (refereegranskat)abstract
    • Background: The number of adolescents that drop out of soccer has increased the last decades. As soccer participation may represent a substantial part of adolescents’ physical activity, efforts to reduce drop-out are important. To develop effective prevention programs, knowledge about why adolescents drop out is needed.Purpose of the study: Using a prospective design, over three consecutive seasons, we investigate differences in motivation and coach autonomy support between adolescents that stay in soccer and adolescents that drop out.Methods: Participants were 738 adolescents (462 males and 275 females), 11-17 years old (M = 13.72, SD = 1.77) from soccer clubs in Sweden. Data about demographics, motivational regulations and coach autonomy support was collected in 2019, drop-out data at the end of seasons in 2019-2021. We used Mann-Whitney u-test to analyse potential differences between the two groups. A p-value <.05 was considered a statistically significant result. Cohen’s d effect size was calculated for each comparison.Findings: Of the participants, 256 (34,7%) dropped out until the end of the 2021 season. Dropouts experienced lower intrinsic motivation (U=55263, N1=479, N2=253, p=.006, d=0,15), more amotivation (U=66358, N1=482, N2=256, p=.042, d=0,13) and less coach autonomy support (U=49566, N1=479, N2=253, p=<.001, d=0,30). Regarding identified motivation (U=57329, N1=482, N2=255, p=.13, d=0,11) and introjected motivation (U=64628, N1=482, N2=256, p=.25, d=0,08) no statistically significant differences were found.Conclusion: To facilitate motivation and continued soccer participation we propose theoretically informed education programs to help coaches adopt autonomy-supportive coaching strategies.

  • High-level military and sport leaders' everyday challenges and psychological skills : A cross-contextual repeated measures study
  • 2024
  • Ingår i: Military Psychology. - Washington, DC : Routledge. - 0899-5605 .- 1532-7876.
  • Tidskriftsartikel (refereegranskat)abstract
    • Research shows that high-level military and sport leaders share a high-stress and high-stakes leader role due to similar experiences of demanding conditions mainly manifested in psychological burden. This raises research questions about leaders' psychological strategies to maintain their mental health and performance under demanding conditions. Thus, the current study investigated how experienced demanding conditions were related to self-rated leader performance level and mental health indicators among high-level military and sport leaders and whether the application of psychological skills by these leaders moderated these relationships. A composite questionnaire was used to collect data longitudinally, once a week for four consecutive weeks. Fifty-two Swedish high-ranking military officers and executives in elite team sport organizations completed the questionnaire. Multilevel analysis revealed no effect of demanding conditions on leader performance, but they harmed leader vitality and were associated with higher stress symptoms. Moreover, psychological skills did not moderate the relationship between demanding conditions and leader performance. However, motivational and instructional self-talk negatively moderated the relationship between demanding conditions and vitality. In contrast, emotional regulation, comprised of mindfulness and cognitive reappraisal, positively moderated vitality. Emphasizing the nuanced application of psychological skills is crucial while avoiding one-sided beliefs about their positive effects. Interventions are suggested to focus on vitality and related psychological skills to ensure leaders feel good while performing under demanding conditions. More cross-contextual leadership research, suggestively applied research, is needed to better understand the links between high-level military and sport leaders' psychological skills, leader performance, and mental health under demanding conditions. © 2024 The Author(s).

  • The effects of interpersonal development programmes with sport coaches and parents on youth athlete outcomes : a systematic review and meta-analysis
  • 2024
  • Ingår i: Psychology of Sport And Exercise. - Amsterdam : Elsevier. - 1469-0292 .- 1878-5476. ; 70
  • Forskningsöversikt (refereegranskat)abstract
    • Interpersonal coach-and parent development programmes (CDP and PDP, respectively), have the goal to foster positive youth sport experiences through high-quality relations between coaches, parents, and youth athletes. In this paper we systematically reviewed the extant literature and estimate the overall magnitude of such programmes and how they can inform future interventions. Specifically, we aimed to: (a) conduct a systematic review on the literature of interpersonal CDPs and PDPs within the youth sport context; (b) examine the effects of such interventions on youth athlete outcomes via a meta-analysis. English written peer-reviewed publications and grey literature was identified through electronic search in databases and manual searches of reference lists. By utilising a priori criteria for inclusion and exclusion, 33 studies describing interpersonal CDPs, and PDPs were identified in the systematic review. Studies that presented required data for estimation of Hedge's g effect sizes were included in the meta-analysis (k = 27). By and large, the included studies used a quasi-experimental design (58%), sampled from team sports (79%), and reported several delivery methods (e.g., workshops, audio feedback, observations, peer group discussions) and outcome measures (e.g., anxiety, autonomous motivation, self-confidence). Some interventions were based on the same delivery protocols (e.g., Coach Effectiveness Training, Mastery Approach to Coaching) or theoretical frameworks (e.g., Achievement Goal Theory, Self-Determination Theory). The meta-analysis showed statistically significant small, and medium, effect sizes on a subsample of youth athlete outcomes (e.g., task-related climate, fun and enjoyment, anxiety), indicating that coach interpersonal skills can contribute to positive youth sport experiences. Theory-based interpersonal CDPs and PDPs are recommended to expand the knowledge in this field of research.

  • Consistency tendency and the theory of planned behavior : a randomized controlled crossover trial in physical activity
  • 2020
  • Ingår i: Psychology and Health. - Abingdon : Routledge. - 0887-0446 .- 1476-8321. ; 35:6, s. 665-684
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: This study examined the effects of consistency tendency on the predictive power of the theory of planned behavior (TPB) in relation to physical activity behavior.Methods: In this randomized controlled cross-over trial, we recruited 770 undergraduate students from Indonesia who were randomly assigned into two groups. Participants completed physical activity versions of TPB measures at T1 (baseline) and T2 (post 1 week), and the International Physical Activity Questionnaire at T3 (post 1 month). At T1 and T2, the TPB questions were either presented in ensemble-order (i.e., consistency tendency supressed) or alternate-order (i.e., consistency tendency facilitated).Results: The parameter estimates of the model (CFI > .92, TLI > .90, SRMR < .08, RMSEA < .08) aligned with the tenets of TPB. As compared to ensemble-order, a TPB measured in alternate-order yielded stronger cross-sectional relationships, but this pattern did not appear in the prospective relationships in TPB (i.e., intention/perceived behavioral control and behavior).Conclusions: Consistency tendency inflated the factor correlations of cross-sectionally measured TPB variables, but the inflation was not observed in the prospective prediction of behavior. Health psychology questionnaires with items presented in ensemble order may represent a viable means of reducing the confounding effect of consistency tendency. © 2019 Informa UK Limited, trading as Taylor & Francis Group.

    • Consistency tendency is characterized by the propensity for participants responding to subsequent items in asurvey consistent with their responses to previous items. This method effect might contaminate the results ofsport psychology surveys using cross-sectional design. We present a randomized controlled crossover studyexamining the effect of consistency tendency on the motivational pathway (i.e., autonomy support → autonomousmotivation → intention) of self-determination theory in the context of sport injury prevention. Athletesfrom Sweden (N = 341) responded to the survey printed in either low interitem distance (IID; consistencytendency likely) or high IID (consistency tendency suppressed) on two separate occasions, with a one-weekinterim period. Participants were randomly allocated into two groups, and they received the survey of differentIID at each occasion. Bayesian structural equation modeling showed that low IID condition had strongerparameter estimates than high IID condition, but the differences were not statistically significant.

  • Investigating the influence of intra-individual changes in perceived stress symptoms on injury risk in soccer.
  • 2018
  • Ingår i: Scandinavian Journal of Medicine and Science in Sports. - Chichester : John Wiley & Sons. - 0905-7188 .- 1600-0838. ; 28:4, s. 1461-1466

    • Research has shown that high levels of stress and stress responsivity can increase the risk of injuries. However, most of the research that has supported this notion has focused on between-person relationships, ignoring the relationships at the within-person level. As a result, the objective of this study was to investigate if within-person changes in perceived stress symptoms over a one-month time period could predict injury rates during the subsequent three months. A prospective design with two measurement points (Time 1 - at the beginning of the season and Time 2 - one month into the season) was utilized. A total of 121 competitive soccer players (85 males and 36 females; Mage = 18.39, SD = 3.08) from Sweden and the United States completed the Kessler Psychological Distress Scale (KPDS) and a demographic sheet at Time 1. The KPDS was also completed at Time 2 and all acute injuries that occurred during the subsequent three-month period were recorded. A Bayesian latent change scores model was used to determine if within-person changes in stress symptoms could predict the risk of injury. Results revealed that there was a credible positive effect of changes in stress symptoms on injury rates, indicating that an increase in reported stress symptoms was related to an increased risk for injury. This finding highlights the importance of creating caring and supportive sporting environments and relationships and teaching stress management techniques, especially during the earlier portion of competitive seasons, to possibly reduce the occurrence of injuries.

  • Profiles of psychosocial factors : Can they be used to predict injury risk?
  • 2022
  • Ingår i: Scandinavian Journal of Medicine and Science in Sports. - Chichester : John Wiley & Sons. - 0905-7188 .- 1600-0838. ; 32:4, s. 782-788

    • The creation of risk profiles using the model of stress and athletic injury (J Appl Sport Psychol. 1998;10(1):5) represents a proposed shift from the reductionism paradigm to the complex sport approach in an attempt to formulate prevention strategies to combat the increasing number of injuries being reported in sporting populations. As a result, the primary purpose of this study was to: (a) identify different risk profiles based on psychosocial factors associated with the Williams and Andersen's model of stress and athletic injury model; and (b) examine potential differences in the frequency of injuries across these risk profiles. A prospective research design was utilized with a sample of 117 competitive soccer players (81 males and 36 females) from Sweden and the United States of America. Data was collected at two time points over the course of three months. At time 1 (beginning of the season) - a demographic information sheet, the Life Event Survey for Collegiate Athletes (LESCA), Sport Competitive Anxiety Test (SCAT), and Brief Cope were administered. At time two (T2), three months after the initial data collection, participants' traumatic injuries were recorded. Latent profile analysis (LPA) showed that 3 profiles solution showed best fit to data. Players in profile 1 and 2 reported fewer injuries compared to players in profile 3. However, whereas individuals in profile 1 had a lower predictive risk of sustaining an injury when compared to those in profile 3, both profiles had similar anxiety levels and use of coping strategies with differing stress levels. These findings suggest that the interaction between different proposed risk factors might influence injury risk.

  • Interventions for improving mental health in athletes : a scoping review
  • 2023
  • Ingår i: International Review of Sport and Exercise Psychology. - Oxon : Routledge. - 1750-984X .- 1750-9858.
  • Forskningsöversikt (refereegranskat)abstract
    • The aims of this scoping review were to map the current literature on interventions for improving mental health in athletes, identify knowledge gaps, and generate future research questions. The Preferred Reporting Items for Systematic Review and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guided this review. A systematic literature search was conducted in SPORTDiscus, PsycINFO, and SCOPUS and 44 intervention studies met the inclusion criteria. Results showed that 22 studies (50%) implemented cognitive behavioural principles, and the majority of these studies were influenced by various mindfulness programmes. Most studies (93%) included healthy athlete samples, and athletes aged 15–19 were the most examined age group (43%). Only three studies used clinical criteria in their sampling of participants and mediators were examined in two studies. The scarcity of studies examining mediators and subclinical or clinical samples revealed critical knowledge gaps in the literature. Furthermore, the critical appraisal showed that regardless of study design, most studies demonstrated low internal validity. We propose the use of high-quality single-case studies with athletes who experience subclinical or clinical mental health issues, and further investigation of mechanisms of change linking intervention components to outcomes of interest.

  • Associations between physical activity and core affects within and across days: a daily diary study
  • 2021
  • Ingår i: Psychology & Health. - Abingdon : Informa UK Limited. - 0887-0446 .- 1476-8321. ; 36:1, s. 43-58
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: The objective of the present study was to investigate (a) if daily physical activity at the within-person level is related to four different core affects the same evening, (b) if core affects in the evening predict physical activity the following day, and (c) if physical activity predicts core affects the following day. Design: A total of 166 university students were asked to complete the affect and physical activity measures once a day (in the evening), for seven days. Bivariate unconditional latent curve model analyses with structured residuals were performed to investigate the relations within days and across days between the core affects and physical activity. Main outcome measures: Core affects and physical activity. Results: Physical activity had positive within-day associations with pleasant-activated and pleasant-deactivated core affects and a negative within-day association with unpleasant-deactivated affective responses. There were, however, no statistically significant relations between core affects and physical activity across days. Conclusion: These results highlight that the measurement interval might be an important factor that influences the association between core affects and physical activity behaviors.

  • Negative psychological responses of injury and rehabilitation adherence effects on return to play in competitive athletes : a systematic review and meta-analysis.
  • 2017
  • Ingår i: Open Access Journal of Sports Medicine. - Macclesfield : Dove Medical Press Ltd. (Dovepress). - 1179-1543. ; 8, s. 27-32
  • Forskningsöversikt (refereegranskat)abstract
    • Previous research offers evidence that psychological factors influence an injured athlete during the rehabilitation process. Our first objective was to conduct a systematic review and meta-analysis of the results from all published studies that examined the relationships among negative affective responses after sport injuries, rehabilitation adherence, and return to play (RTP). The second objective was to use a meta-analytic path analysis to investigate whether an indirect effect existed between negative affective responses and RTP through rehabilitation adherence. This literature review resulted in seven studies providing 14 effect sizes. The results from the meta-analysis showed that negative affective responses had a negative effect on successful RTP, whereas rehabilitation adherence had a positive effect on RTP. The results from the meta-analytic path analysis showed a weak and nonsignificant indirect effect of negative affective responses on RTP via rehabilitation adherence. These results underline the importance of providing supportive environments for injured athletes to increase the chances of successful RTP via a decrease in negative affective responses and increase in rehabilitation adherence.

  • Bokkapitel (refereegranskat)abstract
    • Sport injuries are a major problem associated with sport participation. To develop preventive strategies and programs, it is important to identify factors that will increase the likelihood of sport injuries. In most sport injury risk factor research, statistical analyses are performed; however, many of the most common statistical analyses provide limited information about predictors of sport injury risk. The common analyses used in previous studies do not acknowledge the complexity associated with investigating risk factors for sport injuries. To better capture this complexity, suggested in most theoretical frameworks, more appropriate of statistical approaches should be used. In this article we present how latent profile analysis, latent change score analysis, and latent growth curve analysis can be used to overcome some of the limitations with more traditional analyses. Lastly, we also elaborate on future directions for analyses in sport injury risk factor research. More specifically, we present how advanced statistical models, such as classification and regression trees (CART) analysis and random forest analysis, can be used to provide researchers and clinicians with results that are more clinically meaningful.

  • Psychosocial factors and sport injuries: Meta-analyses for prediction and prevention
  • 2017
  • Ingår i: Sports Medicine. - Auckland : Springer Science and Business Media LLC. - 0112-1642 .- 1179-2035. ; 47:2, s. 353-365
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Several studies have suggested that psychosocial variables can increase the risk of becoming injured during sport participation. Objectives The main objectives of these meta-analyses were to examine (i) the effect sizes of relationships between the psychosocial variables (suggested as injury predictors in the model of stress and athletic injury) and injury rates, and (ii) the effects of psychological interventions aimed at reducing injury occurrence (prevention). Methods Electronic databases as well as specific sport and exercise psychology journals were searched. The literature review resulted in 48 published studies containing 161 effect sizes for injury prediction and seven effect sizes for injury prevention. Results The results showed that stress responses (r = 0.27, 80 % CI [0.20, 0.33]) and history of stressors (r = 0.13, 80 % CI [0.11, 0.15]) had the strongest associations with injury rates. Also, the results from the path analysis showed that the stress response mediated the relationship between history of stressors and injury rates. For injury prevention studies, all studies included (N = 7) showed decreased injury rates in the treatment groups compared to control groups. Conclusion The results support the model’s suggestion that psychosocial variables, as well as psychologically, based interventions, can influence injury risk among athletes.

  • The predictive ability of the talent development environment on youth elite football players' well-being : a person-centered approach
  • 2015
  • Ingår i: Psychology of Sport And Exercise. - Amsterdam : Elsevier. - 1469-0292 .- 1878-5476. ; 16:1, s. 15-23

    • Objective: The objective of this study was to examine the predictive ability of perceived talent development environment (TDE) on the well-being of youth elite football players.Design: A field-based longitudinal design was employed.Method: The participants were 195 Swedish youth elite football players between 13 and 16 years of age enrolled at Swedish football academies. The players responded to questionnaires regarding their perceptions of their TDE, perceived stress, and well-being in the beginning of the competitive season 2012 (T1). On two more occasions, six and 12 months later, the players completed the stress and well-being questionnaires.Results: A latent class analysis, based on the TDEQ sub-scale scores at T1, revealed three classes of players with different perceptions of their TDE (one high quality, one moderate quality, and one poor qualityclass). A second-order multivariate latent growth curve model (factor-of-curves model) showed that the class of players perceiving the lowest TDE quality, experienced higher initial level of stress and lower initial level of well-being at T1 compared to the other two classes. Moreover, there were no significant differences in slopes for neither stress nor well-being between classes (the initial difference between the three groups, in well-being, remained stable over time).Conclusion: The results indicate that players perceiving their TDE as supporting and focusing on long term development seem to be less stressed and experience higher well-being than other players. Hence, in addition to facilitate sport-specific development and performance among youth athletes, high quality TDEs may be important for youth elite athletes' general well-being.

    • Background: Regular sport participation is essential for youths physical, mental, and social health. Research shows, however, that sports participation peaks at around 10-14 years of age before declining through adolescence. Soccer, which is the most popular youth sport in Sweden, is no exception to dropout problems during adolescence. Purpose of the study: The purpose was to examine longitudinal changes in youth soccer players motivational regulations during the first year of the Covid-19 pandemic in Sweden, and how longitudinal changes in motivational regulations predicts dropout from youth soccer.Methods: Self-reported data was collected from 325 youth soccer players between 11 and 17 years of age (M = 13.08) at the beginning of the season in 2019 (TI) and 2020 (T2) and dropout data was reported by the coaches at the end of the season in 2021 (T3). Latent change score analyses, using Bayesian estimator, was used to examine change in the players motivational regulations.  Findings: There was a credible increase in amotivation (β = 0.14) and a credible decrease in identified regulation (β = -0.41) between T1 and T2. Changes in amotivation (β = 0.16), external regulation (β = 0.14), and intrinsic regulation (β = -0.15) between T1 and T2 were credible predictors of dropout from soccer at T3. Conclusion: To reduce the risk of dropout from youth soccer, during an ongoing pandemic, it is important to mitigate increases in amotivation and external regulation and to facilitate intrinsic motivation.

  • Effects of Mindfulness-Acceptance-Commitment (MAC) on Sport-Specific Dispositional Mindfulness, Emotion Regulation, and Self-Rated Athletic Performance in a Multiple-Sport Population : an RCT Study
  • 2019
  • Ingår i: Mindfulness. - New York, NY : Springer. - 1868-8527 .- 1868-8535. ; 10:8, s. 1518-1529

    • ObjectivesThe aim of the study was to examine mediating effects of emotion regulation and sport-specific dispositional mindfulness on self-rated athletic training performance, following the Mindfulness-Acceptance-Commitment (MAC) intervention, compared to a Psychological Skills Training (PST) control group.MethodsSixty-nine competitive elite athletes who did not have any prior experience with mindfulness- and acceptance-based exercises, were recruited and randomly assigned into either a MAC group or a traditional PST group. Latent growth curve analyses were performed to examine longitudinal relationships among the study variables. Mediation analyses were conducted to test if the growth trajectory of each of the proposed mediators mediated the relationship between the intervention and perceived performance (measured at T3).ResultsFindings showed that the MAC intervention had an indirect effect on self-rated athletic training performance through changes in dispositional mindfulness and emotion regulation respectively. Further, the MAC- group obtained greater post-test improvements in athletic mindfulness, emotion regulation abilities, and perceived performance compared to the PST group.ConclusionsOverall, findings suggest that dispositional athletic mindfulness and emotion regulation may function as important mechanisms in MAC, and that the MAC approach is a more effective intervention compared to the PST condition in reducing emotion regulation difficulties, as well as enhancing sport-relevant mindfulness skills and perceived athletic training performance in elite sport.

  • Mindfulness Mechanisms in Sports: Mediating Effects of Rumination and Emotion Regulation on Sport-Specific Coping
  • 2017
  • Ingår i: Mindfulness. - New York, NY : Springer Science and Business Media LLC. - 1868-8527 .- 1868-8535. ; 8:5, s. 1354-1363

    • The main objective of the project was to examine a proposed theoretical model of mindfulness mechanisms in sports. We conducted two studies (the first study using a cross-sectional design and the second a longitudinal design) to investigate if rumination and emotion regulation mediate the relation between dispositional mindfulness and sport-specific coping. Two hundred and forty-two young elite athletes, drawn from various sports, were recruited for the cross-sectional study. For the longitudinal study, 65 elite athletes were recruited. All analyses were performed using Bayesian statistics. The path analyses showed credible indirect effects of dispositional mindfulness on coping via rumination and emotion regulation in both the cross-sectional study and the longitudinal study. Additionally, the results in both studies showed credible direct effects of dispositional mindfulness on rumination and emotion regulation. Further, credible direct effects of emotion regulation as well as rumination on coping were also found in both studies. Our findings support the theoretical model, indicating that rumination and emotion regulation function as essential mechanisms in the relation between dispositional mindfulness and sport-specific coping skills. Increased dispositional mindfulness in competitive athletes (i.e. by practicing mindfulness) may lead to reductions in rumination, as well as an improved capacity to regulate negative emotions. By doing so, athletes may improve their sport-related coping skills, and thereby enhance athletic performance.

    • The dynamic pattern between burnout and sleep among athletes is unknown. This longitudinal survey examined the interplay between burnout and sleep among blind elite soccer players. China national blind soccer team players (n = 10) completed measures on burnout and sleep quality through interview at baseline (month 1), and followed at months 2, 3, 4, and 5. The results of dynamic p-technique analysis, using Bayesian estimation, showed a credible relationship between burnout and sleep quality. Also, burnout had a credible lagged effect on subsequent sleep quality whereas sleep quality did not have a credible lagged effect on burnout. The results suggest that burnout and sleep are not reciprocally related and burnout may be a risk factor of sleep problems among athletes. © 2017 Elsevier Ltd.

  • Athlete availability and incidence of overuse injuries over an athletics season in a cohort of elite Swedish athletics athletes - A prospective study
  • 2020
  • Ingår i: Injury Epidemiology. - London : Springer Science and Business Media LLC. - 2197-1714. ; 7:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Athletics is a sport with a high incidence of injury, where most injuries are caused by overuse. Research on injury incidence and the occurrence of overuse injuries during a season in athletics is scarce. An athlete availability (unrestricted ability to participate in training or competition) of less than 80% has been linked with athletes being less likely to reach their performance goals. The purpose of this study was to estimate the monthly injury incidence rates, athlete availability, and the overuse injury incidence rate per 1000 athletics-hours of training in a cohort of Swedish elite athletics athletes. Methods: The cohort consisted of 59 male and female elite athletes competing in either middle or long-distance running, sprint, or jumping events. Injury and training data were collected during one athletics season, from October to the end of August. All injury data were collected by medical professionals. Training data were collected monthly, and consisted of event-specific training diaries covering training sessions, training days, and non-training or non-competition days. Monthly injury incidence rates were based on the number of new injuries per month in relation to the number of exposed (injury-free) athletes. Results: The overall injury incidence rate for all athletes was highest in October (22.0%). Monthly injury incidence rate for middle and long-distance runners was highest in October (26.1%), for sprinters in April (19.0%), and for jumpers in October (21.4%). The overall athlete availability was 78.0% for the cohort. Sprinters had the lowest athlete availability (71.4%), followed by jumpers (77.3%), and middle-distance and long-distance runners (82.7%). Female athletes (76.5%) had a lower athlete availability than male athletes (79.7%). The injury incidence rate was 1.81 injuries per 1000 athletics hours of training. Middle and long-distance runners had the highest injury incidence rate (2.38), followed by jumpers (1.62), and sprinters (1.34). Conclusion: Monthly injury incidence rates during a season appears to correspond to periods of high training volume (conditioning phases and training camps). The low overall athlete availability (> 80%) indicates that many Swedish elite athletes are less likely to reach their full potential. © 2020 The Author(s).

  • Tidskriftsartikel (refereegranskat)abstract
    • Background Most injuries in track and field are caused by overuse with conflicting reports concerning the underlying mechanisms. The purpose of this study was to evaluate how biomechanical and clinical factors relate to the risk of overuse injuries, and to investigate whether the relationships between potential risk factors and injury become stronger if injuries are grouped by location. Methods The study is a prospective cohort study conducted during a Swedish track and field season over eleven months, from October to August. The cohort consisted of elite male and female track and field athletes competing in either middle- and long-distance running, sprinting, jumping, or throwing events (n = 96). Athletes performed a baseline screening at enrollment consisting of a clinical examination, running, and strength tests. Injury data was collected during the season by medical professionals and divided according to their anatomical location into upper-body, thigh/hip, knee, or foot/shank injuries. Results Thirty-four (54.8%) injuries where located at the foot/shank, followed by sixteen injuries at the thigh/hip (25.8%). Only eight knee (12.9%) and four upper-body (6.5%) injuries were registered during the season and therefore not analysed. Effect sizes were calculated for all test variables. Small effect sizes (r(pb) = .10-.23) were found for eleven risk factors between the overall injured (all injuries combined) and non-injured athletes. By further sub-grouping the injured group into thigh/hip injuries, effect size increased in hip adduction range of motion knee flexion velocity and the muscle flexibility of the iliopsoas. For foot/shank injuries, only the hamstring:quadriceps strength ratios increased for the right side to a small effect size. Conclusions Injury grouping appears to increase effect size for certain risk factors. Athletes with a slower knee flexion velocity during stance phase were more likely to become injured (p-value <.03, r(pb) = .37). An increased cohort size to further sub-divide injuries into specific diagnoses is needed.

  • Put Some Music on : The Effects of pre-Task Music Tempo on Arousal, Affective State, Perceived Exertion, and Anaerobic Performance
  • 2023
  • Ingår i: Music & Science. - London : Sage Publications. - 2059-2043. ; 6
  • Tidskriftsartikel (refereegranskat)abstract
    • Research on the ergogenic effects of music on athletic performance usually includes multiple antecedents simultaneously. Consequently, this study set out to isolate a single antecedent using a highly controlled experiment. More specifically, the aim of the study was to investigate the effect of pre-task, slow- and fast-tempo music on arousal, affective state, perceived exertion, and anaerobic rowing performance by isolating music tempo as the sole intrinsic musical factor. Forty young adults (male = 23, female = 17) participated in three trials where they all were exposed to no-music, slow-tempo, and fast-tempo music conditions in a randomized order. The music was exclusively composed for this study and equally novel for all participants. It was based on the same electronic track with a techno-orientation rendered to both 110 (slow-tempo) and 140 (fast-tempo) BPM. Following music exposure, the participants were momentarily asked to report levels of felt arousal and affective state before being instructed to perform a 30-s maximal rowing test on an ergometer. Upon completion of each rowing test, subjects were then asked to report their perceived exertion. Both fast- and slow-tempo pre-task music exposure led to increased arousal and positive affective state when compared to no music. Fast-tempo music led to a significantly higher mean power output than slow-tempo music. No significant differences were found for peak watt output or rating of perceived exertion when comparing all conditions. These findings suggest that exposure to pre-task music may offer positive psychological benefits prior to commencing anaerobic sporting tasks. Results also suggest that fast-tempo music may have an ergogenic effect on anaerobic performance. © The Author(s) 2023.

    • Objectives: The aims of the present study were to: (a) examine longitudinal measurement invariance in the Swedish version of the Behavioral Regulations in Sport Questionnaire (BRSQ) and (b) examine the continuum hypothesis of motivation as postulated within self-determination theory. Design: Two-wave survey. Method: Young competitive athletes (N = 354) responded to the BRSQ early in the season (November) and at the end of the athletic season (April). Data were analyzed using exploratory structural equation modeling (ESEM) and bifactor ESEM. Results: We found support for strict longitudinal measurement invariance in the BRSQ. Latent mean comparisons showed an increase in external regulation and amotivation across the season. The latent factor correlations indicated some deviations from a simplex pattern related to amotivation, external regulation, and introjected regulation. In the bifactor model, intrinsic motivation items had negative factor loadings on the global factor, identified regulation items had factor loadings approaching zero, and introjected and external regulation and amotivation items all had moderate to strong positive factor loadings. Conclusion: The present study adds longitudinal measurement invariance to the psychometric evidence of the BRSQ. Research on why the latent means of the behavioral regulations changed over the athletic season is warranted. The continuum hypothesis was partially supported. Latent factor correlations and factor loadings on the global factor in the bifactor ESEM highlighted that the discriminant validity of the controlled regulations and amotivation needs further investigation. © 2018 Elsevier Ltd

  • Longitudinal associations between athletes' controlled motivation, ill being, and perceptions of controlling coach behaviors: A Bayesian latent growth curve approach

    • Although many scholars have argued that leadership is a dynamic process jointly produced by leaders and followers, leadership in sports is most often researched as a unidirectional process from coaches to athletes. Within self-determination theory (SDT), individual characteristics are suggested to influence how people perceive external events such as coaches' behaviors. In the present study, we examined this jointly produced leadership process by investigating longitudinal associations between athletes' controlled motivation, ill-being, and perceptions of coaches' controlling behaviors at the between- and within-person levels. The participants were 247 young elite skiers enrolled at Swedish sport high schools who responded to self-report questionnaires at three time points over the course of an athletic season. At the between-person level, increases in perceptions of coaches' controlling behaviors over the season positively predicted controlled motivation at the end of the season, and controlled motivation at the beginning of the season positively predicted ill-being at the end of the season. At the within-person level, athletes' controlled motivation positively predicted perceptions of coaches' controlling behaviors. The results at the between-person level support the unidirectional perspective and the tenets of SDT. The results at the within-person level suggest that individual characteristics such as motivation can influence how athletes perceive external events, which has been proposed theoretically but seldom examined empirically. Three plausible explanations for this reversed association are presented in the discussion. (C) 2017 Elsevier Ltd. All rights reserved.

    • The ability to examine within-person change is essential to test process-based theories in sport and exercise psychology. Longitudinal data, whether experimental or observational, are prerequisites to be able to examine change processes, but most longitudinal studies in sport and exercise psychology focus solely on between-person/group differences, not on within-person change. In this review, we (1) provide researchers in the sport and exercise psychology field with a framework for longitudinal research that focuses on within-person change; (2) provide an overview of how researchers in sport and exercise psychology currently analyse longitudinal data, which showed that most longitudinal studies focus on between-person/group differences; and (3) provide examples of statistical models for analysing longitudinal data that correspond to the framework for longitudinal research. In the examples, we focus on latent variable modelling, such as latent growth-curve modelling and latent change-score modelling, which capture within-person change. We argue that there is a need for stronger emphasis on the match among theory of change, temporal design, and statistical models when designing longitudinal studies in sport and exercise psychology.

  • Using bifactor exploratory structural equation modeling to examine global and specific factors in measures of sport coaches’ interpersonal styles
  • 2015
  • Ingår i: Frontiers in Psychology. - Lausanne : Frontiers Media SA. - 1664-1078. ; 6
  • Tidskriftsartikel (refereegranskat)abstract
    • In the present work we investigated distinct sources of construct-relevant psychometric multidimensionality in two sport-specific measures of coaches’ need-supportive (ISS-C) and controlling interpersonal (CCBS) styles. A recently proposed bifactor exploratory structural equation modeling (ESEM) framework was employed to achieve this aim. In Study 1, using a sample of floorball players, the results indicated that the ISS-C can be considered as a unidimensional measure, with one global factor explaining most of the variance in the items. In Study 2, using a sample of male ice hockey players, the results indicated that the items in the CCBS are represented by both a general factor and specific factors, but the subscales differ with regard to the amount of variance in the items accounted for by the general and specific factors. These results add further insight into the psychometric properties of these two measures and the dimensionality of these two constructs.

  • Ingår i: Qualitative Research in Sport, Exercise and Health. - Abingdon, Oxon : Routledge. - 2159-676X .- 2159-6778. ; 8:1, s. 1-20
  • Tidskriftsartikel (refereegranskat)abstract
    • This article concerns some central aspects of methodology in qualitative research: the participants’ and investigators’ storytelling, and the main instruments in many interview-based qualitative studies, the researchers themselves. We discuss several ethical and interpersonal aspects of qualitative research encounters between investigators and their interviewee participants. Interviewing research participants is a fundamentally exploitative process, and we make suggestions for how we can temper that exploitation by giving something of value back to our participants and to make sure the well-being of the participant is not compromised by our actions. Many research topics in qualitative studies concern experiences of stress, distress and trauma, and interviewees re-telling their stories may become retraumatised. Such retraumatisation constitutes abuse on the part of the researcher. To counter potential abuse and exploitation, we discuss how researchers, as the central instruments in interview-based investigations, can use knowledge of interpersonal neurobiology, psychodynamic theory and mindful practice to enable them to hold their participants (and their participants’ stories) in loving care and maybe even help in healing processes. © 2015 Taylor & Francis

  • Longitudinal associations between perceived programme quality, basic needs support and basic needs satisfaction within youth sport : A person-centred approach
  • 2020

    • Acknowledging the importance of longitudinal data to test process-based psychological theories of motivation is critical. The purpose of this study was to use a person-centred approach to identify unique subgroups (i.e. profiles) of youth athletes based on their level of self-reported programme quality (PQ) and basic needs support mid-way through their sport season and investigate potential differences between the subgroups on their self-reported basic needs satisfaction at the end of the sport season. The current study involved 541 Canadian youth athletes (males n = 289; females n = 250; gender-fluid n = 2) within 52 sport programmes over the course of 18 months. Youthathletes ranged in age from 8 through 19 (M = 13.76, SD = 2.61). A latent profile analysis (LPA) in Mplus 8.0 was used to carry out the analyses. The LPA revealed three distinct profiles based on youth athletes’ levels of self-reported PQ and basic needs support. Specifically, athletes who perceived their sport experience to be of higher quality and supported their basic psychological needs midway through the sport season also reported higher levels of basic needs satisfaction at season end. Results from this study contribute to the field of sport psychology through understanding how basic needs theory contributes to the dimensions of programme quality and by informing recommendations for future coach education on how to satisfy youth athletes’ basic psychological needs for autonomy, competence, and relatedness through programmedelivery. © 2018 International Society of Sport Psychology

    • Objectives: Studies including people with severe mental illness (SMI) have reported beneficial effects from physical activity (PA) on psychiatric symptoms, quality of life, and global functioning. However, it is important to be regularly physically active to obtain these effects. Using the motivational lens of self-determination theory, the aim of the current study was to explore the dynamic interplay between satisfaction of psychological needs (autonomy, competence, relatedness) in PA and the patients' weekly PA level.Methods: The study had a longitudinal design, following 10 inpatients with du& diagnoses (SMI and addiction) over 12 weeks at a psychiatric ward offering physical activity as part of treatment Data were collected 14 times with a questionnaire measuring psychological need satisfaction, while an accelerometer was used to objectively count steps to reflect participants average PA-level each week. To analyse the week-to-week relationships between the basic psychological needs and PA-level, the Bayesian dynamic p-technique analysis was used to explore both cross-sectional-, autoregressive- as well as cross-lagged effects between the constructs.Results: The results indicated credible and strong positive autoregressive effects for all three psychological needs as well as for PA-level, and positive credible cross-sectional associations between all three psychological needs and PA-level. However, the cross-lagged effects were small and not credible for all three psychological needs in relation to PA-level.Conclusions: In total, these results support the established positive relation between basic psychological need satisfaction and PA-level yet failed in finding any predictive effects between need satisfaction and PA-level. © 2021 The Author(s).

  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study was to explore how perceptions of coaches’ behaviour affected athletes’ wellbeing, by examining: (a) the potential change in perceptions of need-support from the coach (over an academic year), and (b) the within-person relationship between the three aspects of need-supportiveness and subjective vitality at the end of the winter sport season. Elite student athletes (N = 102, M age = 17.04) completed a questionnaire three times. Bayesian growth curve analyses showed that perceptions of relatedness and autonomy support were stable and high throughout the year. In contrast, perceptions of competence support decreased during the season. In addition, the results showed a credible positive within-person relationship between changes in all three facets of needsupportiveness from the coach and vitality measured at the end of the season, which supports SDT tenets. These findings reveal the importance of need-support for athletes’ well-being, and show that competence support needs extra attention in the elite sport context where competence satisfaction is constantly challenged.

  • Organizational Readiness for Change (ORC) test used in the implementation of assessment instruments and treatment methods in a Swedish National study
  • 2018
  • Ingår i: Journal of Substance Abuse Treatment. - Amsterdam : Elsevier. - 0740-5472 .- 1873-6483. ; 84, s. 9-16
  • Tidskriftsartikel (refereegranskat)abstract
    • Organizational climate and related factors are associated with outcome and are as such of vital interest for healthcare organizations. Organizational Readiness for Change (ORC) is the questionnaire used in the present study to assess the influence of organizational factors on implementation success. The respondents were employed in one of 203 Swedish municipalities within social work and psychiatric substance/abuse treatment services. They took part in a nationwide implementation project organized by the Swedish Association of Local Authorities and Regions (SALAR), commissioned by the Swedish National Board of Health and Welfare. Aim The aims were: (a) to identify classes (clusters) of employees with different ORC profiles on the basis of data collected in 2011 and (b) to investigate ORC profiles which predicted the use of assessment instruments, therapy methods and collaborative activities in 2011 and 2013. Design and recruitment The evaluation study applied a naturalistic design with registration of outcome at consecutive assessments. The participants were contacted via official e-mail addresses in their respective healthcare units and were encouraged by their officials to participate on a voluntary basis. Statistics Descriptive statistics were obtained using SPSS version 23. A latent profile analysis (LPA) using Mplus 7.3 was performed with a robust maximum likelihood estimator (MLR) to identify subgroups (clusters) based on the 18 ORC indexes. Results A total of 2402 employees responded to the survey, of whom 1794 (74.7%) completed the ORC scores. Descriptive analysis indicated that the respondents were a homogenous group of employees, where women (72.0%) formed the majority. Cronbach's alpha for the 18 ORC indexes ranged from α = 0.67 to α = 0.78. A principal component analysis yielded a four-factor solution explaining 62% of the variance in total ORC scores. The factors were: motivational readiness (α = 0.64), institutional resources (α = 0.52), staff attributes (α = 0.76), and organizational climate (α = 0.74). An LPA analysis of the four factors with their three distinct profiles provided the best data fit: Profile 3 (n = 614), Profile 2 (n = 934), and Profile 1 (n = 246). Respondents with the most favorable ORC scores (Profile 3) used significantly more instruments and more treatment methods and had a better collaborating network in 2011 as well as in 2013 compared to members in Profile 1, the least successful profile. Conclusion In a large sample of social work and healthcare professionals, ORC scores reflecting higher institutional resources, staff attributes and organizational climate and lower motivational readiness for change were associated with a successful implementation of good practice guidelines for the care and treatment of substance users in Sweden. Low motivational readiness as a construct may indicate satisfaction with the present situation. As ORC proved to be an indicator of successful dissemination of evidence-based guidelines into routine and specialist healthcare, it can be used to tailor interventions to individual employees or services and to improve the dissemination of and compliance with guidelines for the treatment of substance users. © 2017

  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • The overall aim of the thesis was to increase knowledge of health among people with psychotic disorders such as schizophrenia and other long-term psychotic conditions. The aim was also to investigate health effects, in terms of clinical health outcomes and self-reported questionnaires, of atwo-year individualized lifestyle intervention implemented in psychiatric outpatient services involving cooperation with the municipal social psychiatry services. The motivation for the study was to generate new knowledge in order to be able to promote health in people with psychotic disorders and to improve the care and support provided for this target group. The thesis consists of four studies. A quantitative study (Study I), was conducted using a cross-sectional design to investigate the prevalence of overweight, obesity, risk of cardiovascular disease (CVD) and the relationships between self-rated salutogenic health, sense of coherence, CVD risk, and body mass index among people with psychoticdisorders (n=57). The study was conducted in four psychiatric outpatient services; questionnaires were completed by the participants and clinical health measurements were collected by the participant’s contact nurse at the psychiatric outpatient services. The participants showed a moderate/high risk of CVD, the mean for BMI was 31.9 (59.6% were obese) and 31.6% were overweight. The results did not reveal any relationships between the subjective and objective measuresof health indicating the need for both subjective and objective assessments of health in psychiatric care. In a qualitative study (Study II), data were collected with semi-structured interviews (n=16) andanalyzed with qualitative content analysis. The interviews resulted in an overall theme “Being regarded as a whole human being by self and others”, which showed the multidimensional nature of health and the issues that enable healthy living among people with severe mental illness. Three categories emerged: (i) everyday structure (ii), motivating life events and (iii) support from significant others. The results indicate that a person with severe mental illness needs to be encountered as a wholeperson if healthy living is to be enabled. In a quasi-experimental study (Study III), the potential effects of participation in the two-year lifestyle intervention (intervention group n=54 and control group (n=13) were investigated. The data were collected at baseline, after 12 months and after 24 months using the self-reported questionnaire the Salutogenic Health Indicator Scale (SHIS), the Hopkins Symptom Checklist (HSCL-25) and the National Public Health Survey. Measures of clinical healthoutcomes were conducted by the participant’s contact nurse at the psychiatric outpatient services. Multilevel modeling was used to test differences in changes over time. Significant changes were foundin physical activity, HbA1c and waist circumference after participation in individualized lifestyle intervention. The relationship between changes in physical activity, levels of salutogenic health and glycated hemoglobin (Hb1Ac) were investigated (n=54) in Study IV. The data were collected atbaseline, after 12 months and after 24 months using the self-reported questionnaires Salutogenic Health Indicator Scale (SHIS) and National Public Health Survey. Within-person changes in physical activity between baseline and at the end of the twenty-four-month intervention were calculated. Selfreported increased physical activity was positively associated with self-rated salutogenic health and negatively associated with level of HbA1c after participation in the intervention. The thesis shows that a well-founded assessment of general health needs must consider both the individual's subjective experiences and objective measurements in order to form a solid foundation for dialogue and shareddecision-making about essential care services. The results also show that it is possible to stimulate healthy behavioral changes with a two-year individualized lifestyle intervention and bring both subjectively and objectively measured health benefits for people with psychotic disorders. The importance of nurses in psychiatric care applying a holistic approach and integrating lifestyle interventions into daily person-centered psychiatric care in collaboration with other healthcare providers to facilitate changes towards a healthy lifestyle in persons with psychotic illness is emphasized in the thesis.

    • People with psychotic disorders experience to a great extent avoidable physical illnesses and early mortality. The aim of the study was to investigate the potential effects for this group of participating in a lifestyle intervention. A multi-component nurse-led lifestyle intervention using quasi-experimental design was performed. Changes in biomedical and clinical measurements, self-reported health, symptoms of illness and health behavior were investigated. Multilevel modeling was used to statistically test differences in changes over time. Statistically significant changes were found in physical activity, HbA1c and waist circumference. A lifestyle intervention for people with severe mental illness can be beneficial for increasing physical activity.

    • Life expectancy is greatly reduced in patients with schizophrenia, and cardiovascular diseases are a leading cause of mortality. The aim of this cross-sectional study was to investigate the prevalence of overweight, obesity, and cardiovascular disease (CVD) risk and to investigate the relationships between self-rated health, sense of coherence, CVD risk, and body mass index (BMI) among people with severe mental illness (SMI) in psychiatric outpatient settings. Nearly 50% of the participants were exposed to moderate/high risk of CVD and over 50% were obese. The results showed no statistically relationships between the subjective and objective measures (Bayes factor <1) of health. The integration of physical health into clinical psychiatric nursing practice is vital.

    • People with psychotic disorders have a significantly increased risk of physical diseases and excessive mortality rates. The aim of the study was to investigate relationships between changes in physical activity, levels of salutogenic health, and glycated hemoglobin among people with psychotic disorders after participation in an individualized lifestyle intervention. The results from analyses showed that self-reported increased physical activity was positively associated with the level of salutogenic health and negatively associated with the level of HbA1c on an individual level. The results indicate that coordinated, individualized, holistic and health-promoting nursing care is crucial to enabling enhanced lifestyle within this vulnerable target group. © 2023 The Author(s).

  • Development of basic psychological need satisfaction in physical education : Effects of a two-year PE programme
  • 2019
  • Ingår i: Journal for Research in Arts and Sports Education. - Oslo : Cappelen Damm Akademisk. - 2535-2857. ; 3:2, s. 4-21
  • Tidskriftsartikel (refereegranskat)abstract
    • Research shows that sports-active students experience more basic need satisfaction (autonomy, competence, relatedness) in physical education (PE) than their non-sports-active peers, and thus, reap most of the benefits of PE. This study aimed to investigate the role of a two-year PE programme, referred to as Interest-based PE, in contributing to students’ basic need satisfaction in PE, and in particular, to assess potential basic needs-benefits among students who were not involved in leisure-time sport. Among 693 students, 348 were offered a choice of two different PE approaches (“explorative” vs. “sports” approach) for the next two years, while the remaining students continued to receive traditional PE. Girls, non-sports-active students, and students who experienced less need satisfaction in PE at baseline were more likely to choose the explorative approach, thereby signifying a wish for a less sports-centred PE. However, no significant differences in autonomy, competence, and relatedness need satisfaction were identified between Interest-based PE groups and their respective control groups over the course of the programme. Sports active students experienced more gains in relatedness need satisfaction than non-sports active students over the course of the programme, suggesting that challenges in promoting equal opportunities for learning in PE may require more than “Interest-based PE”.

  • Global Self-Worth among Adolescents : The Role of Basic Psychological Need Satisfaction in Physical Education
  • 2020
  • Ingår i: Scandinavian Journal of Educational Research. - Abingdon : Routledge. - 0031-3831 .- 1470-1170. ; 64:5, s. 768-781
  • Tidskriftsartikel (refereegranskat)abstract
    • Global self-worth is important for healthy development and learning, and is therefore highlighted as a major aim in the Norwegian physical education (PE) curriculum. Based on prior research this study aimed to assess potential differences in global self-worth and contextual basic need satisfaction among 2854 adolescents (47.5% boys, 52.5% girls, ages 13 and 16) participating in different movement contexts, and to determine whether basic need satisfaction in PE relates to global self-worth. Structural equation modeling analyses indicate that basic need satisfaction in PE relates significantly to global self-worth. However, adolescents who do not participate in movement contexts outside school report significantly lower basic need satisfaction in PE compared to their sports-active peers, and could possibly therefore experience reduced global self-worth development through PE. Findings support research showing that sports active youth reap most of the benefits of PE, and thus, that PE violates the principles of equal education. © 2019 The Author(s).

  • Assessing the individual relationships between physical test improvements and external load match parameters in male professional football players-a brief report
  • 2024
  • Ingår i: Frontiers in Sports and Active Living. - Lausanne : Frontiers Media S.A.. - 2624-9367. ; 6
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: This study aimed to explore whether a meaningful improvement in physical performance following an in-season strength training intervention can be related to external load match parameters at an individual level in professional male football players.Methods: Eight male professional football players (25.4 ± 3.1 years, 184.1 ± 3.4 cm, 79.3 ± 2.2 kg) completed a 10-week strength intervention period in addition to football-specific training and matches. Commonly used physical and external load measures were assessed before and after intervention. Physical performance improvements had to exceed the measurement’s typical error and the smallest worthwhile difference (SWD) to be considered meaningful. External load match parameters were assessed before and after the intervention period using SWD and non-overlap of all pairs (NAP) analysis. A Bayesian pairwise correlation analysis was performed to evaluate relationships between changes in physical performance and external load match parameters.Results: Three players displayed meaningful improvements in two to five physical performance measures. However, positive changes exceeding the SWD and positive effects in NAP results were observed for all players in external load match parameters. Kendall's tau correlation analysis showed evidence (base factor >3) for only one correlation (maximum speed − decelerations, τ = −0.62) between the changes in physical performance and external load measures, while the remaining comparisons exhibited no relation.Conclusions: The findings suggest that improvements in physical performance may not necessarily translate to improvements in external load match parameters. Further research, with larger sample sizes, is needed to understand potential mechanisms between acute and chronic physical performance changes and football external load parameters during training and matches.© Copyright 2024 Byrkjedal, Bjørnsen, Luteberget, Ivarsson and Spencer

  • Association Between Physical Performance Tests and External Load During Scrimmages in Highly Trained Youth Ice Hockey Players
  • 2023
  • Ingår i: International Journal of Sports Physiology and Performance. - Champaign, IL : Human Kinetics. - 1555-0265 .- 1555-0273. ; 18:1, s. 47-54
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: To investigate the relationship between physical performance tests and on-ice external load from simulated games (scrimmages) in ice hockey. METHODS: A total of 14 players completed a physical performance test battery consisting of 30-m sprint test-run and 30-m sprint test-skate (including 10-m split times and maximum speed), countermovement jump, standing long jump, bench press, pull-ups, and trap bar deadlift and participated in 4 scrimmages. External load variables from scrimmages included total distance; peak speed; slow (< 11.0 km/h), moderate (11.0-16.9 km/h), high (17.0-23.9 km/h), and sprint (> 24.0 km/h) speed skating distance; number of sprints; PlayerLoad™; number of high-intensity events (> 2.5 m/s); accelerations; decelerations; and changes of direction. Bayesian pairwise correlation analyses were performed to assess the relationship between physical performance tests and external load performance variables. RESULTS: The results showed strong evidence (Bayes factor > 10) for associations between pull-ups and high-intensity events (τ = .61) and between maximum speed skate and peak speed (τ = .55). There was moderate evidence (Bayes factor >3 to <10) for 6 associations: both maximum speed skate (τ = .44) and countermovement jump (τ = .44) with sprint speed skating distance, countermovement jump with number of sprints (τ = .46), pull-ups with changes of direction (τ = .50), trap bar with peak speed (τ = .45), and body mass with total distance (τ = .49). CONCLUSION: This study found physical performance tests to be associated with some of the external load variables from scrimmages. Nevertheless, the majority of correlations did not display meaningful associations, possibly being influenced by the selection of physical performance tests.

  • In-season autoregulation of one weekly strength training session maintains physical and external load match performance in professional male football players
  • 2023
  • Ingår i: Journal of Sports Sciences. - : Routledge. - 0264-0414 .- 1466-447X. ; 41:6, s. 536-546
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study was to compare the effects of autoregulating strength training volume based on an objective (external load match performance) versus a subjective (self-selected) method in professional male football players. Sixteen players completed a 10-week strength training programme where the number of sets was regulated based on football match high-intensity running distance (HIR >19.8 km/h, AUTO, n = 7), or self-selected (SELF, n = 9). In addition to traditional physical performance assessments (30-m sprint, countermovement jump, leg-strength, and body composition), external load match performance was assessed with five matches in the beginning and in the end of the study period. Both groups performed ~ 1 weekly bout of ~ 6 sets in leg extensor exercises during the 10-week period, and maintained physical performance during the competitive season, with no group differences detected after the training period. Non-overlap of all pairs (NAP) analysis showed weak-to-moderate effects in external load match performance from before to after the study period, suggesting that players maintained or improved their performance. In conclusion, no group differences were observed, suggesting that both external load autoregulated and self-selected, low-volume in-season strength training maintained physical, and external load match performance in professional male football players. © 2023 The Author(s).

  • Simulated Game-Based Ice Hockey Match Design (Scrimmage) Elicits Greater Intensity in External Load Parameters Compared With Official Matches
  • 2022
  • Ingår i: Frontiers in Sports and Active Living. - Lausanne : Frontiers Media S.A.. - 2624-9367. ; 4
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: A limited number of studies have explored the external load experienced in indoor sports such as ice hockey, and few the link between training and match performance. As a paucity exists within this topic, this study explored whether a simulated match design (i.e., scrimmage) could be representative of official match demands and elicit similar external loads as in official matches in a group of elite youth male ice hockey players.Methods: A total of 26 players were monitored during eight official and four simulation matches using a Local Positioning System. Total distance, max velocity, slow (0–10.9 km/h), moderate (11–16.9 km/h), high (17.0–23.9 km/h), and sprint (>24 km/h) speed skating distance, distance per min, PlayerLoadTM, PlayerLoadTM per min, high-intensity events (HIEs) (>2.5 m/s−2), acceleration (ACCs), decelerations (DECs), and change of directions (CODs) were extracted from the tracking devices. A two-level regression analysis was conducted to compare the difference between match types when controlling for time on ice, match day, and position.Results: Between match-type results showed a credible difference in all variables except max velocity and ACCs. Distance per min was 27.3% higher during simulation matches and was explained by a 21.3, 24.1, and 14.8% higher distance in sprint-, high-, and moderate speed skating distance, while slow speed-skating distance was 49.2% lower and total distance only trivially different from official to simulation matches. Total PlayerLoadTM was 11.2% lower, while PlayerLoadTM per min was 8.5% higher during simulation matches. HIEs, CODs, and DECs were 10.0, 11.9, and 22.3% higher during simulation matches.Conclusion: The simulated match design is related to official match demands with comparable match-time, playing time, number of shifts, and shift duration. However, simulation matches provoked a higher external load output compared with official matches, possibly explained by a more continuous movement design. A game-based simulation match design can therefore be utilized when match-related actions at high intensity are warranted. © 2022 Byrkjedal, Luteberge, Bjørnsen, Ivarsson and Spencer.
