- 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.

- The aim of the current study was to examine actor and partner effects of (a) athletes’ and coaches’ attachment styles (avoidant and anxious) on the quality of the coach-athlete relationship, and (b) athletes’ and coaches’ quality of the coach-athlete relationship on relationship satisfaction employing the actor-partner interdependence model (Kenny, Kashy, & Cook, 2006). Coaches (N = 107) and athletes (N = 107) completed a questionnaire related to attachment styles, relationship quality, and relationship satisfaction. Structural equation model analyses revealed (a) actor effects for coaches’ and athletes’ avoidant attachment styles on their own perception of relationship quality and coaches’ and athletes’ perception of relationship quality on their own perception of relationship satisfaction, and (b) partner effects for athletes’ avoidant attachment style on coaches’ perceptions of relationship quality and for coaches’ perceptions of relationship quality on athletes’ perceptions of relationship satisfaction. The findings highlight that attachments styles can help us understand the processes involved in the formation and maintenance of quality relational bonds between coaches and athletes.

Tidskriftsartikel (refereegranskat)abstract
- The aim of the study was to examine the influence of smartphone use on time perception during exercise. Twenty-four physically active participants (16 females, MVO2max = 43.0 ml/kg/min; 8 males, MVO2max = 56.9 ml/kg/min; Mage = 24.40, SD = 4.35) completed an experimental study comprised of randomized conditions alternating between cycling at a hard intensity and seated rest, whilst their smartphone was: a) used to view ‘Tik Tok’ videos; b) present but not viewed; or c) out of sight. In each condition participants were asked to verbally produce a target amount of time (i.e., 37s) during the trial and upon its completion estimate the duration of the trial (i.e., 330s). Repeated measures ANOVAs indicated smartphones significantly affected participants’ perception of time during and following intervals of cycling and rest. Bonferroni corrected post hoc tests showed that the time production during cycling viewing was significantly shorter when watching videos compared to when the phone was present but not viewed (Mdiff = −6.19, p = .012), 95% CI [−11.2, −1.17], as well as when the phone was out of sight (Mdiff = −4.65, p = .022), 95% CI, [−8.72, −.575]. Following each condition participants estimated the duration of the trial was less time than actual chronometric time, a significant effect of the smartphone conditions was observed F(2, 44) = 7.10, p = .002, ηp2 = .24, although not of physical activity F(1, 23) = 3.33, p = .08, ηp2 = .13. Participants were more accurate in estimating the duration of the trial when they viewed videos on their smartphone. The results of the present study suggest that viewing videos on a smartphone can induce participants to perceive time passing more quickly during exercise, and upon completion of the physical activity judge the duration of exercise to be less than reality.

The Temporal Relations of Adolescents’ Basic Need Satisfaction in Physical Education and Global Self-Worth
- 2020
-

Tidskriftsartikel (refereegranskat)abstract
- This study investigated the temporal relations of adolescents’ basic need satisfaction in physical education (PE) and global self-worth in a sample of 3,398 lower and upper secondary school students (49% boys, 51% girls, average age T1 = 15.00, SD = 1.79). Four models and competing hypotheses were tested, and the model with bidirectional paths specified showed the best fit to the data. The bidirectional effect estimates suggest not only that basic need satisfaction in PE predicts global self-worth development but also that adolescents’ perceptions of global self-worth predict the degree to which they experience basic need satisfaction in PE. Findings could suggest that students with low global self-worth are less sensitive to basic need support in PE. These students may need personally tailored need-supportive initiatives in order to develop basic need satisfaction in PE and, thus, global self-worth through PE. © 2020 Human Kinetics, Inc.

Cross-Sectional and Longitudinal Associations Between Athlete Burnout, Insomnia, and Polysomnographic Indices in Young Elite Athletes
- 2018

Ingår i: Journal of Sport & Exercise Psychology (JSEP). - CHAMPAIGN, IL, USA : Human Kinetics. - 0895-2779 .- 1543-2904. ; 40:6, s. 312-324

Tidskriftsartikel (refereegranskat)abstract
- Few studies have examined the association between sleep and burnout symptoms in elite athletes. We recruited 257 young elite athletes (M-age = 16.8 years) from Swiss Olympic partner schools. Of these, 197 were reassessed 6 months later. Based on the first assessment, 24 participants with clinically relevant burnout symptoms volunteered to participate in a polysomnographic examination and were compared with 26 (matched) healthy controls. Between 12% and 14% of young elite athletes reported burnout symptoms of potential clinical relevance, whereas 4-11% reported clinically relevant insomnia symptoms. Athletes with clinically relevant burnout symptoms reported significantly more insomnia symptoms, more dysfunctional sleep-related cognitions, and spent less time in bed during weeknights (p<.05). However, no significant differences were found for objective sleep parameters. A cross-lagged panel analysis showed that burnout positively predicted self-reported insomnia symptoms. Cognitive-behavioral interventions to treat dysfunctional sleep-related cognitions might be a promising measure to reduce subjective sleep complaints among young elite athletes.

- The aims of this study were to assess the cross-cultural invariance of athletes' self-reports of mental toughness and to introduce and illustrate the application of approximate measurement invariance using Bayesian estimation for sport and exercise psychology scholars. Athletes from Australia (n = 353, M-age = 19.13, SD = 3.27, men = 161), China (n = 254, M-age = 17.82, SD = 2.28, men = 138), and Malaysia (n = 341, M-age = 19.13, SD = 3.27, men = 200) provided a cross-sectional snapshot of their mental toughness. The cross-cultural invariance of the mental toughness inventory in terms of (a) the factor structure (configural invariance), (b) factor loadings (metric invariance), and (c) item intercepts (scalar invariance) was tested using an approximate measurement framework with Bayesian estimation. Results indicated that approximate metric and scalar invariance was established. From a methodological standpoint, this study demonstrated the usefulness and flexibility of Bayesian estimation for single-sample and multigroup analyses of measurement instruments. Substantively, the current findings suggest that the measurement of mental toughness requires cultural adjustments to better capture the contextually salient (emic) aspects of this concept.

- Null hypothesis significance testing (NHST) is like an immortal horse that some researchers have been trying to beat to death for over 50 years but without any success. In this article we discuss the flaws in NHST, the historical background in relation to both Fisher's and Neyman and Pearson's statistical ideas, the common misunderstandings of what p < .05 actually means, and the 2010 APA publication manual's clear, but most often ignored, instructions to report effect sizes and to interpret what they all mean in the real world. In addition, we discuss how Bayesian statistics can be used to overcome some of the problems with NHST. We then analyze quantitative articles published over the past three years (2012-2014) in two top-rated sport and exercise psychology journals to determine whether we have learned what we should have learned decades ago about our use and meaningful interpretations of statistics.
