- 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.

- Studies have demonstrated that being bullied in childhood may have long-term associations with lower psychological well-being in adulthood. However, although bullying incidents frequently target the victim’s body and appearance, research has overlooked studying victims’ long-term body image development and risk of engaging in disordered eating later in life. This 14-year longitudinal research project examined childhood bullying in relation to body image development and disordered eating in emerging adulthood. Growth curve analyses of participants’ body image at ages 10–21 years (N = 960) revealed that more victimized children experienced more body dissatisfaction at baseline and maintained their negative body image throughout adolescence and into adulthood. Mediation analyses showed that childhood bullying (age 10 years) predicted more negative body image in adolescence (age 18 years), which in turn predicted more disordered eating in adulthood (age 24 years). The indirect effect was stronger for girls than for boys. The findings suggest that bullied children are likely to face both more body image problems and disordered eating as they evolve through adolescence and into adulthood, indicating the need for early and effective interventions. Incorporating components known to promote a more positive body image could be a valuable feature of future interventions. Thus, as children and adolescents are taught to cope with bullying situations, they could also be helped to deal with the appearance culture that permeates many of these situations.

- Objectives To examine bidirectional within- and between-person relations between physical activity and cognitive function across 15 years. Methods Participants (N = 1,722, age range 40-85 years, 55% women) were drawn from the Betula prospective cohort study. We included 4 waves of data. Bivariate latent curve models with structured residuals were estimated to examine bidirectional within- and between-person relations between physical activity and cognitive function (episodic memory recall, verbal fluency, visuospatial ability). Results We observed no statistically significant bidirectional within-person relations over time. Higher levels of physical activity at baseline were related to less decline in episodic memory recall. Positive occasion-specific within- and between-person relations were observed, with the most consistent being between physical activity and episodic memory recall. Discussion The lack of bidirectional within-person relations indicates that shorter time lags may be needed to capture time-ordered within-person relations. The link between higher physical activity at baseline and less decline in episodic memory recall over time may indicate a protective effect of physical activity on episodic memory recall.

- In the present study, we decomposed between- and within-person effects and examined moderators of the longitudinal physical activity-cognition association. Participants (N = 1722) were drawn from the Betula study and we included four waves of data across 15 years. Bayesian multilevel modeling showed that self-reported physical activity did not predict changes in cognitive function. Physical activity positively predicted cognitive performance at baseline, and the relations were stronger for more active (compared to less active) older adults. Physical activity had a positive within-person effect on cognitive function. The within-person effect of physical activity on episodic memory recall was stronger for participants who on average engaged in less physical activity. The within-person effect on verbal fluency was stronger for participants with more education. Our results suggest that preserving cognitive functioning in old age might be more a matter of what you do in old age than reflecting what you did earlier in life.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of the study was to test longitudinal (2 years across three occasions) associations between sport participation (SP) and self-esteem (SE) across adolescence (10–18 years), addressing the mediating role of perceived sport competence (PSC) from a developmental perspective. Three waves of data were collected from three age cohorts (10–12, 13–15, and 16–18 years) of school-aged youth (N = 1358). The results demonstrate that SP and SE are related across time and that PSC has an important mediating role in this relationship, both from a skill development and a self-enhancement perspective. In the skill development model, the mediating role of PSC was significantly stronger in the youngest cohort whereas the effect of PSC on subsequent SP in the self-enhancement model was significantly stronger in the 13–15 age group compared with the youngest age group.

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.

- 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.

- 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.

Tidskriftsartikel (refereegranskat)abstract
- Bibliometric methods were used to examine: (1) research themes in sport and exercise psychology articles published between 2008 and 2011; and (2) the intellectual base of the field of sport and exercise psychology, defined as influential literature being cited in these articles. The dataset consisted of 795 articles from five sport and exercise psychology journals and 345 articles obtained through citation-based extension (n = 1140 articles). A cluster analysis yielded 73 clusters showing themes in sport and exercise psychology research. Principal component analysis was used to identify and analyze relationships between 14 highly cited research areas constituting the intellectual base of sport and exercise psychology. Some main findings were: (1) the identification of many re-emerging themes, (2) research related to motivation seems to be extensive, (3) sport psychology and exercise psychology research share theoretical frameworks to some extent, however (4) differences compared to previous reviews indicate that sport psychology and exercise psychology may be regarded as two distinct research fields, rather than one united field, and (5) isolated research areas were identified indicating potential for research integration. Suggestions for future research are provided. The bibliometric approach presented a broad overview of trends and knowledge base in sport and exercise psychology research.
