- This study sought to identify profiles of individual, social, and perceived neighborhood environmental correlates of physical activity (PA) and to explore differences between the identified profiles in PA. Residents of assisted living facilities (N = 87, M age = 77.57 years) were recruited for the cross-sectional study. Participants reported their perceived support from important others for PA, basic psychological need satisfaction and motivation for PA, and perceived neighborhood environment around the assisted living facilities. Engagement in light PA and moderate-to-vigorous PA was measured by accelerometers over 1 week. We identified three profiles using latent profile analysis: 'low self-determined and minimally supported', 'moderately self-determined and supported', and 'highly self-determined and supported'. Results showed participants in the highly self-determined and supported profile engaged in higher levels of light PA and moderate-to-vigorous PA than participants from other profiles. Findings showed perceptions of the neighborhood environment should be taken into account with motivation regarding PA.

- 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.

- 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.

- 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.

- Bayesian statistics is on the rise in mainstream psychology, but applications in sport and exercise psychology research are scarce. In this article, the foundations of Bayesian analysis are introduced, and we will illustrate how to apply Bayesian structural equation modeling in a sport and exercise psychology setting. More specifically, we contrasted a confirmatory factor analysis on the Sport Motivation Scale II estimated with the most commonly used estimator, maximum likelihood, and a Bayesian approach with weakly informative priors for cross-loadings and correlated residuals. The results indicated that the model with Bayesian estimation and weakly informative priors provided a good fit to the data, whereas the model estimated with a maximum likelihood estimator did not produce a well-fitting model. The reasons for this discrepancy between maximum likelihood and Bayesian estimation are discussed as well as potential advantages and caveats with the Bayesian approach.

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.

Evidence transcranial direct current stimulation can improve saccadic eye movement control in older adults

Tidskriftsartikel (refereegranskat)abstract
- Objectives: Ageing is associated with declines in voluntary eye movement control, which negatively impact the performance of daily activities. Therapies treating saccadic eye movement control deficits are currently lacking. To address the need for an effective therapy to treat age-related deficits in saccadic eye movement control, the current study investigated whether saccadic behaviour in older adults can be improved by anodal transcranial direct current stimulation (tDCS) over the dorsolateral prefrontal cortex using a montage that has been proven to be effective at improving nonoculomotor control functions.Method: The tDCS protocol entailed a 5 cm × 7 cm anodal electrode and an encephalic cathodal reference electrode positioned over the contralateral supraorbital area. In two experiments, healthy older men completed one active (1.5 mA current for 10 min) and one sham stimulation session, with the session order counterbalanced across participants, and eye movement testing following stimulation. In the first experiment, participants rested during the tDCS (offline), whereas in the follow-up experiment, participants engaged in antisaccades during the tDCS (online).Results: Analyses revealed improvements in saccadic performance following active anodal tDCS relative to sham stimulation in the online experiment, but not in the offline experiment, which was presumably due to the activation of the relevant networks during tDCS promoting more targeted effects.Discussion: These outcomes converge with findings pertaining to nonoculomotor cognitive functions, and provide evidence that tDCS can improve saccadic eye movement control in older adults.

Tidskriftsartikel (refereegranskat)abstract
- Past research suggests that athletes' relationships with their coach can act as a risk factor in the development of burnout. Coaching practice may be enhanced through understanding the multidimensional factors that can augment the associations between coach-athlete relationship quality and athlete burnout. The present study explored both individual difference characteristics (gender, age, and sport level) and sociocultural factors (sport type) as moderators of this relationship. Our findings show statistically significant interaction effects for gender and age. Coaches and practitioners working with younger athletes and male performers in particular, are advised to work with strategies aiming to build relationships and reduce the risk of burnout.
