When given opportunities for personal glory in individual settings, people high in narcissism excel. However, less is known about narcissists' influence in team contexts. Across two studies (utilizing cross-sectional and two-wave longitudinal designs) involving 706 athletes from 68 teams in total, we tested a conceptual model linking narcissism to task cohesion, via intragroup conflict, moderated by narcissistic group composition. We tested a new sports-oriented measure of intragroup conflict using Bayesian estimation and evaluated our theorizing using a multilevel conditional indirect effect hybrid model. Across both studies, we found that narcissism influenced perceptions of task cohesion via process conflict only, with a negative influence at low narcissistic group composition that was weakened (Study 1) or nullified (Study 2) at high narcissistic team composition. Collectively, these findings offer the first example of how narcissism influences task cohesion in team settings and the contextual effects of narcissistic group composition.

Background: Given the limited research on behavioral determinants of using virtual exercise machines to engage in exercise during the COVID-19 pandemic, this study applied an integrated behavior change model to identify behavioral determinants using these machines.

Method: Adult owners of livestreaming virtual exercise equipment (N = 123) completed measures of social cognition, planning, motivation, virtual exercise machine features, and sociostructural variables at an initial occasion (T1) and 4 weeks later (T2). Hypothesized relations among model constructs were tested using a cross-lagged structural equation model with past behavior and sociostructural variables as covariates.

Results: Autonomous motivation predicted intentions and habit indirectly via attitudes and perceived behavioral control at T1; virtual exercise machine features predicted intention and habit indirectly via social cognition constructs at T1; and intention and habit at T1 predicted exercise behavior at T2.

Conclusions: This study supports social cognition constructs and virtual features as predictors of exercise using virtual exercise machines.

This study examined the home advantage effect in decisive National Basketball Association Conference Finals and Finals series playoff games from 1979 to 2019 (the 3-point shot era). We also examined the potential contribution of various offensive- and defensive-based skills and whether these skills mediated the relationship between game status (decisive vs. nondecisive) and outcome (win vs. loss). Overall, we found evidence of a home court advantage with the home team winning 63% of the decisive playoff games and 66% of the nondecisive playoff games. After adjusting for multiple comparisons and regular season win percentage, the home team had significantly more defensive rebounds and steals in Game 5 when trailing 3-1 going into that game. Mediation analyses did not reveal any significant findings when examining the impact of decisive game status on performance through offensive and defensive skills, thus suggesting there are other explanations for the home advantage effect.

Scholars have proposed that cumulative experiences of anti-fat bias and stigma contribute to detrimental physical activity experiences, as well as social and health inequities. The objective of this research was to explore how enacted weight stigma experiences are constructed and impact women's physical activity experiences long term. Eighteen women who identified as having had negative experiences related to their body weight, shape, or size in physical activity contexts participated in semistructured interviews. Using reflexive thematic analysis, four themes were identified: (a) norms of body belonging, (b) distancing from an active identity, (c) at war with the body, and (d) acts of resistance. These findings deepen understandings of how historical experiences of weight stigma can have longstanding consequences on physical activity cognitions, emotions, and behaviors. To equitably promote physical activity, it is imperative that movement spaces (e.g., fitness centers, sport organizations) both target anti-fat stigma and adopt weight-inclusive principles.

The sport team social environment plays an important role in athletes' experiences, including their enjoyment of sport, and these experiences may influence athletes' decision to continue or dropout of sport. In the current study, enjoyment was examined as a mediator of the relationship between social identity and sport dropout. Adolescent girls (N = 150) who participated on a community sports team completed a questionnaire assessing social identity with their team and enjoyment of sport, and their sport participation status was measured 1 year later. Controlling for age and socioeconomic position, a path model showed that enjoyment mediated the relationship between social identity and sport dropout, bootstrapped unstandardized indirect effect = -0.04, 95% confidence interval [-0.08, -0.01]; p < .01. Fostering social identity with one's sport team may contribute to greater enjoyment of sport and reductions in sport dropout in adolescent girls.

Inhibitory control may be vital in elite sport. The authors examined the link between athletic expertise, inhibitory control, and sport performance in a two-part quasi experiment. Inhibitory control was indexed using the Stop-Signal Task, athlete expertise was categorized on literary recommendations, and sport performance was assessed using athlete and coach ratings. Study 1 examined cross-sectional and longitudinal patterns of inhibitory control across athletic expertise. Study 2 investigated whether the inhibitory control-sport performance relationship was moderated by expertise. Study 1 showed that expertise was linked to greater inhibitory control cross-sectionally and longitudinally. Study 2 revealed that expertise was related to superior performance on the Stop-Signal Task and athlete and coach performance ratings, and this relationship was moderated by athletic expertise. Inhibitory control relates to sport performance, increases with greater athlete expertise, and develops longitudinally. Long-term participation in sport may bring about changes in inhibitory control, which may lead to improved sport performance.

The authors investigated the effects of respite-active music (i.e., music used for active recovery in between high-intensity exercise bouts) on psychological and psychophysiological outcomes. Participants (N = 24) made four laboratory visits for a habituation, medium- and fast-tempo music conditions, and a no-music control. A high-intensity interval-training protocol comprising 8 × 60-s exercise bouts at 100% Wmax with 90-s active recovery was administered. Measures were taken at the end of exercise bouts and recovery periods (rating of perceived exertion [RPE], state attention, and core affect) and then upon cessation of the protocol (enjoyment and remembered pleasure). Heart rate was measured throughout. Medium-tempo music enhanced affective valence during exercise and recovery, while both music conditions increased dissociation (only during recovery), enjoyment, and remembered pleasure relative to control. Medium-tempo music lowered RPE relative to control, but the heart rate results were inconclusive. As predicted, medium-tempo music, in particular, had a meaningful effect on a range of psychological outcomes.

The objective of this study was to improve the measurement of physical activity self-efficacy (PASE) in adults with obesity. To accomplish this objective, a latent variable approach was used to explore dimensionality, temporal invariance, and external validity of responses to a newly developed battery of PASE scales. Data (Nbaseline = 461 and N30 days postbaseline = 427) from the Well-Being and Physical Activity Study (ClinicalTrials.gov, identifier: NCT03194854), which deployed the Fun For Wellness intervention, were analyzed. A two-dimensional factor structure explained responses to each PASE scale at baseline. There was strong evidence for at least partial temporal measurement invariance for this two-dimensional structure in each PASE scale. There was mixed evidence that the effectiveness of the Fun For Wellness intervention exerted a direct effect on latent PASE in adults with obesity at 30 days postbaseline (i.e., external validity) of this two-dimensional structure.
