Scientology and its ‘clear’ business

The Church of Scientology (COS) has been the center of controversy and moral panics around the world. Many of its critics, including government and professional bodies suggest that it is a “destructive cult” with values in conflict with society. Against such views, it is argued that the CoS both reflects and relies on conventional values. The CoS is analyzed as a successful commercial enterprise which, seeking to achieve its goals, occasionally adopts illicit means. The CoS's business is also deviant in that it denies its commercial structure. Ironically, it is this very denial, this very deviance that helps explain its survival and success.     

Dimensions of Coaching Behavior, Need Satisfaction, and the Psychological and Physical Welfare of Young Athletes

Grounded in self-determination theory (E. L. Deci & R. M. Ryan, 2000), the purpose of this study was to examine the relationship of dimensions of coaching behavior to intrinsic need satisfaction and indices of psychological and physical well-being among male adolescent athletes. Participants were 265 British soccer and cricket players (M _age = 16.44). Structural equation modeling analysis, using maximum likelihood robust method, showed athletes' perceptions of autonomy support, mastery focus, and social support from the coach to predict their satisfaction of the needs for autonomy, competence, and relatedness, respectively. The satisfaction of the need for competence emerged as the most important predictor of psychological and physical well-being. The findings suggest that particular aspects of the social environment may be salient for fostering particular psychological needs. The results also underline the importance of perceived competence for the psychological and physical welfare of adolescents in team sports.     

A longitudinal examination of coach and peer motivational climates in youth sport: implications for moral attitudes, well-being, and behavioral investment

Embedded in achievement goal theory (Ames, 1992; Meece, Anderman, & Anderman, 2006), this study examined how perceptions of coach and peer motivational climate in youth sport predicted moral attitudes, emotional well-being, and indices of behavioral investment in a sample of British adolescents competing in regional leagues. We adopted a longitudinal perspective, taking measures at the middle and the end of a sport season, as well as at the beginning of the following season. Multilevel modeling analyses showed that perceptions of task-involving peer and coach climates were predictive of more adaptive outcomes than were perceptions of ego-involving peer and coach climates. Predictive effects differed as a function of time and outcome variable under investigation. The results indicate the importance of considering peer influence in addition to coach influence when examining motivational climate in youth sport.     

Self-determination theory and diminished functioning: the role of interpersonal control and psychological need thwarting

Drawing from self-determination theory, three studies explored the social-environmental conditions that satisfy versus thwart psychological needs and, in turn, affect psychological functioning and well-being or ill-being. In cross-sectional Studies 1 and 2, structural equation modeling analyses supported latent factor models in which need satisfaction was predicted by athletes' perceptions of autonomy support, and need thwarting was better predicted by coach control. Athletes' perceptions of need satisfaction predicted positive outcomes associated with sport participation (vitality and positive affect), whereas need thwarting more consistently predicted maladaptive outcomes (disordered eating, burnout, depression, negative affect, and physical symptoms). In addition, athletes' perceptions of psychological need thwarting were significantly associated with perturbed physiological arousal (elevated levels of secretory immunoglobulin A) prior to training. The final study involved the completion of a diary and supported the relations observed in the cross-sectional studies at a daily level. These findings have important implications for the operationalization and measurement of interpersonal styles and psychological needs.

When feeling attractive matters too much to women: A process underpinning the relation between psychological need satisfaction and unhealthy weight control behaviors

This study examined a process model linking psychological need satisfaction to unhealthy weight control behaviors. Female University students (N = 220; M age = 20.47; SD = 5.07) completed questionnaires measuring need satisfaction, appearance-contingent self-worth, weight-related appearance anxiety and unhealthy weight control behaviors. Structural equation modeling revealed that need satisfaction indirectly related to engagement in unhealthy weight control behaviors through appearance-contingent self-worth and weight-related appearance anxiety. The results indicate that appearance-contingent self-worth might help to explain how low levels of psychological need satisfaction are related to maladaptive weight-related outcomes in young women.     

Assumptions in research in sport and exercise psychology

ObjectivesThe aim of this article is to outline how certain key assumptions affect the quality and interpretation of research in quantitative sport and exercise psychology.MethodsA review of three common assumptions made in the sport and exercise psychology literature was conducted. The review focused on three assumptions relating to research validity and the treatment and interpretation of observations. A central theme to this discussion is the assumption that research observations reflect true effects in a population.ResultsAssumptions often made in sport and exercise psychology research were identified in three key areas: (1) validity, (2) inferences of causality, and (3) effect size and the “practical significance” of research findings. Findings indicated that many studies made assumptions about the validity of the self-report psychological measures adopted and few provided a comprehensive evaluation of the validity of these measures. Researchers adopting correlational designs in sport and exercise psychology often infer causality despite such conclusions being based on theory or speculation rather than empirical evidence. Research reports still do not include effect size statistics as standard and confine the discussion of findings to statistical significance alone rather than commenting on “practical significance”.ConclusionResearch quality can only be evaluated with due consideration of the common assumptions that limits empirical investigation in sport and exercise psychology. We offer some practical advice for researchers, reviewers, and journal editors to minimise the impact of these assumptions and enhance the quality of research findings in sport and exercise psychology.
