Participants were 350 men and women (Mean age 62.77 years) who were interviewed on their motivations toward PA, perceived level of competence to practice, and PA practice. Cluster analyses reveal the existence of three distinct profiles: "High Combined" (ie, high scores on motivations ranging from intrinsic to external regulation, moderate level on amotivation), "Self-Determined" (ie, high scores on intrinsic, integrated, and identified regulations; low scores on other regulations), and "Moderate" (ie, moderate scores on all regulations). Participants with "High Combined" and "Self-Determined" profiles reported higher perceived competence and longer leisure-time PA practice in comparison to those with a "Moderate" profile. This study highlights the necessity of adopting a person-centered approach to better understand motivation toward PA among type 2 diabetics.

The first purpose of this study was to evaluate if athletes differentiated the reflected appraisals of three significant others: coaches, parents and teammates. The second purpose of this study was to examine the relation between reflected appraisals of those three significant others and athletes' self-perceptions in terms of competence and future progress. Participants were 368 young adult athletes (M age = 21.13). Preliminary analyses indicated that reflected appraisals of coaches and teammates were strongly related, supporting the existence of a "generalized sport-other" (Amorose, 2003). Multiple regression analyses revealed that athletes' self-perceptions of competence were positively predicted by reflected appraisals of sport-others and parents about competence. Moreover, athletes' self-perceptions of future progress were positively predicted by reflected appraisals of sport-others and parents about future progress and by reflected appraisals of parents about competence, but negatively predicted by reflected appraisals of sport-others about competence. Results are discussed in terms of contributions to the understanding of how coaches, teammates and parents specifically shape athletes' self-perceptions.

Study 1 underlines the content validity of a pool of 30 items ( N = 20). Study 2 supports the six-factor structure validity of the 18-item Echelle de Motivation envers l'Activité Physique en contexte de Santé ( N = 309). Study 3 ( N = 191) confirms structure validity, as well as concurrent validity and 2-week temporal reliability. The Echelle de Motivation envers l'Activité Physique en contexte de Santé can be considered as a valid and reliable tool to use in prevention or rehabilitation contexts.

The aim of this study was to identify factors leading teachers (N=336) to report that they create such a climate. We conducted a path analysis in order to examine the respective roles of teachers' implicit theories, their seniority, and their perceptions of pressures at work. We also attempted to find out whether these personal and contextual variables have a direct infiuence or are mediated by teachers' self-efficacy. Our first finding was that a theory of academic ability as a fixed trait caused a drop in the teachers' reported support for autonomy. On the other hand, the belief that academic abilities can be improved through students' own efforts indirectly favored an autonomy supportive climate by acting positively on the teachers' self-efficacy. Also, seniority had a significant positive effect on autonomy support that was direct, but was also mediated by self-efficacy. Finally, perceived pressures had a negative impact on reported autonomy support, but their infiuence was also mediated by self-efficacy.

Standard of competition was examined by studying 30 handball matches, 15 at League and 15 at National standard. At both standards, we examined two types of refereeing decision (sporting and disciplinary) after transgressions that varied in ambiguity. The results indicated that referees made more lenient decisions at higher standards of competition, but this tendency depended on the type of decision being made and ambiguity in the offence. The hypothesis that referees use standard of competition as a judgemental heuristic, but in varying ways, was supported.

According to the behaviour motivation hypothesis, perceived risk could be positively and directly related to PA, but this possibility has been ignored and/or underestimated. Accounting for recent methodological developments on the importance of study design and risk perception assessment, the purpose of the present study was to examine the risk-perceptions-PA relationship among older adults. Participants (N=143) aged from 61 to 70 years initially underwent measurement of risk perceptions, baseline PA, socio-demographic and health factors. Six months later, they were asked about their PA participation. Multiple regression analyses revealed that perceived risk of suffering from diseases and conditions without regular PA participation was an independent positive predictor of later PA, over and beyond baseline behaviour, socio-demographic and health variables. This study fills a gap in the existing literature on the PAs of older adults and reveals that risk perceptions are directly linked to their participation. In addition, it extends existing knowledge in health psychology on the behaviour motivation hypothesis, and emphasises the necessity of methodological adjustments when assessing the risk-perception-behaviour relationship.
