Objectives: The study investigated the moderating role of achievement goals and motivation regulations on the association between self-reported nutritional supplement (NS) use, doping likelihood, and self-reported doping behaviour among competitive athletes.Method: Four hundred and ninety seven competitive team sport athletes (64% males; M age=23.54 years, SD=5.75) completed anonymous questionnaires measuring self-reported use of prohibited substances and licit NS; beliefs about the "gateway" function of NS; achievement goals; and motivational regulations.Results: Hierarchical linear regression analysis showed that self-reported doping was associated (Adjusted R2=33%) with NS use, a stronger belief that NS use acts as a gateway to doping, amotivation, controlled motivation, mastery approach, and performance avoidance goals. Higher likelihood to use doping substances in the future was associated (Adjusted R2=41.7%) with current NS use, stronger belief that NS act as a gateway to doping, autonomous motivation, and performance avoidance goals. A series of moderated regression analyses showed that NS use significantly interacted with mastery approach, mastery avoidance, performance avoidance goals, autonomous motivation controlled motivation, and with amotivation in predicting self-reported doping. Finally, NS use significantly interacted with mastery approach goals, performance avoidance goals, and controlled motivation in predicting future doping likelihood.Conclusions: Achievement goals and motivational regulations are differentially associated with both doping likelihood and self-reported doping, and may account for the observed association between self-reported NS use and doping substances; thus, providing an alternative explanation to the "gateway hypothesis" that emphasizes the role of motivation.

Abstract: Cyberbullying is an emerging form of aggression that utilizes information and communication technologies (ICTs). While cyberbullying incidents attract considerable attention, research on the causes and psychosocial predictors of cyberbullying is still limited. The present study used an integrated theoretical model incorporating empathy, moral disengagement, and social cognitions related to cyberbullying. Structured questionnaires were administered to 355 randomly selected adolescents (M =14.7, SD =1.20). Linear regression analysis showed that social norms, prototype similarity and situational self-efficacy directly predicted cyberbullying expectations. Multiple mediation modelling indicated that normative influences mediated the effects of moral disengagement and affective empathy on cyberbullying expectations. These findings provide valuable information regarding the effect of both distal and proximal risk factors for cyberbullying in adolescence, highlight the relationship between normative processes and moral self-regulation, and set the basis for related educational and preventive interventions.

Anti-doping policies represent a group of regulations and procedures that are applied by anti-doping organizations in order to safeguard sports against doping. Evidence implies that, for anti-doping policies to be effective, they need to be endorsed by athletes. Still, there is scarce evidence on the process through which athletes decide to endorse and support anti-doping policies and the role of anti-doping education. The main objective of the study was to empirically examine a behavioural model of active anti-doping policy support. A self-reported survey with measures of perceived anti-doping legitimacy, social support via expected obedience, perceived trustworthiness and social cognitive variables associated with anti-doping policy support (attitudes, social norms, descriptive norms, perceived behavioural control, regret, and intention) was completed by 1328 competitive athletes in 6 countries (Germany, Greece, Italy, Russia, Serbia, UK). Athletes who live in countries with comprehensive (emphasis on individual development and competency with a focus on sport and personal integrity) anti-doping education (ADE) and had received ADE are more supportive of anti-doping policies than athletes from countries with basic education provision anti-doping education (information type education). Furthermore, athletes who received ADE reported significantly higher levels of perceived legitimacy, trustworthiness, and obedience. The results of the SEM revealed that perceptions of legitimacy had both direct and indirect effects on intentions to support anti-doping policies. The effect of perceptions of legitimacy was mediated by social cognitive variables, which demonstrated strong direct effects on intentions. Importantly, the model was invariant across the countries, although mean differences in several constructs emerged. Anti-doping milieu and education impact athletes' willingness to support anti-doping policies. Interventions targeting legitimacy beliefs and social cognitive variables can be effective in promoting anti-doping policy support in competitive athletes. These interventions should expand beyond anti-doping policy legitimacy and target the specific beliefs (e.g., norms) that are pertinent to policy support in different countries. • Athletes receiving comprehensive ADE are more supportive of anti-doping policies than athletes who haven't received ADE. • Anti-doping education can increase the legitimacy of authorities implementing anti-doping policies. • Perceptions of legitimacy have both direct and indirect effects, through social cognitive variables, on intentions to support anti-doping policies. • The effect of legitimacy perceptions on intentions to support anti-doping policies is invariant across the countries, but mean differences exist.
