To investigate the relationship between sports participation and sport trait confidence, 1659 teenagers in primary and secondary schools who regularly play football were asked to complete the Sports Participation Scale, Collective Self-Esteem Scale, Self-Esteem Scale, and Sport Trait Confidence Scale. The results show that (1) the positive prediction of football participation on sport trait confidence is not significant; (2) collective self-esteem and self-esteem play a mediating role between football participation and sport trait confidence; (3) the mediating effect occurs through three pathways. The study provides theoretical guidance and empirical evidence for the lead and intervention of adolescent football participation on sport trait confidence. This study created a chain-mediated model to examine the mediating role of collective self-esteem and self-esteem in their relationship, as well as the impact of the two as chain mediators on football participation and sport trait confidence.

This study was carried out to explore the mechanism between athlete participation and team cohesion for adolescent school soccer players. We examined the mediating role of athlete engagement and collective self-esteem between athlete participation and team cohesion for adolescent soccer players. A comprehensive investigation of 1659 primary and middle school soccer players was conducted using the Athlete Participation Scale, Athlete Engagement Questionnaire, Collective Self-Esteem Scale, and Team Cohesion Scale, and we conducted correlation, regression and pathway analyses among the variables. We found the following for adolescent soccer players: (1) Athlete engagement plays a complete mediating role between athlete participation and team cohesion. (2) Collective self-esteem plays a complete mediating role between athlete participation and team cohesion. (3) Athlete participation does not directly predict team cohesion, but can influence team cohesion through the chain mediation of athlete engagement and collective self-esteem. This study built a chain mediation model showing that athlete engagement and team cohesion mediated athlete participation and team cohesion, to investigate its mediating role for adolescent soccer players. This study provides theoretical guidance and an empirical basis for the intervention of athlete participation on team cohesion in soccer sports among adolescents.

Based on the Conservation of Resources Theory, the research explored the relationships between social support and the psychological well-being of pre-service teachers. It specifically examined the mediating effects of professional identity and the moderating impact of emotional intelligence. A cross-sectional survey was conducted using the Perceived Social Support Questionnaire, Teachers’ Professional Identity Scale, Emotional Intelligence Scale, and Flourishing Scale with a sample of 457 (68.10% were female, and 31.90% were male) pre-service teachers in Shaanxi. The results showed that (1) social support of pre-service teachers had a positive and direct effect on psychological well-being; (2) professional identity mediated the positive association between social support and psychological well-being; (3) emotional intelligence moderated the first-stage path of the indirect effect through professional identity. These findings elucidate the role of external resources (social support) and internal resources (professional identity and emotional intelligence) in pre-service teachers, and suggest that comprehensive and holistic intervention programs may be enhancing psychological well-being among pre-service teachers.
