Boosting happiness in left-behind children: Unveiling the power of physical activity through cognitive reappraisal and psychological resilience.

This study examines the mediating roles of cognitive reappraisal (CR) and psychological resilience (PR) in the relationship between physical activity (PA) and subjective well-being (SWB) among left-behind children in China. A cross-sectional design was employed to collect data from 606 students in grades 4-9. The International Physical Activity Questionnaire Short Form (IPAQ-SF), Positive and Negative Affect Scale (PANAS), Satisfaction with Life Scale (SWLS), Emotion Regulation Questionnaire (ERQ), and Adolescent Resilience Scale were used to collect data. The findings revealed a significant direct effect of PA on SWB and identified CR and PR as significant mediators in this relationship. In particular, the findings indicated that PA was associated with enhanced CR and PR, which in turn, were positively linked to SWB. The study elucidated the chain mediation pathway "PA → CR → PR → SWB," thereby underscoring the pivotal roles of CR and PR in the positive impact of PA on SWB among left-behind children. The findings indicate that PA plays a significant role in the SWB of left-behind children, with CR and PR identified as key mediators in this relationship. The study highlights the necessity of promoting PA, in conjunction with strategies to enhance CR and PR, as efficacious interventions for the enhancement of the mental health and well-being of left-behind children.
