Introduction:
Peer victimization (PV) is associated with physical activity (PA) in children and adolescents, potentially through psychological factors such as self-esteem and physical self-concept. However, the underlying mechanisms remain unclear. This study examined the association between PV and PA and the mediating roles of self-esteem and physical self-concept.
Methods:
A total of 1,063 students (mean age = 12.53 ± 1.75 years; grades 5-9) from twelve schools in Taiyuan completed the MPVS, PARS-3, SES, and Physical Self-Concept Scale. Associations and mediation effects were analyzed statistically.
Results:
PV was negatively associated with PA and with self-esteem and physical self-concept (P < 0.05). Self-esteem and physical self-concept were positively related to PA (P < 0.05). Both variables partially mediated the PV-PA relationship, accounting for 51.20% of the total effect.
Discussion:
PV negatively influences PA both directly and indirectly through self-esteem and physical self-concept. Interventions targeting victimization and improving self-related perceptions may help promote physical activity in youth.
