Consistent with cognitive-behavioral therapy (CBT) principles, CBPA could provide adolescents with self-regulatory strategies that support mental health. However, the cross-sectional and self-report design, as well as the focus on sports high school students, limit causal inference and generalizability. Future longitudinal and cross-cultural studies are needed to confirm these findings. Overall, the study provides preliminary evidence that CBPA-informed approaches may hold promise for promoting adolescents' mental wellbeing.
