Effects of a personalized PERMA-based intervention on the mental health of junior high school students: a randomized clinical trial

This study provides empirical evidence for the effectiveness of personalized PPIs in addressing adolescents' mental health challenges, with notable improvements in well-being and resilience. Limitations include the small sample size for paired analysis (<i>n</i> = 58) and the timing of the intervention during the final exam period, which might have introduced biases. Future research should explore the sustained effects of such interventions and their scalability across diverse educational settings.
