This study aims to evaluate the effectiveness of school-based psychological interventions in improving stress resilience and coping skills among adolescents in rural China. The intervention seeks to reduce stress-related mental health symptoms, including depression, anxiety, and post-traumatic stress, measured using validated instruments such as the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder 7-item scale (GAD-7), and the Child PTSD Symptom Scale for DSM-5 (CPSS-5). (See Appendix for full scale descriptions.) Participants will be recruited from rural middle schools and randomly assigned to either an intervention group or a wait-list control group. The intervention consists of four sessions delivered over one week. Assessments will be conducted at baseline, immediately after the intervention, and again at a 3-month and 6-month follow-ups. Researchers will use multilevel modeling (MLM) and structural equation modeling (SEM) to examine potential mediators and moderators of intervention effects, including emotion recognition, alexithymia, and coping strategies. indings are expected to provide evidence on the effectiveness and mechanisms of an existing, school-based psychological intervention tailored to the needs of adolescents in underserved rural settings.
