Outline
This study aimed to investigate the effects of childhood trauma, classmate support and school connectedness on psychological distress, thereby providing an empirical basis for developing preventive interventions for mental health problems in adolescents.
A questionnaire survey was conducted among 2 500 middle school students. Multiple linear regression analysis was employed to examine the effects of childhood trauma, classmate support, and school connectedness on psychological distress, and their interactive effects.
The total detection rate of psychological distress was 43.9%, with moderate, and severe cases accounting for 13.5%, and 5.0%, respectively. Childhood trauma positively predicted psychological distress (β=0.271, P<0.05), while classmate support (β=-0.089, P<0.05) and school connectedness (β=-0.260, P<0.05) negatively predicted psychological distress. After including the three-way interaction term (childhood trauma × classmate support × school connectedness), the model’s explanatory power for psychological distress increased by 0.4%(△R2=0.004, P<0.05). Childhood trauma remained a positive predictor of psychological distress(β=0.289, P<0.05), whereas classmate support (β=-0.105, P<0.05), school connectedness (β=-0.282, P<0.05), and the three-way interaction term (β=-0.103, P<0.05) negatively predicted psychological distress. Results of the simple slope analysis showed that there were significant differences between Slope 1 and Slope 3, as well as between Slope 3 and Slope 4(both P<0.05).
The occurrence of psychological distress in middle school students is associated with childhood trauma,classmate support, and school connectedness. Notably, these three factors demonstrate significant interactive effects on students’ psychological distress. Moving forward, greater emphasis should be placed on screening adolescents for childhood trauma experiences while simultaneously addressing peer relationships and school culture.
