How depression affects school social adaptation: the mediating role of sleep quality and the buffering effect of physical activity

Sleep quality is a crucial mediating mechanism through which depression affects school social adaptation, while physical activity plays a positive moderating role in this process. The findings suggest that encouraging adolescents to engage in regular physical activity may serve as an effective intervention strategy to improve sleep quality, alleviate depressive symptoms, and ultimately enhance their school social adaptation. As a primary goal, the abstract should render the general significance and conceptual advance of the work clearly accessible to a broad readership. References should not be cited in the abstract.
