Parental marital conflict and short video dependency: a moderated mediation model

Objective: This study aims to examine the mediating role of stress and the moderating effect of physical activity (PA) in the relationship between parental marital conflict (PMC) and adolescent short video dependency (SVD). Methods: = 14.22, SD = 1.46). The data encompassed PMC, adolescent SVD, stress levels, and PA. Analytical procedures-ranging from descriptive and correlational summaries to tests of indirect and conditional indirect effects-were executed in SPSS with the PROCESS macro. Results: After controlling for demographic covariates, PMC was significantly and positively associated with adolescent SVD and perceived stress. Mediation analyses further showed that stress significantly mediated the association between PMC and adolescent SVD. In addition, PA significantly and negatively moderated the stress-SVD link, such that the positive association between stress and adolescent SVD was weaker among adolescents with higher levels of PA. Conclusion: These findings clarify how PMC translates into adolescent SVD at the psychological level. Stress was identified as a mediating factor, while PA, as a moderating mechanism, may attenuate the relationship between stress and adolescent SVD.
