depressive symptoms
Demographic and outcome data collected at baseline will be reported either as means with standard deviation or as frequencies with percentages according to their levels of measurement as a whole sample and by groups. Generalized estimating equations (GEE) will be employed to separately test the hypothesis on the five outcomes as dependent variables (i.e., mental well-being, depressive symptoms, loneliness, health-related quality of life, and perceived social support), The independent variables will be the same across all GEEs: the group (two categories: intervention and control groups), the timepoint (two categories: T0 and T1), and the interaction term (i.e., group × timepoint). The primary interpretation of the results will be based on the intention-to-treat analysis without adjusting for covariates [
