摘要

Problematic social media use (PSMU) has been linked to poorer adolescent health, but evidence on the buffering role of family support is mixed. Using data from the 2017/2018 Greek HBSC study (N = 3,482; ages 11–15), we applied the conceptual model proposed by Ledel et al. (2025) in a Mediterranean setting by examining associations between PSMU and poor self-rated health (SRH), and whether family support modifies this association. Logistic regressions estimated odds ratios (ORs) adjusting for age, gender, and family affluence; clustering by class was addressed with robust standard errors. Compared with low risk, moderate risk and PSMU were associated with higher odds of poor SRH (adjusted trend p<0.001). Adding family support attenuated but did not remove the association. The multiplicative PSMU×family-support interaction was not significant (Wald p = 0.198). Joint-exposure estimates suggested a graded buffering pattern: within low family support, PSMU showed the strongest association with poor SRH; corresponding ORs were smaller at higher support levels. Additive interaction indices (RERI, AP) were not statistically significant. Findings reinforce PSMU as a correlate of poorer SRH and suggest that supportive family contexts may mitigate risk, though formal interaction was not detected. This conceptual replication of Ledel et al. (2025) in a Mediterranean setting highlights family-centered components for digital-well-being initiatives.
