RI-CLPM = random intercept cross-lagged panel model. SMU = social media use; β = STDYX-standardized. Results in table show the average estimates over 20 imputed datasets of plausible values. All models included (residual) correlations between measurements in the same year. Observed differences between boys and girls were all not significant ( p > 0.05). *** p < 0.001; ** p < 0.01; * p < 0.05.
