RI-CLPM = random intercept cross-lagged panel model. SMU = social media use; β = STDYX-standardized; SE = standard error. Results in table show the average estimates over 20 imputed datasets of plausible values. All models included (residual) correlations betweenmeasurements in the same year (estimates presented in Table A6.3). *** p < 0.001; ** p < 0.01; * p < 0.05.
