  1. Note. Supportive and negative interactions with mothers were reported by mothers. All other variables were reported by youths themselves. In Step 3, all interaction effects were added to the model separately. Main effects in Step 3 were in this table only reported from the model with the interaction effect Age × Supportive Interactions Mother, because these main effects did not differ substantially across the models with interaction effects. Abbreviations: B = Unstandardized beta, SE = Standard error for the unstandardized beta, β = Beta, P = Propability, R2 = proportion of explained variance
