Note. 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.
