Note: Means (M), standard deviations (SD), intra-group effect sizes (ES), and inter-group effect sizes (IGES) for intervention (I) and control group (CG) for pre, post, 1- and 2-year Follow-up (FU). Sample sizes: I = 28, CG = 31. PPQ = Positive Parenting Questionnaire, higher scores indicate higher amount of positive parenting; PS = Parenting Scale, higher scores indicate higher dysfunctional parenting.
