  1. 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: mothers: I = 155, CG = 61; fathers: I = 141, CG = 57. PPQ = Positive Parenting Questionnaire, higher scores indicate higher amount of positive parenting; PS = Parenting Scale, higher scores indicate higher dysfunctional parenting.
