PARENTING PROGRAMS AND CHILD PROBLEM SEVERITY : Are Group-based Parenting Programs to Prevent Child Problem Behaviors Equally Effective for Children with Clinical and Non-clinical Problem Levels?

The effectiveness of parenting programs in preventing child problem behaviors have been increasingly supported in the literature. However, studies revealed contradictory findings of how children with severe problem levels benefit from the programs. In this study, I performed secondary analysis on parent-reported externalizing behaviors, ADHD and ODD symptoms of 749 children, aged 3-12 years, to evaluate the effectiveness of four different parenting programs on children with clinical and non-clinical problems. Mixed design ANOVA models revealed that the programs significantly reduced children’s externalizing behaviors, ADHD and ODD symptoms at post-test. Furthermore, the same mixed design ANOVA models and follow-up tests revealed consistent significant differences in program response for children with and without initial clinical problems on all outcomes. Cohen’s d within-group change effect sizes showed consistently large program effects for children with clinical problem levels on all outcomes. Findings indicate that group-based parenting programs are effective for children with externalizing behavior, ADHD and ODD symptoms, at least in the short term, and that children with clinical problem levels may benefit substantially
