Effectiviteit van Triple P in Nederland: stand van zaken en controverse

Objective: The Triple P – Positive Parenting Program is available in over 50% of the Dutch municipalities. In this article we summarize the effects of Triple P as found in international meta-analyses and Dutch research. We also discuss the controversy surrounding Triple P. Method: We systematically discuss international meta-analyses and Dutch studies with a control group. Results: According to international research, the effect of Triple P on child behavioural problems and parenting skills is greater than that of care-as-usual. In the Netherlands, Triple P levels 3 and 4 are not more effective than care-as-usual; other levels of Triple P have not been studied. Discussion: Conflict of interest among the developers of Triple P appears to influence the results of international research on Triple P in which they are often involved. Dutch research is performed independently of Triple P developers except for one study) and finds that Triple P is not more effective than care-as-usual
