The present study evaluated two primary care parenting interventions. First, we evaluated the most widely used Dutch practices for primary care parenting support. Second, we assessed the applicability of the Primary Care Triple P approach, which is now being utilized in a wide variety of primary care settings. Both interventions target parents of children with mild to moderate behavioural and/or emotional problems, with the aim of improving parenting skills and thereby decreasing child problems. We examined the interventions in pre-, post- and follow-up assessment, and compared the results. Both interventions produced significant reductions in reported child emotional and behaviour problems, that also remained after 3 months. For both groups, parenting styles were also found to have improved at both post-test and follow-up measurement. When compared with the regular Dutch parenting consultation practices, however, the Primary Care Triple P approach produced greater reductions in parental laxness and total parenting dysfunction, and greater improvement in total parenting competence at both post-test and follow-up. Primary Care Triple P may even--in light of the greater improvements in parenting skills and total parental competences in the Triple P group than in the regular Dutch parenting consultation group--produce better results in the long run concerning child behaviour and emotional problems.
