Triple P is a parenting programme used in the youth healthcare practice of many Dutch municipalities to support parents in raising their children. According to international research, this Australian intervention is effective for parents with children up to the age of 12. It shows positive effects on parenting skills and on the reduction of both parents' child-rearing stress and their children's behavioural and emotional problems. Our study examined the effectiveness of Teen Triple P level 4: a training programme for parents of teenagers aged 10–16. The programme included five group sessions of 1.5–2 h each, as well as three individual (phone) consultations. Through a matching procedure, 103 parents who participated in Teen Triple P were compared in a quasi-experimental study with 397 parents in a control group. Compared with the control group, parents who received the Teen Triple P training reported a significant improvement in their parental practice. Now, they are more involved with their child, more responsive to the needs of the children, and they report fewer parent–child conflicts. Some positive differences in behavioural problems among adolescents, as reported by their parents, could be found among the experimental group. These findings remained the same at the follow-up.

This paper describes a pilot study to evaluate the effectiveness of a school-based parenting programme combining the use of both affective (related to feelings) and behavioural strategies. In this paper we describe the intervention, its evaluation and a summary of the quantitative information gathered. The three pre-eminent ways in which parents appeared to have benefited from this particular programme included (1) the support they received in their parenting role from other parents, including a mirroring of problems, (2) the regaining of a sense of control in the parental role, in part through an increase in their capacity to think about matters calmly, and also through the provision of new tools with which to do the job of parenting, and (3) an increased ability to empathize and identify with their children, and a better understanding of the factors which motivate children to behave in particular ways. The capacity to think about matters calmly and the ability to empathize and identify with children appeared to be important factors in the reduction of inappropriate and unhelpful parenting practices such as shouting and smacking. It is suggested that empathy in particular is central to effective parenting, and that these results support the suggestion that there is an important added benefit for parents from programmes which combine behavioural and affective strategies focusing on feelings, relationships within the family, and the parents' own experience of being parented. The limitations of the data are discussed with reference to its reliability and validity, and the need for further research using grounded theory with other groups of parents.

The aim of the study was to see whether there were lasting effects of a behaviourally-based group parenting programme when delivered in a real life, regular clinical practice setting. Follow-up was one year after the end of a controlled trial that involved four local child and adolescent mental health services in London and Southern England. The participants were fifty-nine children aged 3–8 years referred with antisocial behaviour, whose parents received the Webster-Stratton Incredible Years basic videotape group programme. Those in the waiting list control group were not followed up as some went on to receive the same intervention. Measures included the semi-structured parent interview (PACS) and questionnaire (SDQ) about child behaviour. At follow-up, the original improvement in the intervention group was found to have persisted, with no loss of treatment effectiveness (effect size compared to pre-treatment score 0.91 standard deviations, compared to post treatment score −0.06 SD). The proportion of children in the clinical range before treatment was 68%, at follow-up 37%. Children with the most severe initial problems changed the most; risk factors such as low income, being a lone parent, or being in an ethnic minority did not reduce treatment effectiveness. Parenting groups can reduce serious child antisocial behaviour effectively in the longer term. This is an important ongoing benefit for the children and their families. If this trajectory continues to be maintained in the future, then the poor long-term prognosis, which includes criminality and social exclusion, is likely to be improved.
