The impact of evidence-based parenting support in the real world

Randomised clinical trials are a necessary step in developing an evidence base to support dissemination of interventions such as a parenting support programs in the community. However, there is a need to explore the effectiveness of such programs once they are offered by services in the real world. This study draws on a database of 6,271 parents completing the evidence-based Group Triple P - Positive Parenting Program in the United Kingdom between 2016 and 2020 in routine service delivery conditions. While improvements in parenting style, parent adjustment and child outcomes are predicted in line with the existing evidence, this study aims to explore whether there are similar effect sizes in community delivery as in controlled trials. It also aims to explore whether there are differential outcomes for boys and girls, children of different ages, and whether clinically significant change in parent variables predicts the magnitude of change in children’s outcomes.
