Child maltreatment is a severe public health and social welfare problem in Brazil. In spite of the fact that parenting programs are widely held as a strategy for reducing maltreatment, there is no evidence-based parenting program available for Brazilian families. This project aims to evaluate the efficacy of the Positive Parenting Program (Group Triple P) and cultural acceptability with Brazilian parents. Secondary analyses will also be conducted to examine if parental attributions change during the intervention and if attributions mediate the relationship between intervention exposure and outcomes.

The study will be a randomized controlled trial (RCT) using a group comparison methodology (2x3 design) involving two conditions (Group Triple P intervention vs. Waitlist control group) by three periods of time (baseline, immediately post-intervention and 6 month follow up). Questionnaire batteries will be used to collect data on each of the variables at the three time points. This study can offer unique contribution to understand the effectiveness of a parenting program in a developing country such as Brazil. Collecting information directly from parents can also provide valuable insights to help researchers and family service to consider tailoring or developing a parenting program appropriated and relevant for Brazilian families. In addition, the results of this study may shed light on the processes underlying the effects in parenting programs.


The proposed research project is being funded with the assistance of the student scholarship from the Brazilian Federal Agency CAPES (Coordenação de Aperfeiçoamento de Pessoal de Nível Superior- Coordination for the Improvement of Higher Education Personnel).
