Efficacy of the Triple P-Positive Parenting Program on 0-12 year-old Quebec children?s behavior

This study evaluates the impact of the Triple P parenting support program (Primary Care and Group) on 0-12 year-old Quebec children's behavior. A quasi-experimental pretest - post-test design with an active care-as-usual comparison group was used examine program effects. A sample of 384 parents divided into two groups (n Triple P = 291; n comparison = 93) responded to four subscales of the Strengths and Difficulties Questionnaire: emotional symptoms, conduct problems, hyperactivity/inattention, and prosocial behaviors. The dose of inter-vention received by each parent in terms of number of sessions was considered in the analyses. Results indicated that parents in the Triple P group reported larger improvements than parents in the comparison group with respect to conduct problems, hyperactivity/inattention, and prosocial behavior. Both groups reported similar moderate improvements on emotional symptoms. Intervention dose did not contribute to explaining these dif-ferences, beyond the nature of the intervention (Triple P vs care as usual). A follow-up of parents in the Triple P group two to four years after the end of the program (n follow-up = 164) suggested that the effects of Triple P are maintained over time. These results help to broaden the evidence base on the efficacy of this program in a so-ciocultural and linguistic context different from that in which it was developed.
