Feasibility of the Strengthening Families Program for Brazilian Families: A Mixed Method Study

Abstract The objective of this study was to examine the feasibility (limited effectiveness, acceptability and practicality) of the Strengthening Families Program, a universal preventive intervention, for Brazilian families. A pre-experimental study was carried out, with pre-test, post-test, 6- and 10-12-month follow-ups. 74 adolescents and their parents participated. Scales on academic, parenting, and health outcomes were applied to adolescents at the four assessment times. Direct observation of implementation fidelity and families engagement in the intervention and telephone interviews with facilitators were used to investigate acceptability and practicality. The results show significant increase in parental supervision and learning self-efficacy. High levels of fidelity and parent/guardian engagement as well as moderate levels of adolescent engagement were found. The facilitators found the intervention had acceptable goals, but procedures excessively structured and unsuitable for families with low educational level. Practical implications are discussed.
