Prevention science: family evidence-based, adolescents and drug use
Publication . Magalhães, Cátia; Kumpfer, Karol
background - One of major cause of disability is mental illness (WHO, 2013). Evidence-based family programs have been considered one of the most effective methods for reducing mental health and substance abuse disorders in youth. A Cochrane review (Foxcroft et al., 2003) concluded that the Strengthening Families Program (SFP) is one of the most effective substance abuse prevention program and also cost effective. Aim and methods - Determine if the family Portuguese SFP outcomes are as effective as the original SFP. The outcomes were compared using data from Portuguese families (n=41) and SFP international norms using a quasi-experimental, non-equivalent control 2 group pre-and post-test design. Standardized test scales were used. A 2x2 ANOVA produced the outcomes including p-values and effect sizes. Results - According to original SFP norms, statistically significant positive results (p ≤ .05) were found for 16 (or 76.2%) of the 21 outcomes measured and medium to large effect sizes, including family outcomes for Portuguese families. Conclusion - evidence-based family programs are a strong and robust intervention strategy to prevent family risk factors and promote protective factors.
