The Brazilian adaptation of the Strengthening Families Program (SFP), known as Famílias Fortes (FF-BR 10-14), has demonstrated positive short-term effects on parental behavior. This study aims to evaluate the 12- and 24-month follow-ups of the FF-BR 10-14, focusing on parental outcomes and substance use prevention.
This is a parallel-cluster randomized controlled trial (RCT) involving 1610 participants (805 adolescents aged 10-14 and 805 caregivers). Conducted across 60 Social Assistance Reference Centers (SARC) in 12 municipalities in Brazil, the trial evaluates the effectiveness of the FF-BR 10-14 program. This study presents data collected at three time points: baseline, 12 and 24 months of follow-up. Multilevel mixed-effects models assessed the program effects on parental and adolescent outcomes (drug use and family behavior), with adjustments for sociodemographic factors.
The results reveal no statistically significant differences between the groups in terms of adolescent drug use after either follow-up. However, participating in the program shows a reduction in negligent parental style (aOR 0.46, 95%CI 0.22;0.97), parental binge drinking (aOR 0.24, 95%CI 0.08; 0.74), as well as an increase in parental ability to set clear rules regarding their children's drug use (β 0.43, 95%CI 0.03; 0.83) and an improvement in adolescents' skills to resolve family conflicts (β 0.79, 95%CI 0.11; 1.46) and to manage stress (β 0.65, 95%CI 0.16; 1.15).
The Famílias Fortes program shows positive effects on mediators, such as parenting practices and adolescent coping skills, but not on the primary outcomes of adolescent substance use. These findings highlight the program's role in improving the family environment and supporting prevention efforts through intermediary behaviors.
The study was registered in the Brazilian Ministry of Health Register of Clinical Trials (REBEC), under protocol no. RBR-5hz9g6z ( https://ensaiosclinicos.gov.br/rg/RBR-5hz9g6z ) - July 8th, 2022.
巴西对强化家庭计划（SFP）的改编版，即“坚强家庭”（FF-BR 10 - 14），已显示出对父母行为有积极的短期影响。本研究旨在评估FF-BR 10 - 14计划在12个月和24个月时的随访情况，重点关注父母相关结果及物质使用预防。
这是一项平行整群随机对照试验（RCT），涉及1610名参与者（805名10 - 14岁青少年和805名照料者）。该试验在巴西12个城市的60个社会援助参考中心（SARC）开展，评估FF-BR 10 - 14计划的有效性。本研究展示了在三个时间点收集的数据：基线、随访12个月和24个月时。多水平混合效应模型评估了该计划对父母及青少年相关结果（药物使用和家庭行为）的影响，并对社会人口学因素进行了调整。
结果显示，在两次随访后，两组在青少年药物使用方面无统计学显著差异。然而，参与该计划显示出疏忽型父母教养方式有所减少（调整后比值比[aOR]为0.46，95%置信区间[CI]为0.22；0.97），父母酗酒情况有所减少（aOR为0.24，95%CI为0.08；0.74），同时父母在为子女药物使用设定明确规则方面的能力有所提高（β为0.43，95%CI为0.03；0.83），青少年解决家庭冲突的技能（β为0.79，95%CI为0.11；1.46）和应对压力的能力（β为0.65，95%CI为0.16；1.15）也有所改善。
“坚强家庭”计划对中介因素，如养育方式和青少年应对技能，显示出积极影响，但对青少年物质使用这一主要结果没有影响。这些发现凸显了该计划在改善家庭环境以及通过中间行为支持预防工作方面的作用。
该研究已在巴西卫生部临床试验注册系统（REBEC）注册，注册号为RBR-5hz9g6z（https://ensaiosclinicos.gov.br/rg/RBR-5hz9g6z）——2022年7月8日。
