Etiologic mechanisms in an adapted family‐based preventive intervention for underage alcohol use in Mexico: Results of an exploratory pilot study

Alcohol use represents a global health problem, especially for Latin American youth. As part of the Global Smart Drinking Goals campaign, a family‐based preventive intervention was adapted and piloted in Mexico based on an existing evidence‐based program, Guiding Good Choices. In this study, we explored the malleability and session‐specific mean‐level changes in protective and risk factors targeted by the adapted family intervention as related to the prevention of underage alcohol use and abuse. The sample consisted of 177 parents working at four private local companies who had children between the ages of 8 and 16. Data were collected before and after each program session. Linear mixed‐effects models were used to examine growth trajectories and session‐specific mean differences for selected etiologic factors. Significant effects on protective and risk factors were found. Among protective factors, positive family involvement showed the most considerable linear growth over time, while clear standards for youth showed the largest within‐session increase. The greatest linear decrease in risk was observed for family conflict, which also showed the greatest pre‐, and post‐session reduction. Our findings suggest that the adapted program helped families develop protection against, and reduce risk of, alcohol use in their adolescent children. Results from this exploratory pilot study provide support for further rigorous evaluation and dissemination of the adapted intervention for Hispanic families. 摘要 饮酒是一个全球性的健康问题，对拉丁美洲青年尤其如此。作为全球明智饮酒目标运动的一部分，一项基于家庭的预防干预措施在墨西哥进行了调整和试点，依据的是现有的循证项目 “指导良好选择”。在本研究中，我们探讨了文化调适后的家庭干预措施所针对的保护性和风险性因素的可塑性和特定时段的平均水平变化，这些因素与预防未成年酒精使用和滥用有关。该研究的样本包括177名父母，他们在当地四家私营公司工作，子女年龄在8岁至16岁之间。每个项目之前和之后都进行数据收集。研究采纳线性混合效应模型用于检查选定病因因素的生长轨迹和会话特异性平均差异。也找到对保护因素和危险因素均有显著的影响。在保护性因素中，积极的家庭参与随着时间的推移呈现出最显著的线性增长，而明确的青少年标准在会议期间的增长最大。家庭冲突风险的线性下降幅度最大，项目培训前和项目培训会议后的下降幅度也最大。我们的研究结果表明，改编后的项目有助于家庭发展对青少年儿童饮酒的保护，并降低其饮酒风险。这项探索性试点研究的结果为进一步严格评估和推广适合西班牙裔家庭的干预措施提供了支持。
