Family Matters is a universal intervention designed to prevent adolescent tobacco and alcohol use through involvement of family members and by targeting family risk factors for tobacco and alcohol use. Previously reported findings suggest that the program reduced the prevalence of both adolescent smoking and drinking in the 12 months after program completion. This paper reports analyses conducted to identify the mediators through which the program influenced adolescent smoking and drinking.
One thousand fourteen adolescents ages 12 to 14 years and their families, identified by random-digit dialing, were entered into a randomized trial. Adolescents and their parents provided data by telephone for measuring mediator and behavioral variables at baseline, 3 months, and 12 months after program completion. Repeated-measures logistic regression with generalized estimating equations was used to assess mediation processes.
The program resulted in statistically significant changes in several substance-specific aspects of the family, such as rule setting about tobacco and alcohol use. However, the intermediate family effects did not account for the program effects on adolescent behavior.
The variables hypothesized to explain program effects were not identified by direct empirical examination.
“家庭事务”是一项通用干预措施，旨在通过家庭成员的参与以及针对烟草和酒精使用的家庭风险因素来预防青少年吸烟和饮酒。先前报告的研究结果表明，该项目在完成后的12个月内降低了青少年吸烟和饮酒的发生率。本文报告了为确定该项目影响青少年吸烟和饮酒的中介因素而进行的分析。
通过随机数字拨号识别出1014名12至14岁的青少年及其家庭，并将其纳入一项随机试验。青少年及其父母通过电话提供数据，以测量项目完成后基线、3个月和12个月时的中介变量和行为变量。使用带有广义估计方程的重复测量逻辑回归来评估中介过程。
该项目在家庭的几个特定物质方面产生了具有统计学意义的变化，例如关于烟草和酒精使用的规则设定。然而，家庭的中间效应并不能解释该项目对青少年行为的影响。
通过直接实证检验未发现假设用于解释项目效果的变量。
