To test a computer-delivered program for preventing substance use among adolescent girls.
Randomly, 916 girls aged 12.76+/-1.0 years and their mothers were assigned to an intervention arm or to a test-only control arm. Intervention-arm dyads engaged in exercises to improve the mother-daughter relationship, build girls' substance use prevention skills, and reduce associated risk factors. Study outcomes were girls' and mothers' substance use and mediator variables related to girls' substance use risk and protective factors. The study was conducted between September 2006 and February 2009 with participants from greater New York City, including southern Connecticut and eastern New Jersey.
At 2-year follow-up and relative to control-arm girls, intervention-arm girls reported lower relevant risk factors and higher protective factors as well as less past 30-day use of alcohol (p<0.006), marijuana (p<0.016), illicit prescription drugs (p<0.03), and inhalants (p<0.024). Intervention-arm mothers showed more positive 2-year outcomes than control-arm mothers on variables linked with reduced risks of substance use among their daughters, and mothers reported lower rates of weekly alcohol consumption (p<0.0001).
A computer-delivered prevention program for adolescent girls and their mothers was effective in changing girls' risk and protective factors and girls' and mothers' substance use behavior.
测试一个针对少女预防物质使用的计算机程序。
随机将 916 名年龄在 12.76 岁±1.0 岁的少女及其母亲分配到干预组或仅测试对照组。干预组的母女参与了改善母女关系、培养少女预防物质使用技能以及减少相关风险因素的练习。研究结果是少女和母亲的物质使用情况以及与少女物质使用风险和保护因素相关的中介变量。该研究于 2006 年 9 月至 2009 年 2 月进行，参与者来自大纽约市地区，包括康涅狄格州南部和新泽西州东部。
在 2 年的随访中，与对照组的少女相比，干预组的少女报告了较低的相关风险因素和较高的保护因素，以及较少的过去 30 天内使用酒精（p<0.006）、大麻（p<0.016）、非法处方药物（p<0.03）和吸入剂（p<0.024）。与女儿物质使用风险降低相关的变量上，干预组的母亲在 2 年内表现出比对照组母亲更多的积极结果，而且母亲报告每周饮酒量较低（p<0.0001）。
针对少女及其母亲的计算机预防计划有效地改变了少女的风险和保护因素以及少女和母亲的物质使用行为。
