Preventing Drug Use and HIV in Hispanic Adolescents

描述(由申请人提供)： 这项研究建议测试一种以父母为中心的生态发展药物滥用和艾滋病毒预防干预措施对西班牙裔、行为问题青少年及其家庭(Familias Unidas；United Families)的有效性。Familas Unidas针对行为问题、药物滥用和危险性行为的三个风险和保护因素：家庭功能、父母监测和青少年关于毒品和性的社会认知中介。将在基线、6个月、18个月和30个月时评估240名8年级的行为问题青少年及其主要父母的指定样本。参与者将在基线后随机进入以下两种情况之一：Familias Unidas或社区控制。Familas Unidas以前曾在选定的西班牙裔移民青少年及其家庭样本中进行测试，以检查对青少年吸毒和艾滋病毒的风险和保护因素的影响。在两项研究中的第一项中，Familias Unidas被证明相对于无干预控制条件，在增加父母投资和减少青少年行为问题方面是有效的。在第二项研究中，Familias Unidas显示出相对于两种注意力控制条件在减少行为问题和防止行为问题青少年使用药物和危险性行为方面的前景。将使用分层线性建模(HLM)来测试(H1)Familias Unidas随时间减少青少年行为问题的有效性；(H2)Familias Unidas随着时间推移预防青少年吸毒的有效性；以及(H3)Familias Unidas随着时间推移预防青少年危险性行为的有效性。此外，HLM将被用来确定(H1a)家庭联盟对青少年行为问题的影响是否将通过家庭功能来调节；(H2a)家庭联盟对药物使用的影响将部分通过：a)青少年行为问题，b)父母对同伴的监督，c)被定义为同伴药物使用的同伴行为问题，以及d)关于毒品的青少年社会认知媒介；以及(H3a)家庭联盟对危险性行为的影响将部分地通过：a)青少年吸毒，b)父母对同伴的监督，c)被定义为同伴性行为的同伴行为问题，以及d)青少年关于性的社会认知媒介。

DESCRIPTION (provided by applicant): This study proposes to test the efficacy of an ecodevelopmental, parent-centered drug abuse and HIV prevention intervention for Hispanic, behavior problem adolescents and their families (Familias Unidas; United Families). Familias Unidas targets three risk and protective factors for behavior problems, drug abuse and risky sexual behavior: family functioning, parental monitoring, and the adolescents' social cognitive mediators regarding drugs and sex. An indicated sample of 240 behavior problem adolescents attending 8th grade and their primary parent figure will be assessed at Baseline, and at 6-, 18-, and 30- months. Participants will be randomized after baseline into one of two conditions, Familias Unidas or Community Control. Familias Unidas has previously been tested to examine the impact on risk and protective factors for adolescent drug use and HIV in selected samples of Hispanic immigrant adolescents and their families. In the first of two studies, Familias Unidas was shown to be efficacious relative to a no-intervention control condition in increasing parental investment and in reducing adolescent behavior problems. In the second study, Familias Unidas showed promise relative to two attention control conditions in reducing behavior problems and preventing drug use and risky sexual behavior among behavior problem adolescents. Hierarchical Linear Modeling (HLM) will be used to test (H1) the efficacy of Familias Unidas in reducing adolescent behavior problems over time; (H2) the efficacy of Familias Unidas in preventing adolescent drug use over time; and (H3) the efficacy of Familias Unidas in preventing adolescent risky sexual behaviors over time. Additionally HLM will be used to determine whether (H1a) the effect of Familias Unidas on adolescent behavior problems will be mediated by family functioning; (H2a) the effect of Familias Unidas on drug use will be partially mediated by: a) adolescent behavior problems, b) parental monitoring of peers, c) peer behavior problems defined as peer drug use, and d) adolescent social cognitive mediators regarding drugs; and (H3a) the effect of Familias Unidas on risky sexual behavior will be partially mediated by: a) adolescent drug use, b) parental monitoring of peers, c) peer behavior problems defined as peer sexual behavior, and d) adolescent social cognitive mediators regarding sex.
