Maternal Influences of Substance Use Among Urban Black Male Adolescents

描述(由申请人提供)：在拟议的项目中，我们试图检查城市非裔美国母亲对她们青春期儿子的健康危险行为--烟草、酒精和其他物质使用(TAOS)--发生的影响。该项目的目的是：1)测试城市青少年男性Taos使用行为的家庭影响；2)测试针对城市非裔美国母亲的基于理论的、特定于文化的亲子健康风险降低干预是否有效地改变他们青春期儿子的Taos使用行为；以及3)测试哪些关键的母亲结局变量中介了这些干预效果。这项研究是在以家庭为基础的合理行动理论的扩展范围内进行的，并基于对随机对照研究母子减少艾滋病毒风险干预(R01 MH55742；L.Jemmott)数据的二次分析。最初的研究包括575对非裔美国母亲和她们青春期的儿子(11-15岁)，他们是从宾夕法尼亚州费城的公共住房中招募的。参与者被随机分成两个结构相似的条件之一：a)艾滋病毒风险降低条件；或b)侧重于改变健康和物质使用行为的健康促进/风险减少条件(作为原始研究中的对照组)。在拟议的研究中，将以降低HIV风险的条件作为对照组，并考察健康促进干预对儿子自我报告使用Taos的影响。感兴趣的次要结果和潜在的中介因素包括母亲的意图和实际尝试通过监测、父母-青少年沟通和使用Taos的角色建模来影响她们儿子的行为。数据将使用广义估计方程(GEE)进行分析，并指定与结果变量水平相适应的联系。本文还将使用理论框架和现有文献中的关键变量来检验干预效果的中介作用。通过利用现有数据，拟议的研究将能够回答有关在高危城市青少年男性中使用TAOS对家庭影响的关键问题，而成本仅为进行另一项随机对照试验研究和收集新数据所需费用的一小部分。这些发现将有助于开发有效的以家庭为基础的计划，以减少高危城市、非裔美国青少年男性及其家庭使用TAOS。

DESCRIPTION (provided by applicant): In the proposed project, we seek to examine the influence of urban African American mothers on the occurrence of health risk behaviors -tobacco, alcohol and other substance use (TAOS) - among their adolescent sons. The purposes of the project are to: 1) test family influences of urban adolescent males' TAOS use behaviors; 2) test whether a theory-based, culture-specific, parent-child health risk reduction intervention with urban African American mothers is effective in changing the TAOS use behaviors of their adolescent sons; and 3) test which key maternal outcome variables mediate these intervention effects. The study is framed within a family-based expansion of the Theory of Reasoned Action and based on a secondary analysis of data from a RCT mother-son HIV risk reduction intervention (R01 MH55742; L. Jemmott). The original study included 575 dyads of African American mothers and their adolescent sons (11-15 years), recruited from public housing in Philadelphia, PA. Participants were randomized to one of two structurally similar conditions: a) a HIV risk-reduction condition; or b) a health promotion/risk reduction condition focusing on changing health and substance use behaviors (served as control group in the original study). In the proposed study, the HIV risk reduction condition will serve as the control group and we will examine the effects of the health promotion intervention on sons' self-reported use of TAOS. Secondary outcomes of interest and potential mediators include mothers' intentions and actual attempts to influence their sons' behaviors through monitoring, parent- teen communication and role modeling of TAOS use. Data will be analyzed using generalized estimating equations (GEE), with specification of links that are appropriate to the level of the outcome variable. Mediation of intervention effects will also be examined using key variables from the theoretical framework and the existing literature. By utilizing existing data, the proposed study will be able to answer key questions regarding family influences of TAOS use among high risk urban adolescent males for a fraction of the cost involved in conducting another RCT study and collecting new data. The findings will contribute to the development of effective family-based programs to reduce TAOS use among high-risk urban, African American adolescent males and their families.
