Concurrent Substance Use and Related Problems among African American Adolescents: A Daily Diary Study and Qualitative Investigation

项目摘要 目前的研究建议检查日常使用大麻和其他物质使用之间的联系 在非洲裔美国青少年中，并确定潜在的机制， 在这个人群中使用。这一提议针对的是费率不成比例增加的新趋势 与白人相比，非裔美国青年使用大麻的比例。我的科学前提是 一项提议是，非裔美国青年中大麻使用的不成比例增加将有助于 这一群体中与物质有关的后果增加，因为大麻的使用与 同时使用酒精和烟草。同时使用药物尤其令人担忧， 因为它与比单一物质使用更严重的长期后果有关 包括心理困扰和犯罪考虑到青少年吸食大麻 和同时使用药物，我提出的项目研究单一和同时使用大麻的模式 及其与青少年物质使用者中物质相关后果的关联。的 目前的研究将采用基于短信的每日日记调查，以社区为基础的样本， 目前的非洲裔美国人和白色物质使用者定量比较大麻的目前模式， 酒精和烟草的使用，以及与特定使用模式相关的后果。我的具体假设 是：1）大麻的使用将与烟草的使用更密切相关，非洲人中没有同时使用大麻的情况。 美国青少年，但与白色青少年的酒精使用更密切相关; 2）比较 大麻只使用，同时使用大麻和其他物质将更密切相关， 非裔美国青少年的影响比白色青少年。我还将对 在非洲裔美国青年的子样本中进行访谈，以确定区分 大麻使用者只从大麻和其他物质的同时使用者。其长期目标是 研究的目的是确定非洲裔美国青少年在物质相关后果的最大风险， 阐明风险背后的机制，以便为预防方案拟订提供信息。

Project Summary The current study proposes to examine associations between daily marijuana use and other substance use among African American adolescents, and to identify potential mechanisms underlying concurrent substance use among this population. This proposal addresses the emerging trend of disproportionate increases in rates of marijuana use among African American youth relative to those of Whites. The scientific premise of my proposal is that the disproportionate increases in marijuana use among African American youth will contribute to increased substance-related consequences among this group because marijuana use is strongly associated with concurrent use of alcohol and tobacco. Concurrent substance use is particularly concerning among adolescents because it is associated with more severe long-term consequences than single substance use including psychological distress and delinquency. Given the relationship between adolescent marijuana use and concurrent substance use, my proposed project examines patterns of single and concurrent marijuana use and their association with substance-related consequences among adolescent substance users by race. The current study will employ text-message-based daily diary surveys among a community-based sample of current African American and White substance users to quantitatively compare current patterns of marijuana, alcohol and tobacco use, and consequences associated with specific patterns of use. My specific hypotheses are: 1) marijuana use will be more strongly associated with tobacco use and no concurrent use among African American adolescents, but more strongly associated with alcohol use among white adolescents; 2) compared to marijuana only use, concurrent use of marijuana and other substances will be more strongly related to consequences among African American adolescents than White adolescents. I will also conduct qualitative interviews among a subsample of African American youth to identify potential mechanisms that differentiate users of marijuana only from concurrent users of marijuana and other substances. The long-term goal of this research is to identify African American adolescents at greatest risk for substance-related consequences and illuminate mechanisms underlying risk in order to inform prevention programming.
