Identity & Context in HIV Prevention for Hispanic Youth

描述(由申请人提供)： 这项拟议中的研究将被作为施瓦茨博士开始从事艾滋病毒预防研究的跳板，重点关注自我和环境对拉美裔青少年艾滋病毒危险行为(药物使用和不安全性行为)的联合影响。拟议的研究有三个目标。首先，它将为赛斯·施瓦茨博士提供宝贵的指导经验。作为拟议研究的一部分，施瓦茨博士将在家庭研究、纵向研究方法、预防干预设计和实施以及高级统计分析方面接受指导。 职业发展将围绕探索性-验证性研究进行，使用两个不同的样本。这项研究将被用来确定个人和种族认同感的发展是否对艾滋病毒危险行为的贡献超过了生态发育变量的贡献。将检验三个具体假设：(A)生态发展变量随时间的变化预测个人和身份发展随时间的变化；(B)个人和种族认同的发展(总体上和生态发展过程无法解释的变异性)将预测药物使用、行为问题和不安全性行为的发展；(C)Familias Unidas干预措施随着时间的推移显著影响个人和种族认同的原始得分，但一旦剔除可归因于生态发展预测因素的差异，干预不会影响这些得分。 第三，如果个人和/或种族认同的假设得到支持，个人和/或身份发展部分将被设计为补充家庭联盟所使用的干预战略，家庭联盟是一项以家庭为基础的预防计划，旨在防止拉美裔移民青少年使用药物和不安全的性行为。

DESCRIPTION (provided by applicant): The proposed study will be used as a springboard for Dr. Schwartz to launch a career in HIV prevention research focusing on the joint effects of self and context on HIV risk behaviors (substance use and unsafe sexual behavior) in Hispanic adolescents. The proposed study has three objectives. First, it will provide Dr. Seth Schwartz with valuable mentored experiences. As part of the proposed study, Dr. Schwartz will be mentored in family research, longitudinal research methods, preventive intervention design and implementation, and advanced statistical analyses. Career development will be organized around an exploratory-confirmatory study, using two separate samples. This study will be used to ascertain whether the development of personal and ethnic identity contributes to HIV risk behaviors over and above the contributions made by ecodevelopmental variables. Three specific hypotheses will be tested: (a) changes in ecodevelopmental variables over time predict changes in personal and identity development over time; (b) the development of personal and ethnic identity (both in total and in terms of variability not explained by ecodevelopmental processes) will predict the development of substance use, conduct problems, and unsafe sexual behavior over time; and (c) the Familias Unidas intervention significantly influences the raw personal and ethnic identity scores over time, but the intervention does not influence these scores once variance attributable to ecodevelopmental predictors is factored out. Third, provided that the hypotheses are supported for personal and/or ethnic identity, personal and/or identity development components will be designed to complement the intervention strategies used in Familias Unidas, a family-based prevention program designed to prevent substance use and unsafe sexual behavior in Hispanic immigrant adolescents.
