Identity & Context in HIV Prevention for Hispanic Youth

描述（由申请人提供）： 这项拟议的研究将被用作跳板施瓦茨博士启动艾滋病毒预防研究的职业生涯，重点是自我和背景对西班牙裔青少年艾滋病毒风险行为（物质使用和不安全的性行为）的联合影响。拟议的研究有三个目标。首先，它将为Seth Schwartz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、预防性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-验证性研究进行组织，使用两个单独的样本。这项研究将被用来确定是否个人和种族认同的发展，有助于艾滋病毒的危险行为以上的生态发展变量所作的贡献。三个具体的假设将进行测试：（a）随着时间的推移，生态发展变量的变化预测随着时间的推移，个人和身份的发展变化;（B）个人和种族身份的发展（无论是在总量上还是在生态发展过程无法解释的变异性方面）将预测物质使用、行为问题和不安全性行为的发展;和（c）Familias Unidas的干预显着影响原始的个人和种族认同分数随着时间的推移，但干预不影响这些分数，一旦方差归因于生态发展的预测因素是因素。 第三，假设是支持个人和/或种族认同，个人和/或身份发展的组成部分将被设计为补充的干预策略中使用的Familias Unidas，一个以家庭为基础的预防计划，旨在防止物质使用和不安全的性行为在西班牙裔移民青少年。

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.
