项目摘要

DESCRIPTION (provided by applicant): The central goal of this study is to examine physiological and emotional reactivity to social and gay- related stressors among sexual minority girls (SMGs; girls who report same-sex attraction, same-sex sexual behavior, and/or a bisexual or lesbian identity), and their prospective associations with substance use and abuse. Minority Stress Theory (MST; Meyer, 2003) asserts that discrimination, violence, and victimization are the primary driving mechanisms of substance use and other mental health disparities among SMGs. Several recent studies published by the proposed PI support this hypothesis. Meta-analysis results showed that compared with heterosexual girls, SMGs were 400% more likely to have used drugs and alcohol (Marshal et al 2008), and trajectory analyses show that this disparity is likely to increase as SMGs transition to young adulthood (Marshal et al 2009, 2012). Two other studies showed that compared with heterosexual girls, SMGs were almost 300% more likely to experience suicidality and over 300% more likely to report being assaulted at school (Friedman, Marshal, et al., 2011; Marshal et al, 2011). This study will recruit 120 adolescent girls ages 14-18 (50% SMGs, 50% African-American) to address the proposed aims. We are proposing a modified minority stress model, asserting that physiological and emotional stress reactivity are important components of the minority stress process, and mediators of the pathway to substance use and other mental health outcomes among SMGs. Our specific aims are to: (1) use ecological momentary assessment (EMA) to document the daily social and gay-related stressors examine the "real time" links between these stressors and substance use, depression, and HIV risk behavior; (2) determine whether SMGs exhibit altered physiological and subjective responses to lab-based social and gay-related stress tasks; and (3) determine whether chronic stress exposure and biomarkers of stress reactivity predict long-term substance use, HIV risk behaviors, and other mental health outcomes. This will be the first study to assess, document, and describe stress reactivity processes among SMGs using lab-based and ecologically valid EMA methodologies. There are no empirically supported substance use interventions for sexual minority youth. Results from this study will accelerate progress towards the development of much needed prevention and intervention programs for SMGs at risk.

描述（由申请人提供）：本研究的中心目标是检查性少数女孩（smg；报告同性吸引，同性性行为和/或双性恋或女同性恋身份的女孩）对社会和同性恋相关压力源的生理和情感反应，以及它们与药物使用和滥用的潜在关联。少数群体压力理论（MST; Meyer, 2003）认为歧视、暴力和受害是造成smg群体中物质使用和其他心理健康差异的主要驱动机制。最近由提议的PI发表的几项研究支持了这一假设。荟萃分析结果显示，与异性恋女孩相比，smg使用毒品和酒精的可能性高出400% (Marshal et al . 2008)，轨迹分析表明，随着smg过渡到青年期，这种差异可能会增加（Marshal et al . 2009, 2012）。另外两项研究表明，与异性恋女孩相比，smg女孩自杀的可能性几乎高出300%，在学校遭受性侵犯的可能性高出300% （Friedman， Marshal等人，2011；Marshal等人，2011）。这项研究将招募
