Adolescent HIV Risk: Links with Unsupportive Parenting and Maladaptive Coping

描述（由申请人提供）：青少年和年轻人比其他任何年龄组的人都要多（CDC, 2008； UNICEF， UNAIDS, & WHO, 2002）。青少年的高冒险行为率可能是这一年龄组艾滋病病毒高发病率的一个解释。特别是，不安全的性行为和药物使用是青少年经常从事的两类行为，这些行为增加了他们感染艾滋病毒的风险（CDC, 2010; Kotchick, Shaffer, Miller, & Forehand, 2001； Stein等，2000;Tapert, Aarons, Sedlar, & Brown, 2001; Temple & Leigh, 1992）。进一步了解与青少年参与这些危险行为有关的前体和机制，对于降低年轻人的感染率至关重要，因此具有重要的公共卫生意义。

DESCRIPTION (provided by applicant): Adolescents and young adults account for more new HIV infections than individuals in any other age group (CDC, 2008; UNICEF, UNAIDS, & WHO, 2002). High rates of risk-taking behavior among adolescents may be one explanation for the high incidence of HIV in this age group. In particular, unsafe sexual practices and substance use are two classes of behaviors in which adolescents frequently engage, and these behaviors place them at increased risk for HIV infection (CDC, 2010; Kotchick, Shaffer, Miller, & Forehand, 2001; Stein et al., 2000; Tapert, Aarons, Sedlar, & Brown, 2001; Temple & Leigh, 1992). Advancing understanding of the precursors and mechanisms related to adolescent engagement in these risky behaviors is crucial to reducing rates of infection among young people and, thus, has important public health implications. Converging evidence indicates that family variables and the manner in which individuals cope with distress and regulate emotions are important predictors of adolescent HIV risk behaviors (Brooks, Harris, Thrall, & Woods, 2002; Cooper, Russell, Skinner, Frone, & Mudar, 1992; DiClemente et al., 2001a, 2001b; Fromme & Rivet, 1994; Jaccard, Dittus, & Gordon, 1996; Perrino, Gonz¿lez-Soldevilla, Pantin, & Szapocznik, 2000). The goal of the proposed study is to further examine the link between parenting variables and adolescent HIV risk behaviors and to explore adolescents' strategies for coping with distress as a mechanism underlying this link. Specifically, the proposed study will examine the relations among parental responses to adolescents' negative emotions, adolescent suppression of distressing thoughts and emotions as a means of coping, and adolescent HIV risk behaviors-both concurrently and over time-using a multi-method study design that will include self-report, psychophysiological, and laboratory task data. [These data from adolescents (15-19 years old) and their parent(s) will be used to address three study aims: (1) To examine the concurrent link between parental responses to adolescents' negative emotions and adolescent HIV risk behaviors, and test whether adolescents' tendency to use suppression of distressing thoughts and emotions as a coping strategy mediates this link; (2) to examine the concurrent link between the suppression of distressing thoughts and emotions and adolescent HIV risk behavior, and test whether physiological arousal mediates this link; and (3) to examine the longitudinal link between parental responses to adolescents' negative emotions and adolescent HIV risk behaviors, and test whether adolescents' tendency to use suppression of distressing thoughts and emotions as a coping strategy mediates this link.] Results from the proposed study will be discussed in terms of their applicability to HIV prevention programs and their impact on public health. PUBLIC HEALTH RELEVANCE: Despite major advancements in HIV prevention efforts in recent years, HIV/AIDS remains a global epidemic and a major public health concern (Joint United Nations Programme on HIV/AIDS, 2010). Adolescents and young adults account for more new HIV infections than individuals in any other age group- 34% of new HIV cases in the United States and over 50% of new cases globally (CDC, 2008; UNICEF, UNAIDS, & WHO, 2002). The proposed project aims to inform HIV prevention efforts by advancing understanding of the precursors and mechanisms related to adolescent engagement in behaviors that place them at both direct (e.g., unsafe sexual practices) and indirect (e.g., substance use) risk for HIV infection and, thus, has important public health implications.
