Adolescents often engage in concurrent sexual partnerships as part of a developmental process of gaining experience with sexuality. The authors qualitatively examined patterns of concurrency and variation in normative and motivational influences on this pattern of sexual partnering among African American adolescents (31 males; 20 females), ages 15 to 17 years. Using content analysis, gender and contextual differences in social norms and motivations for concurrency were explored. Findings describe the normative influences on adolescent males and females with regard to sexual concurrency and the transfer of these norms from one generation to the next.  相似文献

This study of 535 older married couples examined the relationship between depression and health and sexual satisfaction directly and when mediated by communication. The sample included 535 older couples who completed a survey questionnaire known as Project Couple Retire. Among the items in the questionnaire were measures of depression, health, perception of sexual intimacy, communication and other demographic information. Results from Structural Equation Modeling indicated that for women, health was a significant predictor of sexual satisfaction. For both genders, the results suggest that depression, when mediated by communication, is a predictor of sexual satisfaction among older couples. Implications for clinicians are discussed.  相似文献

This study examines the role of acculturation, perceived discrimination, and self-esteem in predicting the mental health symptoms and risk behaviors among 1.5 and second generation non-Jewish adolescents born to migrant families compared with native-born Jewish Israeli adolescents in Israel. Participants included n = 65 1.5 migrant adolescents, n = 60 second generation migrant adolescents, and n = 146 age, gender, and socioeconomic matched sample of native-born Jewish Israelis. Participants completed measures of acculturation pattern, perceived discrimination, and self-esteem as well as measures of mental health symptoms and risk behaviors. Results show that migrant adolescents across generations reported worse mental health symptoms compared with native-born Jewish Israelis. However, only the 1.5 generation migrants reported higher engagement in risk behaviors compared with second generation migrants and native-born Jewish Israelis. Our findings further showed that acculturation plays an important role in predicting the mental health status of migrant youth, with those characterized with integrated acculturative pattern reporting lower mental health symptoms compared with assimilated acculturation pattern. Importantly, contextual factors, such as higher perception of discrimination in the receiving culture as well as individual factors such as lower self-esteem and female gender were strongly associated with worse mental health symptoms. The findings manifest the complex relationship between contextual factors and individual level variables in the acculturative process of migrants as well as the importance of examining the effect of migration generation on mental health outcomes.  相似文献

Objectives: To compare the impact of appearance versus health-framed messages on engagement in a brief web-based risk screening and alcohol reduction intervention.

Design: Randomised trial delivered via Drinkaware’s website. Visitors were exposed to appearance (n?=?51,588) or health-framed messages (n?=?52,639) directing them towards an AUDIT-C risk screening questionnaire. Users completing this questionnaire were given feedback on their risk level and extended frame-congruent information.

Outcomes: The primary outcome is completion of the AUDIT-C questionnaire. The secondary outcome is whether the participant accessed any of four further resources.

Results: The appearance-framed message led to a small but significant increase in the number of users completing the AUDIT-C compared to the health-framed message (n?=?3,537, 6.86% versus n?=?3,355, 6.37%, p?<?0.01). Conversely, following subsequent risk feedback, users exposed to extended health-framed information were more likely to access further resources (n?=?1,146, 2.17% versus n?=?942, 1.83%, p?<?0.01).

Conclusions: Physical appearance-framed messages increased the likelihood of engagement with an online alcohol screening and brief intervention tool, whereas health-framed messages increased the likelihood of accessing further resources. This highlights the potential for the use of multi-level approaches in alcohol reduction interventions.  相似文献

Objective: HIV stigma undermines health and well-being of people living with HIV (PLWH). Conceptual work on stigma mechanisms suggests that experiences of stigma or discrimination increase internalised stigma. However, not all PLWH may internalise the HIV discrimination they experience. We aimed to investigate the role of stress associated with events of HIV-related discrimination on internalised HIV stigma, as well as the downstream effects on depressive symptoms and alcohol use severity.

Design: 199 participants were recruited from an HIV clinic in the southeastern United States.

Main study measures: HIV-related discrimination was assessed using items adapted from measures of enacted HIV stigma and discrimination. Participants rated perceived stress associated with each discrimination item. Internalised HIV stigma was assessed using the internalised stigma subscale of the HIV Stigma Mechanisms Scale. Depressive symptoms were assessed with the Centre for Epidemiological Studies-Depression Index. Alcohol use severity was assessed with the Alcohol Use Disorders Identification Test.

Results: In serial mediation models, HIV-related discrimination was indirectly associated with both depressive symptoms and alcohol use severity through its associations with stress and internalised HIV stigma.

Conclusions: Understanding the mechanisms through which PLWH internalise HIV stigma and lead to poor health outcomes can yield clinical foci for intervention.  相似文献
