Connect to Protect (C2P), a 10‐year community mobilization effort, pursued the dual aims of creating communities competent to address youth's HIV‐related risks and removing structural barriers to youth health. We used Community Coalition Action Theory (CCAT) to examine the perceived contributions and accomplishments of 14 C2P coalitions. We interviewed 318 key informants, including youth and community leaders, to identify the features of coalitions’ context and operation that facilitated and undermined their ability to achieve structural change and build communities’ capability to manage their local adolescent HIV epidemic effectively. We coded the interviews using an a priori coding scheme informed by CCAT and scholarship on AIDS‐competent communities. We found community mobilization efforts like C2P can contribute to addressing the structural factors that promote HIV‐risk among youth and to community development. We describe how coalition leadership, collaborative synergy, capacity building, and local community context influence coalitions’ ability to successfully implement HIV‐related structural change, demonstrating empirical support for many of CCAT's propositions. We discuss implications for how community mobilization efforts might succeed in laying the foundation for an AIDS‐competent community.  相似文献

Exposure to negative math-gender stereotypes undermines the intentions of female college students to engage in careers in the math field, yet the mechanisms by which such stereotypes relate to girls’ career intentions remain unclear. We simultaneously tested multiple mediators in a sample of 186 female students from one high school in central China. Participants completed five questionnaires that measured mathematics-related gender stereotypes, competence beliefs, task value, sexual attraction beliefs and career intentions. The path analysis results indicated that math-gender stereotypes were negatively related to adolescent girls’ career intentions in math fields through negative relationships with students’ mathematics-related competence beliefs, task value and sexual attraction beliefs. These results are discussed in terms of their implications for theory and educational practice.  相似文献

为明确社交网站中的上行社会比较对青少年抑郁的作用机制,本研究构建了一个有调节的中介模型,重点考察了妒忌在二者关系中的中介作用、反刍思维的调节作用及其性别差异。以836名高中生为被试(M=16.34岁,SD=1.06),采用问卷法对社交网站中的上行社会比较、妒忌、反刍思维以及抑郁进行调查。结果显示:(1)在控制性别、年龄、年级、社交网站好友数量以及平均每天使用社交网站频率、时间后,社交网站上行社会比较对抑郁具有显著的正向预测作用;(2)妒忌能够在社交网站上行社会比较与抑郁的关系中起中介作用,且这种间接效应会受到反刍思维的调节;(3)有调节的中介模型存在性别差异:与男生相比,妒忌的中介效应在女生被试群体中更显著;在男生被试群体中,妒忌的中介作用会受到反刍思维的调节作用的影响,而在女生被试群体中,该调节效应不显著。  相似文献

One tradition in research for explaining aggression and antisocial behavior has focused on social information processing (SIP). Aggression and antisocial behavior have also been studied from the perspective of executive functions (EFs), the higher-order cognitive abilities that affect other cognitive processes, such as social cognitive processes. The main goal of the present study is to provide insight into the relation between EFs and SIP in adolescents with severe behavior problems. Because of the hierarchical relation between EFs and SIP, we examined EFs as predictors of SIP. We hypothesized that, first, focused attention predicts encoding and interpretation, second, inhibition predicts interpretation, response generation, evaluation, and selection, and third, working memory predicts response generation and selection. The participants consisted of 94 respondents living in residential facilities aged 12–20 years, all showing behavior problems in the clinical range according to care staff. EFs were assessed using subtests from the Amsterdam Neuropsychological Test battery. Focused attention was measured by the Flanker task, inhibition by the GoNoGo task, and working memory by the Visual Spatial Sequencing task. SIP was measured by video vignettes and a structured interview. The results indicate that positive evaluation of aggressive responses is predicted by impaired inhibition and selection of aggressive responses by a combination of impaired focused attention and inhibition. It is concluded that different components of EFs as higher-order cognitive abilities affect SIP.  相似文献

在一般攻击模型(GAM)和个体-环境交互作用模型的视角下,采用儿童心理虐待与忽视量表、青少年道德推脱问卷和攻击行为问卷对696名青少年进行调查,以探讨心理虐待与忽视对青少年攻击行为的影响以及道德推脱在其中的作用机制。结果发现:(1)心理虐待与忽视与青少年攻击行为和道德推脱均呈显著正相关,道德推脱与青少年攻击行为也呈显著正相关;(2)道德推脱在心理虐待与忽视和青少年攻击行为之间起着部分中介作用,道德推脱的中介作用不存在性别差异,但存在显著的年龄差异,在初中组中,道德推脱在心理虐待与忽视和青少年攻击行为间的中介作用为部分中介,而在高中组中为完全中介;(3)道德推脱在心理虐待与忽视和青少年攻击行为之间的调节作用不显著,道德推脱的调节作用不存在年龄差异,但存在显著的性别差异,在男生组中,道德推脱在心理虐待与忽视和青少年攻击行为间的调节作用不显著,而在女生组中显著。  相似文献

本研究采用社交网站中的自我表露量表、自尊量表、感知积极反馈量表和孤独感量表对武汉市八所普通中学1588名11~19岁的中学生进行调查,考察社交网站中的自我表露和孤独感的关系,以及感知积极反馈在二者关系间的中介作用和自尊对这一中介作用的调节。结果显示:(1)在控制了性别、年龄和社交网站使用时间后,社交网站中的自我表露显著负向预测青少年孤独感;(2)感知积极反馈在社交网站中的自我表露和孤独感之间起部分中介作用;(3)社交网站中的自我表露经由感知积极反馈影响孤独感的中介作用受到自尊的调节。具体而言,感知积极反馈的中介效应只出现在高自尊者中,在低自尊者中并不存在上述中介作用。  相似文献

为探讨同伴地位影响青少年冒险行为的作用机制及条件,采用青少年冒险行为问卷、同伴提名问卷、自我控制能力问卷、同伴群体特征问卷对山东省日照市1288名初高中学生进行调查。结果发现,(1)同伴地位负向预测青少年冒险行为,该预测作用是通过交往不良同伴的中介作用实现的;(2)交往不良同伴对青少年冒险行为的预测受到个体自我控制能力的调节。对于高自我控制能力青少年,其冒险行为与交往不良同伴无关,但低自我控制能力青少年会因交往不良同伴而参与更多冒险行为。结果提示培养良好的自我素质,塑造良好的同伴环境对于青少年的健康发展有重要作用。  相似文献

Few studies have examined the impact of violent victimization on friendship networks. This study used 2 waves of data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to examine the effects of violent victimization on number of peer- and self-reported friendships. Guided by stigma theory (Goffman, 1963), fixed-effect regression models controlling for depression, delinquency, substance use, and school engagement were completed to predict changes in number of friends following victimization. Consistent with the theory, results indicate that experiencing violent victimization (e.g., jumped, stabbed, shot at) was associated with a decrease in number of friends. These effects were magnified for females and for individuals with a greater number of depressive symptoms. These results were consistent even when models were run separately for each individual type of victimization. Treatment and prevention implications are discussed.  相似文献
