青少年应激下皮质醇应答与风险决策相关性的性别差异

本研究旨在探讨中国青少年应激下皮质醇应答和风险决策相关性的性别差异。本研究以健康初中生为被试者, 采用特里尔社会应激测试(Trier Social Stress Test, TSST)诱发机体应激反应, 测试唾液皮质醇在应激前后不同时间段的水平, 并要求被试者在应激状态下完成气球模拟风险决策任务(Balloon Analogue Risk Task, BART)。结果发现, 男性在TSST诱导下皮质醇反应度显著高于女性, 男性中高皮质醇应答者BART表现为更高程度的冒险行为和更低的总奖励金额, 而女性中高皮质醇应答者BART表现为更高的总奖励金额。研究结果提示,中国青少年应激条件下皮质醇应答与风险决策之间的联系存在性别差异, 尤其在男性, 高皮质醇应答者更具有冒险行为。

摘 要 对831名中学生施测青少年自评量表、父母知晓量表、专业心理求助态度问卷,考察青少年心理行为问题、父亲知晓、母亲知晓与专业心理求助态度的关系。结果发现：（1）青少年的专业心理求助态度与心理行为问题、父母知晓呈显著相关。（2）父亲知晓在青少年心理行为问题与专业心理求助态度的关系中起部分中介作用,母亲知晓的中介作用不显著。研究结果对青少年专业心理求助的干预有着重要意义。     

领悟社会支持、应对效能和压力性生活事件对青少年学业成就的影响机制

为揭示领悟社会支持与青少年学业成就的关系,以及应对效能的中介效应和压力性生活事件的调节效应,采用领悟社会支持问卷、应对效能问卷、压力性生活事件量表和学业成就问卷对1687名青少年进行研究。结果显示：（1）领悟社会支持能够促进青少年的学业成就;（2）应对效能对领悟社会支持与学业成就的关系具有中介效应;（3）压力性生活事件能够调节应对效能的中介作用。因此,领悟社会支持对学业成就的影响是有调节的中介效应。     

青少年早期自尊与抑郁的交叉滞后分析：检验易感模型和创伤模型

本研究以初一年级598名青少年为研究对象,采用三年追踪设计,运用交叉滞后回归分析,控制变量的先前水平,旨在揭示青少年早期自尊与抑郁的相互影响,检验易感模型和创伤模型。结果发现,对于青少年样本总体来说,第一、二学年抑郁各自能显著负向预测第二、三学年自尊,支持创伤模型;同时第二学年自尊又能显著负向预测第三学年抑郁,支持易感模型。对于女生而言,其自尊与抑郁之间的关系与样本总体相同,既支持易感模型,又支持创伤模型;对于男生而言,仅发现其第二学年抑郁能显著负向预测第三学年自尊,支持创伤模型。这些结果表明青少年早期的自尊与抑郁存在双向的相互影响,易感模型和创伤模型同时起作用,而且这种影响存在显著的性别差异。     

中国青少年情绪调节的发展特点

处于"暴风骤雨期"的青少年在情绪体验及情绪调节上发展迅速。文化价值以及社会规范是个体情绪调节及策略使用发展的重要影响因素。以往关于青少年情绪调节发展的结论大多源于西方文化背景,以西方青少年作为研究对象。然而,中国文化中关于情绪调节的价值和要求均与典型西方文化存在差异。近年来,研究者对中国青少年情绪调节的发展特点进行了系统的探索,发现中国青少年情绪调节的发展以减弱调节策略的运用为主导,并形成了非享乐主义的调节模式。     

青少年主观幸福感与网络成瘾:自尊及自我控制的中介作用

以1551名初高中生为被试,采用问卷调查法探讨主观幸福感与网络成瘾的关系,以及自尊及自我控制在其中的中介效应。结果表明:(1)主观幸福感与自尊、自我控制能力之间显著正相关,且均与网络成瘾显著负相关;(2)青少年的主观幸福感水平显著负向影响其网络成瘾,而且还通过自尊和自我控制间接影响青少年的网络成瘾,并且间接效应更加明显;(3)在主观幸福感作用于网络成瘾的关系中,自尊及自我控制单独作用时的中介效应一般,但是当两者联合作用时中介效应大幅增加。     

“民族认同，国家认同”与青少年自尊的关系

自尊被普遍认为是青少年的发展中的一个重要因素,已有研究发现它与心理幸福感呈显著的正相关,并与沮丧和绝望呈显著的负相关。就是由于自尊的心理上的重要性,所以有大量的研究来探讨它的影响因素。大多数对自尊的研究主要关注的是个体的能力和人际问的经历来作为自尊主要成分。尽管自尊的个人资源明显是很重要的,但是这样的关注忽略了自尊的群体成员方面的影响。本文就是探讨群体认同,尤其是考察民族认同和更广层面的国家认同.对少数民族青少年自尊的预测。     

Linking vitamin D status,executive functioning and self‐perceived mental health in adolescents through multivariate analysis: A randomized double‐blind placebo control trial

The aim of the present randomized double‐blind placebo control trial was to investigate if vitamin D supplementation had an effect on vitamin D status, executive functioning and self‐perceived mental health in a group of Norwegian adolescents during winter time. Fifty adolescents were randomly assigned into an intervention group (vitamin D pearls) or a control group (placebo pearls). Before (pre‐test in December/January) and after (post‐test in April/May) the intervention period the participants were exposed to a test procedure, consisting of blood draw, completion of cognitive tests (Tower of Hanoi and Tower of London), and the Youth Self‐report version of the Child Behavior Checklist. Multivariate data analysis showed that participants with low vitamin D status scored worse on the Tower of London tests and the more difficult sub‐tasks on the Tower of Hanoi tests. They also had a tendency to report higher frequency of externalizing behavior problems and attention deficit. At pre‐test, the overall mean vitamin D status measured as 25‐hydroxy vitamin D was 42 nmol/L, defining deficiency (Intervention group = 44 nmol/L, Control group = 39 nmol/L). However, vitamin D supplementation caused a significant increase in vitamin D status resulting in a sufficient level in the Intervention group at post‐test (mean 62 nmol/L). The results also revealed that the intervention group improved their performance on the most demanding sub‐tasks on the ToH. Overall, the study indicates that vitamin D status in adolescents may be important for both executive functioning and mental health.     

Structural and Community Change Outcomes of the Connect‐to‐Protect Coalitions: Trials and Triumphs Securing Adolescent Access to HIV Prevention,Testing, and Medical Care

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.
