Catching aggression from one's peers: A longitudinal and multilevel analysis

Exposure to peer aggression is a major risk factor for the development of aggressive behavior in childhood and adolescence. Furthermore, peer aggression has the propensity to spread and affect individuals who were not exposed to the original source of aggression. The aim of this paper is to demonstrate that peer aggression is in many regards similar to a contagious disease. By presenting a program of research based on longitudinal and multilevel studies, we provide evidence for the contagious quality of aggressive behavior, show that individuals vary in their susceptibility to peer aggression, and describe group‐level characteristics that moderate the influence of peer aggression. We discuss mechanisms that may explain how individuals catch aggressive behavior from their peers and how the effects on the development of individuals' aggressive behavior unfold over time. Further, we examine processes that may increase the risk of being exposed to peers' aggressive behavior. We conclude with discussing implications for future studies on the contagious nature of peer aggression.     

Social identity uncertainty: Conceptualization,measurement, and construct validity

The following paper establishes a measurement of social identity uncertainty. Based on uncertainty-identity theory, we propose social identity uncertainty is a unique type of self-uncertainty related to group identification. We further believe social identity uncertainty is comprised of two components: identity-uncertainty (i.e., uncertainty about one’s group identity) and membership-uncertainty (i.e., uncertainty about being a group member). Study 1 (N = 314) and Study 2 (N = 299) explored and confirmed that two subcomponents exist within social identity uncertainty. Study 3 (N = 295) developed convergent validity using various social identity-related constructs, and discriminant validity using dispositional constructs. Overall, we found (a) identity-uncertainty and membership-uncertainty are distinct constructs, and (b) our measurements have both convergent and discriminant validity.     

Burnout among Finnish and Chinese university students

In this study the levels of experienced burnout of Finnish and Chinese university students are compared using School Burnout Inventory (SBI). This study is motivated by earlier studies, which suggest that the level of student burnout is different in the culturally distinct Finnish and Chinese university systems, but which are based on different research instruments for the two groups. The sample studied consisted of 3,035 Finnish students and 2,309 Chinese students. Because of the cross‐cultural nature of this study the level of structural equivalence of SBI between the cultural groups was examined and the effect of different response styles on the results was taken into account. Both standard and robust statistical methods were used for the analyses. The results showed that SBI with two extracted components is suitable for cross‐cultural analysis between Finnish and Chinese university students. Virtually no difference was found in experienced overall burnout between the Finnish and Chinese students, which means that both university systems contain factors causing similar levels of student burnout. This study also verified that controlling for the response styles is important in cross‐cultural studies as it was found to have a distinct effect on the results obtained from mean‐level comparisons.     

Predictors of Stress Generation in Adolescents in Mainland China

The current longitudinal study examined whether the personality vulnerabilities of self-criticism and dependency prospectively predicted stress generation in Chinese adolescents. Participants included 1,116 adolescents (588 girls and 528 boys), aged 15 to 18 years from rural, urban and ultra-urban mainland China. Participants completed self-report measures of personality, depressive and anxious symptoms and participated in a clinical interview assessing lifetime history of depression. The occurrence of negative life events was measured using a contextual-threat interview every 6-months for a total period of 18-months. Logistic regression analyses showed that after controlling for past depressive episodes and current depressive and anxious symptoms, self-criticism was prospectively associated with the occurrence of interpersonal stress generation, but not noninterpersonal stress generation. Dependency also predicted interpersonal stress generation, although only in girls and not boys. In line with previous Western findings, girls reported more interpersonal stress generation. Analyses across 3 levels of urbanization revealed several significant differences including higher reported interpersonal stress generation in urban girls than urban boys and overall higher levels of negative life events in ultra-urban youth. In sum, findings from the current study suggest that the stress generation process may be generalizable to Chinese youth.     

在线抑制控制训练对失败的限制性饮食者不健康食物选择的改善

失败的限制性饮食者是进食障碍的高危人群,他们面对食物时的抑制控制能力通常很弱,从而更易发展为肥胖,所以改善失败的限制性饮食者对不健康食物的进食选择十分重要。本文采用在线停止信号任务,通过提高失败的限制性饮食者对不健康食物图片的抑制控制能力,从而减少他们在日常生活中对不健康食物的选择。首先对66名失败的限制性饮食者实施前测,然后随机分为对不健康食物图片进行抑制反应的干预组(n=33)和对非食物图片进行抑制反应的控制组(n=31),两组被试接受每天一次(每次10 min左右)共计7次的训练。完成训练后,所有被试均接受后测。结果发现,干预训练后,与控制组相比,干预组被试对不健康食物的选择频率以及对不健康食物自我报告的吸引力和喜爱程度均显著降低。     

父母对幼儿消极情绪的反应方式与幼儿情绪调节能力的关系

以西安市280名幼儿及其家长为被试,采用问卷法考察母亲、父亲对幼儿消极情绪的反应方式对幼儿情绪调节能力的单独效应和联合效应。结果发现：（1）母亲对幼儿消极情绪的支持反应正向预测幼儿的情绪调节能力,非支持反应负向预测幼儿的情绪调节能力;（2）父亲对幼儿消极情绪的支持反应和非支持反应显著预测女孩的情绪不稳;（3）在女孩的情绪调节能力上,母亲和父亲非支持反应的交互作用显著,部分支持了分歧模型。     

家庭功能与流动青少年认同整合的关系:希望与父母文化持守的作用

本研究采取整群抽样的方法对来自广东省三所民办中学的1345名流动青少年进行问卷调查,探查流动青少年的家庭功能对其认同整合的影响,以及希望和父母文化持守在其中所起的作用。结果表明：（1）流动青少年的家庭功能正向预测了认同整合。（2）希望在流动青少年的家庭功能与其认同整合两者间起部分中介作用,家庭功能既对认同整合产生直接影响,也通过希望对认同整合产生间接影响;（3）流动青少年的父母文化持守调节了家庭功能与认同整合的关系。     

途径偏向矫正训练对药物成瘾相关线索反应的调节

研究目的:通过针对"相关线索-习惯性用药行为"联结的消退训练,降低渴求感,建立新联结,达到减弱或消退成瘾记忆的目的。探索以"动作消退动作"的方法对成瘾动作记忆进行消退的效果和可行性。方法:采用途径偏向矫正方法对28名男性药物成瘾者开展为期4周的训练。训练前后,分别测试渴求感、生理指标、途径偏向效应和Addiction-stroop task的干扰效应量,比较训练前后的指标变化,了解训练的效果。结果:训练组和对照组在训练前后的途径偏向效应没有显著的组间和交互效应,但训练组在训练前后途径偏向效应发生变化,趋向显著性,t=1.26,p=0.071。渴求感在训练组显著降低:t=1.38,p=0.05。Stroop的反应时间呈训练时间主效应:t=4.18,p=0.04。结论:途径偏向矫正消退训练可以改善成瘾者的途径偏向效应和渴求感状况,预示着通过身体动作建立"相关线索-拒绝用药行为"联结替代原有的"相关线索-自动化用药行为"联结,降低渴求感,减弱或消退成瘾记忆是有可能的。未来的研究需要采用更为精确的影像手段进行测试,验证基于动作认知的成瘾记忆消退训练的有效性。
