Thin-Ideal Internalization: Mounting Evidence for a New Risk Factor for Body-Image Disturbance and Eating Pathology

Body-image disturbance and eating disorders are a significant physical and mental health problem in Western countries. We describe emerging work on one newly identified variable that appears to be a potent risk factor for the development of these problems internalization of societal standards of attractiveness. Work conducted independently in our labs over the past decade has included scale development, correlational studies, prospective risk-factor studies, randomized experiments, and randomized prevention trials. Findings collectively suggest that internalization is a causal risk factor for body-image and eating disturbances, and that it appears to operate in conjunction with other established risk factors for these outcomes, including dieting and negative affect. Future research is needed to examine the specific familial, peer, and media influences that promote internalization and to replicate and extend our prospective and experimental studies.     

Evaluating the method of levels

An investigation of the method of levels (MOL) was undertaken. Based on the principles of perceptual control theory (PCT), MOL is a way of helping people to reduce psychological distress. MOL assumes that psychological distress results when people are unable to control experiences that are important to them. The approach was implemented over six months in a large urban GP practice. Patients attended for between one and six sessions. Patients who attended for more than one session demonstrated significant reductions in scores of symptomatology on a standardized questionnaire. Effect sizes of these differences were relatively large. There appeared to be no relationship between the number of sessions a patient attended and the amount of reduction in symptomatology that was recorded. Similarly, there was no relationship between the number of sessions a patient attended and their recorded level of symptomatology at their first appointment. Although the study has important limitations we suggest that these findings might offer new directions for future research and might provide a way of unifying the specific and common factors as well as understanding the Dodo Bird effect.     

Dynamics of Peer Victimization in Early Adolescence

ABSTRACT

This study addressed the stability of victimization across four consecutive years from Grades 4 to 7, and the concurrent correlates, short-term consequences, and predictors of victimization in early adolescence. Participants were 600 students (49% girls) enrolled in 10 elementary schools in Grades 4-5 and 2 middle schools in Grades 6-7 in an ethnically diverse school system. Data collection included peer nominations, self-reports, and teacher reports in each year. Victimization was highly stable across all years, including the transition from elementary to middle school. Both concurrent and short-term consequences showed that victimized 6th graders, especially girls, experienced significantly greater maladaptive outcomes than their nonvictim counterparts. For both genders, risk factors for adolescent victimization included externalizing and internalizing behaviors, while protective factors included academic and peer sociability elements. Implications for prevention and intervention are discussed.     

Still Doing Fine? The Interplay of Negative Life Events and Self‐Esteem During Young Adulthood

This longitudinal study investigated the bidirectional relationship between negative life events and self‐esteem during the transition from adolescence to young adulthood (N = 2272). Drawing on theories of human development over the lifespan and just‐world theory, we analyzed age‐graded changes in self‐esteem and their interplay with negative life events at three measurement points over a 12‐year period. We addressed both the short‐term and the longer term effects of single as well as multiple negative life events on changes in self‐esteem (socialization effects). We further investigated whether the pre‐event level of self‐esteem affected the likelihood of negative life events occurring (selection effects) and, finally, whether it had protective effects in terms of helping people adjust to negative events. Latent change models yielded four main findings: (i) self‐esteem increased during young adulthood; (ii) socialization effects were observed over shorter and longer timespans, but (iii) selection effects were only found for multiple negative life events, with low self‐esteem predicting a high number of negative life events; (iv) high pre‐event self‐esteem acted as a protective factor, attenuating declines in self‐esteem after experience of multiple negative life events.

应当重视肿瘤微环境中外因的研究

长期以来,肿瘤学的几乎所有研究一直在关注肿瘤细胞本身,从哲学角度看这无疑是正确的。肿瘤细胞是肿瘤事件发生发展的内因。近年研究表明,肿瘤的外因,即肿瘤微环境中的非肿瘤细胞及其产物,对肿瘤的发生发展起着十分重要的作用。肿瘤微环境的外因,通过作用于内因选择了更具抵抗性的肿瘤细胞,促进了肿瘤的进展与转移。因此,重视肿瘤微环境的外因研究,对肿瘤治疗学将会开辟以外因为靶点干预的新思路。     

语篇理解中语义整合的神经机制及其影响因素

语义整合是把当前阅读中新出现的词语与之前的语境进行语义联结以形成连贯表征的过程。在语篇理解中, 很多理论都确定了整合这一过程的重要性, 语义整合是达成语篇连贯的一个关键步骤, 探究其神经机制及影响因素对理解语篇有重要意义。已有的ERP研究表明语篇理解中的语义整合是即时发生的; 已有的fMRI研究和神经震荡的分析提供了参与这一过程的具体脑区和神经网络的证据。其影响因素主要包括语篇内因素、非言语因素和个体差异。     

医务人员职业倦怠压力源因素分析——以锦州某医院的调查为例

医务人员职业倦怠的影响因素有多种,如宏观层面的执业环境、中观层面的医院管理,以及微观层面的个体自身。以锦州市某医院医务人员为调查对象,采用问卷调查法和访谈调查法相结合的方式,识别影响职业倦怠的主要压力源因素。调查发现,中观层面的因素对医务人员职业倦怠影响较大,进而对此提出有效的预防及干预对策,如构建医务人员健康档案,建立医患冲突防范系统,加强对医务人员沟通能力的培训,实行多元化考核方式,实施绩效薪酬积分制度等。     

谣言传播的影响因素及动机机制研究述评

谣言是指一种据称真实但未经证实的普遍流传的说法。谣言会通过社会成员之间的信息传递而影响公众的态度和行为。谣言在传播过程中,既受到个体水平上的认知和情绪变量的影响,也受到群体变量及情境变量的影响。个体传播谣言的心理动机包括寻求事实、关系提升和自我提升。谣言在突发公共事件（自然灾害、事故灾难、公共卫生事件、社会安全事件等）中具有很大的破坏性,在群体性事件中谣言的传播、扩散会使矛盾更加激化,冲突进一步升级。未来的研究需要进一步探查影响谣言传播的群体因素,从群体动力学的角度探究谣言传播的心理机制,并考虑谣言在突发社会事件中传播的特征。

教师成就目标的测量及其与学校目标结构的关系

首先,依据Elliot关于成就目标的能力界定标准和能力效价的理论构想,提出教师成就目标的理论结构。浙江省内外十多所中小学523份有效调查数据的探索性和验证性因素分析的结果表明,教师成就目标由6个因素构成,即:绝对-回避目标、个人-回避目标、参照-回避目标、个人-接近目标、参照-接近目标、绝对-接近目标。然后,利用浙江省内外另外十多所中小学625份调查问卷的结果,采用结构方程模型技术对教师成就目标和学校目标结构之间的关系进行了分析。结果表明,掌握目标结构对绝对-接近目标、个人-接近目标具有显著正效应,对绝对-回避目标具有显著负效应;成绩目标结构对绝对-接近目标、参照-接近目标、个人-回避目标和参照-回避目标具有显著正效应。
