以新生代农民工为研究对象,以其对群际通透性的感知为测量指标,检验积极群际接触的有效性,探察群体受害者身份感知和群体认同对积极群际接触有效性的影响,以及群体认同在群体受害者身份感知与积极群际接触关系中的作用。结果表明:(1)积极群际接触可以有效促进新生代农民工对群际通透性的感知;(2)新生代农民工群体受害者身份感知对积极群际接触有效性有显著的中介作用;(3)新生代农民工的城市人认同水平对积极群际接触有效性具有显著的调节作用;(4)新生代农民工群体受害者身份感知对积极群际接触有效性的中介作用不受其群体认同水平的影响。研究结论对积极群际接触的有效性和感知的群体受害者身份与群体认同的关系进行了深入地讨论。  相似文献

探究仁慈领导与员工创新行为的关系,以及在该关系中内部人身份感知的中介作用和领导-部属交换关系差异化的调节作用。以68名主管和215名员工为对象,通过对两阶段主管-员工配对调查所获取的数据进行分析,结果表明:(1)仁慈领导可以借助内部人身份感知的中介作用,对员工创新行为产生积极的影响;(2)领导-部属交换关系差异化能调节仁慈领导和内部人身份感知的关系,即当关系差异化水平越高,仁慈领导与内部人身份感知之间的正向关系越强;(3)领导-部属交换关系差异化能调节内部人身份感知在仁慈领导与员工创新行为关系间的中介作用,表现为被调节的中介作用模式,即领导-部属交换关系差异化水平越高,仁慈领导与员工创新行为之间通过内部人身份感知的间接关系越强。  相似文献

This study examined adolescents with low vision (LV) compared to students without disabilities regarding their cyberbullying experiences, as related to perceived social support. Sample consisted of 407 students (61 with LV) who completed self-reported questionnaires. Findings revealed that students with LV are using the computer and the Internet as much as the typical students, but students with LV had less frequent Internet interactions with friends. Students with LV reported being more involved in cyberbullying as cybervictims, cyberperpetrators, cyberwitnesses, knowing someone and telling their online experience to another, and having lower social support compared to students without disabilities. Students with LV are more willing to report and to share their online experiences with another person. The findings add to our knowledge about students’ experiences of cyberbullying and suggest implementing effective coping strategies programs to raise the awareness of cyberbullying risky behavior.  相似文献

从社会认知理论的视角来探讨网络社会支持和网络人际信任的关系,并在此基础上提出了一个有调节的中介模型,考察网络社交效能的中介作用以及自尊的调节作用.采用整群抽样法对432名大学生进行问卷调查,结果表明:(1)网龄对网络人际信任有显著的负向预测作用;网络社会支持对网络人际信任具有显著正向预测作用;(2)网络社交效能在网络社会支持与网络人际信任的关系中起部分中介作用;(3)网络社会支持通过网络社交效能对网络人际信任的间接效应受到自尊的调节.对高自尊个体而言,网络社交效能起部分中介作用;对低自尊个体而言,网络社交效能的中介效应不显著,网络社会支持对网络人际信任只有直接作用.  相似文献

The study investigated the mediating role of perceived control in the association between religiosity and quality of life among young adults in south-west Nigeria. Data were collected from a sample of 1 050 young adults (mean age = 29.8, SD = 4.61; female = 38.7%). Regression analysis was utilised to predict quality of life from religiosity, partialling out perceived control. Findings suggest internal religiosity to predict an environmental domain of quality of life through perceived control. Perceived constraints appear to explain the association between internal religiosity and the environmental domain of quality of life.  相似文献

Summary

Trauma is proposed as a key to understanding the development and persistence of conduct disorder, in conjunction with other contributing factors. Trauma history is ubiquitous in the conduct disordered population, and trauma effects can help to account for many features of conduct disorder, including lack of empathy, impulsivity, anger, acting-out, and resistance to treatment. The current standard of care fails to fully address trauma, which may partially explain the low success rate of extant treatment approaches. A trauma-informed perspective is introduced to current models of conduct disorder. Research, prevention, and treatment implications are discussed.  相似文献

Drawing on social comparison and equity theories, we investigated the role that perceived similarity of a comparison target plays in how resentful people feel about their relative financial status. In Study 1, participants tended to choose a comparison target who was better off, and they selected a target they perceived to be more similar than dissimilar along dimensions that surrounded their financial outcomes. In Study 1, perceived relative disadvantage was positively associated with resentment regardless of the perceived similarity of the comparison target. The results of Studies 2 to 5b clarified these findings by showing that being both similar and dissimilar to a target can cause resentment depending on the context. Using hypothetical and real social comparisons, we found that people are more dissatisfied with their financial outcomes when their comparative targets have the same background qualifications (i.e., are similar) but are financially better off (Studies 2, 3b, 4, and 5b). However, we also found that when the comparative financial contexts were similar (i.e., equal affluence), participants were more dissatisfied when their target for comparison had lower qualifications (i.e., was dissimilar; Studies 2, 3a, 4, and 5a). In all cases, perceptions of unfairness mediated the effects of social comparison on financial dissatisfaction. Taken together, these studies address some of the ambiguities around what it means to be similar to a target in the context of social comparisons of affluence, and they underscore the importance of perceived unfairness in the link between social comparison and resentment with one's financial status.  相似文献

为探讨自闭症和智力障碍儿童行为问题与其父母焦虑的关系及其内在作用机制,研究采用问卷法对1023名自闭症和智力障碍儿童父母进行调查。结果表明:(1)自闭症和智力障碍儿童行为问题对父母焦虑具有正向预测作用;(2)育儿压力在儿童行为问题和父母焦虑间起中介作用;(3)儿童行为问题与育儿压力的关系受到领悟社会支持水平的调节,调节作用只在智力障碍儿童父母群体中显著。研究结果有助于揭示自闭症和智力障碍儿童行为问题对父母焦虑的影响及作用机制,对改善自闭症和智力障碍儿童父母育儿压力与焦虑具有一定指导意义。  相似文献

People generally intend to act more on beliefs and attitudes about which they have greater certainty. However, we introduce a boundary condition to the positive association between certainty and behavioral intentions—behavioral extremity. Uncertainty about a threatening issue like COVID-19 can be disconcerting, and we propose that uncertain people cope in part through increased openness to extreme actions like accepting risky medical treatments and aggression toward those defying mitigation policies. Testing this, we compiled and analyzed all the data on certainty about COVID-19 mitigation policies and willingness to engage in mitigation-related behaviors that our lab collected during the pandemic (6 samples, 20 behaviors, Ns up to 1496). External ratings of the behaviors' extremity moderated certainty-willingness associations: whereas greater certainty was associated with increased willingness to engage in moderate behaviors (the typical result), lower certainty was associated with increased willingness to engage in extreme behaviors, especially among those worried about becoming ill.  相似文献
