This study contributes to the growing literature on individual-level outcomes of corporate social responsibility (CSR). Employing a sample of 339 subordinate–supervisor dyads, we explored the differential impact of CSR attributions on employees’ creative performance in the telecom industry. We also introduced and tested the role of psychological safety as a mediator underlying this relationship. The results indicate that although intrinsic CSR attributions are not directly related to creative performance, extrinsic CSR attributions have a significant negative effect on creative performance. We also found that psychological safety mediates the positive relationship between intrinsic CSR and creative performance and the negative relationship between extrinsic CSR and creative performance. Directions for future research and implications for practice are discussed.  相似文献

Background and Objectives: Deployment-related risk factors for suicidal ideation among Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans have received a great deal of attention. Studies show that mental health symptoms mediate the association between most deployment stressors and suicidal ideation; however, family-related factors during deployment are largely unexplored. We examined posttraumatic stress disorder (PTSD) and depression symptoms as mediators of the associations between deployment family support and stress and post-deployment suicidal ideation in combat-exposed OEF/OIF veterans. Design: National cross-sectional mail survey. Methods: 1046 veterans responded to the survey. The sample for this study was 978 veterans who experienced combat. Regression-based path analyses were conducted. Results: Family support and stress had direct associations with suicidal ideation. When PTSD and depression symptoms were examined as mediators of these associations, results revealed significant indirect paths through these symptoms. Conclusions: This study contributes to the literature on suicidal ideation risk factors among OEF/OIF veterans. Deployment family support and family stress are associated with suicidal ideation; however these associations occur primarily through mental health symptomatology, consistent with findings observed for other deployment factors. This research supports ongoing efforts to treat mental health symptomatology as a means of suicide prevention.  相似文献

Summary

This article examines the role of psychosocial and behavioral dimensions of terrorism that influence community preparedness and homeland defense efforts. Public health interventions will fail if people do not follow the recommendations. A broader public health model is applied to help identify the interactions between risk and safety appraisals, social factors, and behavioral response to uncertain and stressful situations. Community preparedness would benefit by linking disparate programmatic and advocacy initiatives that already exist. It stands to reason that improving the cohesiveness of existing systems of social organization would strengthen community resilience and serve as effective countermeasures for terrorism.  相似文献

This research reports on an investigation of if and how help-seeking women perceived that they had coped in intimate partner violence situations. Within a cross-sectional design, a representative sample of 157 help-seeking women in Norway was interviewed. Multivariate logistic regression analysis was conducted. Results indicated that exposure to psychological, physical, and sexual intimate partner violence, respectively, did elicit different coping strategies in one and the same woman. There were also significant differences between women who perceived they had effective coping strategies and those who did not. This research suggests that a multivariate design within an interactional perspective could inform and enhance our understanding of coping strategies in intimate partner violence situations as complex, heterogeneous, and dynamic phenomena.  相似文献

I examined the reconstructive processes of remembering past events when new information is made available. Analyses with a variety of materials and conditions failed to reveal effects for distortion in recognition memory for retrospective label manipulations. Effects of prior knowledge were consistently strong and highly resistant to subsequent biasing information. The results suggest that people are less susceptible to thematic-based, stereotypic information and possess a memory network more flexible than traditional research implies.  相似文献

The interrelationship of digit span and word span was studied in a group of 112 females, 17-81 years of age. When the subjects were assigned to groups of 38 young ([Xbar] = 25.6 years), 39 middle-aged ([Xbar] = 53.2 years), and 35 old ([Xbar] = 73.3 years), the correlation between the two types of span was larger in the old than in the young, reflecting a predicted greater degree of homogeneity of functioning. When spans were scored without consideration for exact order of recall, this finding no longer held, as was the case with a capacity decrement in digit span with the aged, thus reflecting the importance of the organizational factor in senescent memory ability.  相似文献

Past studies suggest that positive affect produces a wide range of desirable outcomes because it helps people build lasting resources. It may be assumed that these resources build on positive affect over time, which in turn may explain the beneficial effect of positive affect in stressful encounters. However, this assumption has not been directly tested by empirical studies. This question is important in that it helps clarify the underlying mechanism through which individuals with more positive affect might respond adaptively to adverse situations. Using a stressful task that included 20 rounds of risky investment choices, the current study examined whether psychological resilience, an important personal resource fuelled by positive affect, could account for the beneficial effects of positive affect. Specifically, we examined the relationship between individuals’ baseline levels of positive affect, their levels of psychological resilience, their choices in a risky investment decision task, and their levels of positive affect on the final investment task. The results demonstrate that psychological resilience could indeed help explain happier people's enhanced outcomes: They chose higher return although more risky investment options and experienced more positive affect at the end of the task. The current study supports the notion that individuals who experience frequent positive affect thrive through various challenges not simply because they feel good, but because they have resources that they can utilize to deal with these challenges. Findings from the present study support further investigation of the important relationship between specific positive affect, psychological resilience, and performance in risky investment tasks.  相似文献

耳鸣的心理机制   总被引:1,自引:0,他引:1  
现有研究表明, 耳鸣给患者带来的心理问题比机体自身的病理损伤更为严重, 其中最突出的是患者的注意与情绪问题。近年来, 研究者利用多种方法从多角度证实了耳鸣患者存在不同程度的注意障碍; 同时, 影像学研究也发现部分情绪脑区的活性增强与耳鸣患者的情绪障碍显著相关。这些研究成果不仅为耳鸣的客观评估提供了可行性依据, 也为心理治疗的进一步发展奠定了基础。随着耳鸣患者对生活质量要求的提高, 未来耳鸣研究应着重帮助患者缓解负性情绪, 纠正不良行为, 帮助其重新过上正常的生活。  相似文献
