从"生物—心理—社会"的视角全面地探讨灾难情境下的人们的社会心态变化规律及其特点有一定的学术价值。生物学视角的研究成果表明,灾难后的心理行为变化源于人类前额叶的高级认知控制功能受到应激影响的条件下转变为由杏仁核所主导的快速情绪反应模式。心理学视角的研究分析认为,灾难后的心理行为变化可看做进化心理学和精神分析理论双重意义上的心理原始化过程。社会文化视角的分析认为,灾难后的心理行为变化可看做一种社会文化心态模式从"平时状态"向"灾难应急模式"的转换。这三个视角的研究分析既有内在本质的联系,也遵循各自不同的逻辑,只有将这三个视角结合起来考虑,我们才能获得对于灾难后社会心态变化的全面认识。  相似文献

This study examined the role of three spiritual responses to divorce for psychological adjustment: appraising the event as a sacred loss/desecration, engaging in adaptive spiritual coping, and experiencing spiritual struggles. A sample of 100 adults (55% female) was recruited through public divorce records. Most appraised their divorce as a sacred loss/desecration (74%), experienced spiritual struggles (78%), and engaged in adaptive spiritual coping (88%). Appraisals of sacred loss/desecration and spiritual struggles were tied to higher levels of depression. Adaptive spiritual coping was tied to greater posttraumatic growth. Spiritual coping and struggles each contributed uniquely to adjustment beyond parallel forms of nonspiritual coping and struggles and mediated links between viewing the divorce as a sacred loss/desecration and depression.  相似文献

As the numbers of caregivers continue to increase, more attention is being focused on the unique stresses these individuals experience. Caring for a loved one tests the limits of even the most resilient, regardless of professional status or experience. Laughter is a universal elixir which allows people to cope more sanely with stress and caregiving responsibilities. Research on the emotional and physical benefits of laughter supports the use of humor by professionals and family members who occupy caregiving roles. This article addresses this research and examines common caregiver emotions while providing concrete guidelines for developing humor. Case examples demonstrate how laughter and wit are utilized by those caring for a loved one.  相似文献

Previous research has suggested that high levels of burnout lead to impaired functioning on the job. However, as this research has usually relied on self-reported performance, it is imperative to examine whether this association is also confirmed when using “objective” performance data (e.g., supervisor reports). This study reviewed previous research on the associations between burnout (exhaustion, depersonalization, and personal accomplishment) and various types of objective performance. A systematic literature search identified 16 studies dealing with the burnout-performance relationship. These studies showed the wide variety of approaches that are used to study burnout and objective performance. Using data from these 16 studies, a meta-analysis was conducted to obtain mean correlations. The meta-analytical correlations between exhaustion and in-role behaviour (based on five studies), organizational citizenship behaviour (OCB; five studies), and customer satisfaction (two studies) were -.22, -.19, and -.55, respectively, underlining the practical relevance of burnout research for organizational performance. The evidence for the relationships between depersonalization, personal accomplishment, and performance was inconclusive. Future research should focus on valid indicators of job performance, should more often employ longitudinal designs and large samples, and should consider the theoretical basis for the study expectations more extensively.  相似文献

Abstract

This paper presents some recent data on why organizations invest in exercise and physical fitness programmes for their stiff. These data suggest that, owing to a lack of evaluation studies, organizations act mainly on the basis of assumption and belief. However, from a subsequent review of the available literature on the personal and organizational effects of such programmes, it appears that these assumptions and beliefs are not altogether unfounded. The paper concludes by discussing the ways in which exercise and employee fitness programmes might help die individual and their organization in terms of the management of health at work.  相似文献

Abstract

A context-dependence paradigm was developed for research into effects of the menstrual cycle in women. This involved the investigation of situational effects on self-reported distress in both men and women. For 35 consecutive days, 25 women and 36 men working in two occupations that varied in degree of situational stress completed Body Awareness Questionnaires (modified menstrual distress questionnaires) and daily subjective stress ratings. After controlling for contraceptive use, age range, and percentage of body fat, the following variables were selected for a multiple regression analysis as predictors of distress: (a) job stress, (b) feminine values, (c) life stress, (d) subjective stress, (e) type of job, (f) sex, (g) job experience, and (h) history of menstrual distress. Women working in the high-stress job (military police) reported significantly more distress than all the other groups. Life stress was identified as the dominant predictor of distress. In a separate analysis of daily distress scores and menstrual cycle phases for all the women, there was no interaction between the type of job and the menstrual cycle phase on reports of distress. A similar analysis of the effects on sex and shift revealed shift effects in distress for men but not women. Sources of variability for both sexes (shift-work rotation and cycle phase) are discussed.  相似文献
