Fear of victimization may have consequences for subjective well-being. I develop and test a model linking fear of victimization to subjective health. I hypothesize that two processes link fear to subjective health-psychological and behavioral. Specifically, I hypothesize that fear of victimization increases psychological distress, and fear decreases outdoor physical activity, especially walking. High levels of psychological distress and low levels of walking, in turn, are associated with poor self-reported health. I find empirical support for the hypothesized processes in a representative national sample of 2031 adults aged 18 to 90 interviewed by telephone in 1990. The negative association between fear and health is explained largely by psychological distress and walking. However, a significant direct effect remains. I conclude with suggestions for future research linking crime and health, focusing on the need for collecting information on community disorganization. Community context is likely the ultimate exogenous variable-the one that sets in motion the destructive cycle of fear, distress, inactivity, and poor health described here. 相似文献

Drawing on the strategic surprise, warning-response, and foreign policy literature, this article argues that the September 11 terror attacks should be regarded as a strategic surprise and examines a number of key factors that contributed to vulnerability and inhibited vigilance. Three broad explanatory "cuts" derived from the literature—psychological, bureau-organizational, and agenda-political—are deployed to sift through the rapidly expanding empirical record in an effort to shed light on the processes and contextual factors that left the United States vulnerable to the attacks. The article aims to improve our understanding of generic processes and practices that enhance or detract from vulnerability and vigilance. 相似文献
