A growing body of literature on the subjective experiences of people with severe mental illness (SMI) reveals the importance of the experience of self. The current study explored how the course of SMI is related to individuals' subjective experience of self. Bimonthly, comprehensive, semi-structured interviews with 43 people who had been discharged from psychiatric hospitalization were conducted over a 1-year period. Qualitative analysis of the data revealed mutual influences between the experience of self and illness over time. Conceptual and clinical implications of the relation between self and illness are discussed.  相似文献

Abstact This paper reflects on the results of a national quantitative survey on giving in South Africa. It explores the extent and character of giving; who gives, to whom, with what intention? The survey results revealed that South Africa is richly resourced with a diverse and multicultural spectrum of giving behaviors, which are commonplace in everyday life. The spectrum of giving behaviors is so diverse in shape and form that it contradicts many of the basic assumptions of the philanthropic literature, which locate the act of giving primarily in the domain of the wealthy and powerful.  相似文献

The rate of employment for people with spinal cord injuries is relatively low, especially among Asians. To help individuals with spinal cord injuries return to work or retain employment, rehabilitation professionals must understand the barriers to employment and intervene to reduce or remove them. Hence, a focus group study was administered to 16 people with spinal cord injuries to explore return to work barriers. Various ideas, beliefs, responses, and values at different stages of work resettlement were elicited from both employed and unemployed participants, and then summarized. According to the results, several modifications of existing forms of rehabilitation intervention are necessary, as are further research directions.  相似文献

The literature on racial and ethnic factors in childhood sexual abuse is limited. The purpose of this exploratory study was to document Hispanic-Anglo differences in childhood sexual abuse experiences and assess whether these differences may be explained by socio-demographic and family environmental differences. Adult Hispanic (n = 69) and Anglo (n = 19) women from a family medicine clinic waiting room reporting a history of childhood sexual abuse completed an in-depth survey concerning the sexual abuse experience and their childhood environment. In this study, Hispanics were more likely to report a family member as the perpetrator and to experience more self-blame as a result of the abuse. Hispanics were also more likely to take action in response to the abuse, especially those who were more acculturated to U.S. culture. However, most of the observed differences in this study could be explained by socio-demographic or family environment variables, not by ethnic background. Qualitative research on the family environments of Hispanic victims of child sexual abuse may further explicate the dynamics and risk factors for abuse by family members.  相似文献

Physical activity has been shown to be positively associated with cognitive health, but the mechanisms underlying the benefits of physical activity on cognitive health are unclear. The present study simultaneously examined two hypotheses using structural equation modeling (SEM). The depression-reduction hypothesis states that depression suppresses cognitive ability and that physical activity alleviates dysphoric mood and thereby improves cognitive ability. The social-stimulation hypothesis posits that social contact, which is often facilitated by socially laden physical activities, improves cognitive functioning by stimulating the nervous system. Sedentary behavior in the absence of physical activity is expected to exert an inverse relationship on cognitive health through each of these hypotheses. Community-dwelling elders (N = 158) were administered a variety of measures of cognition, depression, social support, and physical activity. SEM techniques provided partial support for the social-stimulation hypothesis and depression-reduction hypothesis. Implications for treating depression and improving cognitive functioning are discussed.  相似文献

Resistance training has been shown to be the most effective exercise mode to induce anabolic adaptations in older men and women. Advances in imaging techniques and histochemistry have increased the ability to detect such changes, confirming the high level of adaptability that remains in aging skeletal muscle. This brief review presents a summary of the resistance-training studies that directly compare chronic anabolic responses to training in older (>60 years) men and women. Sixteen studies are summarized, most of which indicate similar relative anabolic responses between older men and women after resistance training. Relatively small sample sizes in most of the interventions limited their ability to detect significant sex differences and should be considered when interpreting these studies. Future research should incorporate larger sample sizes with multiple measurement time points for anabolic responses.  相似文献

This research examines excess mortality among American veterans age 70 years or older during a two-to-three year interval from 1993/94 to the end of 1995. Using a structural hazard rate model, we analyzed data on a sample of respondents age 70 or over from the Survey of Asset and Health Dynamics among the Oldest Old (AHEAD). We found that at age 70, older veterans have a slightly higher death rate than their nonveteran counterparts, implying a mortality crossover right before this age. Such excess mortality among veterans increases considerably with age, when other factors are held equal. The direct and indirect effects of veteran status on mortality by means of physical and mental health mostly perform in opposite directions, and such effects vary greatly in magnitude and direction as a function of age. The intervening effects of physical and mental health status decrease substantially with increasing age. Many of the mechanisms inherent in the excess mortality among older veterans are not captured by variations in their health status, especially among the oldest-old. A more extensive study on this topic is urgently needed.  相似文献

Mortality rates in the United States fell more rapidly during the late nineteenth and early twentieth centuries than in any other period in American history. This decline coincided with an epidemiological transition and the disappearance of a mortality "penalty" associated with living in urban areas. There is little empirical evidence and much unresolved debate about what caused these improvements, however. In this article, we report the causal influence of clean water technologies--filtration and chlorination--on mortality in major cities during the early twentieth century. Plausibly exogenous variation in the timing and location of technology adoption was used to identify these effects, and the validity of this identifying assumption is examined in detail. We found that clean water was responsible for nearly half the total mortality reduction in major cities, three quarters of the infant mortality reduction, and nearly two thirds of the child mortality reduction. Rough calculations suggest that the social rate of return to these technologies was greater than 23 to 1, with a cost per person-year saved by clean water of about dollar 500 in 2003 dollars. Implications for developing countries are briefly considered.  相似文献
