Although empathy has been found to distinguish effective counsellors from less effective counsellors, human services professionals who continually experience negative emotional reactions to the feelings that clients express in counselling may be at risk of developing burnout. This study examined the hypothesis that emotional empathy rather than cognitive empathy is associated with burnout. The sample of human services professionals consisted of 71 Salvation Army Officers. Multiple regression was used to investigate whether the dimensions of empathy could predict three aspects of burnout: personal accomplishment, emotional exhaustion and depersonalization. The first regression analysis indicated that personal distress and empathic concern were significant predictor of personal accomplishment. The second analysis indicated that personal distress was a significant predictor of emotional exhaustion. The third indicated that empathic concern was a significant predictor of depersonalization. Although these results support the hypothesis, personal distress was negatively associated with personal accomplishment, whereas empathic concern was positively associated with personal accomplishment. The small size of the sample may have influenced the reliability of the findings. A multidimensional approach to the role of empathy in counselling may help human services professionals to manage their emotional reactions when they engage in counselling with distressed clients.  相似文献

The goal of Louisiana's 1990–1991 comparative risk project, also called the Louisiana Environmental Action Plan (LEAP), was to incorporate risk assessment into state environmental planning and policymaking. Scientists, government officials, and citizens were brought together to estimate the relative risk to human health, natural resources, and quality of life posed by 33 selected environmental issues. The issues were then ranked according to their relative estimated risks. It was hoped that this ranking of "comparative risks" would enable state policymakers to target the most important environmental problems and allocate scarce public resources more rationally and efficiently. As a result of the project, the governor issued an Executive Order forming a permanent Public Advisory Committee to continue this type of comparative risk assessment in Louisiana.  相似文献

Since children, particularly daughters, are among the most important sources of help and support for older Americans, it has been suggested that women's increasing employment will affect filial relations. Empirical evidence on this issue is inconsistent, in part due to the use of nonprobability samples. Few studies have measured effects for men. We attempt to broaden the scope of this question beyond help to the frail elderly by asking whether employment affects filial relations in general. We examine effects of hours employed on telephone contact, visiting, feelings of closeness, filial attitudes, and assistance to biological parents, for an area probability sample of men and women over 40. There are no effects of employment for men or women on contact, closeness, or assistance. For the vast majority of this population sample, contact and assistance involve few hours per week, and thus do not seem to conflict with employment.  相似文献

This report summarizes the proceedings of a conference on quantitative methods for assessing the risks of developmental toxicants. The conference was planned by a subcommittee of the National Research Council's Committee on Risk Assessment Methodology 4 in conjunction with staff from several federal agencies, including the U.S. Environmental Protection Agency, U.S. Food and Drug Administration, U.S. Consumer Products Safety Commission, and Health and Welfare Canada. Issues discussed at the workshop included computerized techniques for hazard identification, use of human and animal data for defining risks in a clinical setting, relationships between end points in developmental toxicity testing, reference dose calculations for developmental toxicology, analysis of quantitative dose-response data, mechanisms of developmental toxicity, physiologically based pharmacokinetic models, and structure-activity relationships. Although a formal consensus was not sought, many participants favored the evolution of quantitative techniques for developmental toxicology risk assessment, including the replacement of lowest observed adverse effect levels (LOAELs) and no observed adverse effect levels (NOAELs) with the benchmark dose methodology.  相似文献
