The purpose of this study is to evaluate the extent to which a model of social support may help explain the low suicide rate of Black females. The data are taken from the National Institute of Mental Health's Epidemiologic Catchment Area Study 1980–1985 (United States). The LISREL model examines the direct and indirect effects of the background characteristics on attempted suicide as mediated by emotional state. Results indicate evidence that for Black and White males and females, finding emotional and psychological support in friends and family members helps to safeguard against suicide. The most substantial finding is that for all race/sex categories, seeking support from friendship and familial resources is negatively related to attempted suicide, whereas seeking support from professional resources is associated with an increase in the likelihood of a suicide attempt. This increased likelihood of attempted suicide may be reflecting populations members' resistance to seeking professional help until their emotional state has severely deteriorated. 相似文献

Research has consistently shown that children with severe conduct problems often exhibit intellectual deficits, especially in their verbal abilities. We investigated whether or not this finding only applies to certain subgroups of children with severe conduct problems. In a sample of 117 clinic-referred children between the ages of 6 and 13, we assessed for Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD) symptoms using a structured diagnostic interview with each child's parent and teacher, callous and unemotional traits using parent and teacher ratings, and intellectual functioning using a standard individually administered intelligence test. Children with an ODD or CD diagnosis who did not show callous and unemotional traits showed a deficit on subtests measuring verbal reasoning ability relative to a clinic control group. Children with an ODD or CD diagnosis who also showed callous and unemotional traits did not show a verbal deficit and, in fact, showed a trend toward having weaker nonverbal abilities. These results highlight the importance of recognizing distinct subgroups of children with severe conduct problems when studying potential intellectual deficits in these children. 相似文献

The preceding commentary by Louis Charland suggests that traditional cognitive views of decision-making competence err in not taking into account patients' emotional capacities. Examined closely, however, Charland's argument fails to escape the cognitive bias that he condemns. However, there may be stronger arguments for broadening the focus of competence assessment to include emotional capacities, centering on the ways in which emotions aid humans in processing information. Before emotional capacities are added to the list of functions essential for decisional competence, though, the feasibility and utility of such a reorientation must be demonstrated. 相似文献

Genetic testing for inherited cancer susceptibility, based on the recently identified. BRCA1 and BRCA2 genes, will soon be available on a large scale. However, at present, genetic test results do not lead to clearly indicated diagnostic or preventive measures, and the nature of the psychological impact of BRCA1/2 testing is still largely unknown. This uncertainty, combined with preliminary evidence suggesting significant individual differences in reactions to genetic susceptibility feedback, constitutes a unique challenge for any individual contemplating such testing. We outline the nature of this challenge and then propose an intervention strategy designed to help individuals make deeply processed and psychologically well-informed decisions with regard to their genetic susceptibility. The intervention is guided by recent research findings and theory on the cognitive–emotional processing of cancer-risk information. Specifically, the goal is to prepare the individual for genetic testing by (1) cognitively and emotionally activating, or preliving, the individual's potential reactions to testing feedback; (2) facilitating accurate appraisal of the individual's cognitive–emotional reactions; and (3) enabling the individual to process these reactions through the use of well-established clinical techniques. 相似文献
