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

The potential implications for development of professionally defined “standards of care” treatment procedures for mental health counseling are presented. The role of xpert witnesses in malpractice cases is examined as one source from which the standards are currently derived. The influence of managed care on the current clinical practices is noted. Finally, the importance of using outcome research as the basis for developing a “best practices” concept of standards of care is discussed. The authors note difficulties and challenges involved in making a commitment to what could be the next major impetus to the mental health movement. 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
