The purpose of the present study was to characterize the psychopathology measured ten years posttreatment in 51 women who had an adolescent onset of anorexia nervosa. Outcome status was determined using the modified categories of Ratnasuriya et al.[1991]. Anorexia Nervosa: Outcome and Prognostic Factors After 20 Years, British Journal of Psychiatry, Vol. 158, pp. 495–502). Psychopathology was assessed using a number of self-report questionnaires: Beck Depression Inventory, Hamilton Depression Inventory, Leyton Obsessionality Inventory, Social Adjustment Scale, and Minnesota Multiphasic Personality Inventory. Within this adolescent age of onset sample of anorexia nervosa, age of onset was not, in and of itself, associated with increased psychopathology at follow-up. Rather, severity of eating disorder outcome was associated with general psychopathology, with patients in the poor outcome group displaying elevations on several of the measures of psychopathology.Received Ph.D. in psychology from Rutgers Univesity. Major research interests are in eating behavior and attitudes toward foods in anorexia and bulimia nervosa, preoccupations and rituals associated with eating disorders, and comorbidity and eating disorders.Received M.D. from the University of Medicine and Dentistry in New Jersey.

In the three years since the Americans with Disabilities Act (ADA) was enacted, significant developments have occurred in the form of new administrative and judicial interpretations of the Act. The new guidelines and decisions will assist employers in complying with the ambiguous, and sometimes confusing, provisions of the ADA. Recent developments in areas such as the definition of a disability and the permissibility of medical inquiries, along with continuing developments in the areas of mental disabilities and defining reasonable accommodations, give employers insight into the obligations created by the ADA. These developments are a good starting point to understanding the ADA, but there is still a long way to go. This article surveys the recent developments in the law and examines the considerations that have become important to the Equal Employment Opportunity Commission and the courts in interpreting the ADA's provisions. 相似文献
