The purpose of this study was to examine in a sample of 11,516 secondary school students the extent to which different behavioral, emotional and cognitive problems (a) reflected one or more underlying common factors; (b) actually cooccurred; and (c) were single problems. Principal Component Analyses were performed and percentagewise techniques were used. PCA demonstrated that one or more general syndromes could not by far account for all of the variance of the variables. The results suggest the existence of adolescent subgroups with divergent comorbidity patterns: those who primarily report one single symptom; those who report concurrent symptoms either exclusively in the category of behavioral problems or exclusively in the category of emotional and cognitive problems; and those who report concurrent symptoms in both categories. This distinction between different subgroups has important theoretical, diagnostic, and treatment implications.  相似文献

The present research explored factors thought to affect compensatory awards for non-economic ham (pain and suffering) in personal injury cases. Experiment 1 showed that the nature and severity of the plaintiffs injury had a strong effect on perceptions of the extent of harm suffered and on award amounts. The parties' relatively active or passive roles in causing the injury affected assessments of their degree of fault, but perceived fault had little influence on awards. Experiment 2 replicated with more varied cases the strong impact of injury severity on harm perception and on awards for pain and suffering. In both studies, the disability and the mental suffering associated with injuries were stronger predictors of awards than were pain and disfigurement.  相似文献

Due to the high cost of health care claims and COBRA's status as remedial legislation, COBRA has generated a significant amount of litigation in recent years. While the early COBRA decisions tended to broaden the law in order to provide a remedy to an otherwise uninsured qualified beneficiary, the recent trend in the case law has been to limit the expansion of COBRA rights based on a narrower construction of the statute. Even so, COBRA still represents a legal minefield for employers. As a result, a careful employer will minimize its exposure by monitoring changes in the law and its interpretation and making appropriate modifications to its COBRA documentation and administration. This article discusses some of the more significant recent changes in the law affecting qualified beneficiaries' COBRA rights--and therefore, employers' exposure.  相似文献
