In their zeal for lucrative insurance reimbursement, some private psychiatric hospitals seem to have gone over the edge themselves. A number of these institutions, critics charge, use outright coercion to commit and retain patients. Now some formerly abducted "recruits" are fighting back with lawsuits. 相似文献

This study examines the rapid growth of hospital wage rates and employment levels over the past decade, with particular attention to the period 1971-73, when wage and price controls were in effect throughout the economy. The analysis shows that the hospital regulations under the Economic Stabilization Program reduced real hospital wages below what they would have been in the absence of controls; a similar but smaller effect of the controls on hospital employment levels is also shown. This suggests that if the current HEW proposal for hospital cost containment is enacted, its impact would be a significant decrease in the rate of growth of hospital wages and employment. 相似文献

The purpose of the present study was to examine gender differences in the self-handicapping tendencies of a sample of 337 Australian school attending adolescents, who were aged between 15 and 19 years. Self-handicapping, as measured by the shortened Self-Handicapping Scale, was examined in relation to self-esteem, performance attributions, coping strategies, and the potential behavioral self-handicaps of reduced study hours and inefficient study habits. Girls scored significantly higher on the Self-Handicapping Scale and endorsed using emotional and illness related excuses significantly more often than boys. High self-handicapping scores independently predicted lower study hours for boys, and were associated with less efficient study for girls. Coping and attributional predictors of self-handicapping were found to be rumination, luck attribution, and poor active coping strategies for boys, and ability attributions, behavioral disengagement, instrumental support, and poor active coping strategies for girls. 相似文献

Using data from Wave II of the National Longitudinal Study of Adolescent Health (Add Health; Bearman, P. S., Jones, J., and Udry, J. R. http://www.cpc.unc.edu/projects/addhealth/design.html, 1997), we conducted multivariate analyses to examine three indicators of psychosocial adjustment (school belonging, self-esteem, depressive symptoms) and their associations with sexual attraction status, sex, and urbanicity. In general, sexual minority adolescents reported lower psychological adjustment than adolescents endorsing other-sex attractions only, with sexual minority females at particular risk. Further, differential patterns of risk for sexual minority youth emerged across rural, urban, and suburban communities. We conclude by discussing implications of these findings for addressing the psychosocial needs of sexual minority adolescents. 相似文献
