This article examines the effectiveness of quarterly Recovery Management Checkups (RMCs) for people with substance disorders by level of co-occurring mental disorders (34% none, 27% internalizing disorders, and 39% internalizing and externalizing) across two randomized experiments with 92% to 97% follow-up. The 865 participants are 82% African American, 53% female, and age 37 on average. RMC involves identification of those in need of treatment, motivational interviews, and treatment linkage assistance. It is effective in linking participants in need to treatment, with equal or better outcomes among those with more mental disorders. The data support the utility of monitoring and re-intervention for clients with co-occurring disorders.  相似文献

Empirical Bayes methods are used to estimate cell probabi-lities under a multiplicative-Interaction model for a two-way contingency table. The methods assign uniform and normal priors with unknown variances to the main effects and the separable scores. A priori the analysis assumes exchangeability of sets of parameters. The unknown variance components are estimated empirically from the data via the EM algorithm as discussed by Laird (1978)and Dempster, Laird and Rubin (1977). An example Is Included.  相似文献

Social network sites (SNSs) are a powerful new context for adolescent development. We qualitatively investigate African American adolescent boys’ (N = 50, mean age = 15.8) perceptions of emotional display rules on SNSs. We present and discuss a taxonomy of display rules for anger, sadness, embarrassment, and excitement. Perceived display rules around anger and sadness were most notable. Participants’ understandings of display rules around anger were complex and varied, with many describing threats of violence as marking the line between acceptable and unacceptable expressions. Although youth stated that expressing sadness via SNS could garner emotional support, this was understood somewhat consistently as unacceptable. Overall, our findings suggest that perceptions of emotional display rules on SNSs are varied, complicated, and can be difficult to navigate.  相似文献

The literature and events related to the politicization of emergency contraceptive pills (ECPs) in the United States is reviewed. The basis of opposition to the regimen, rooted in the mode of action of ECPs, the confusion with mifepristone, and the challenges this presents for ECP advocates is also discussed. Legislative actions that impact the availability of ECPs are described, as well as efforts to increase access and availability through innovative programs, legislation, and changes in medical practice. Recommendations for future research, service delivery, and public policy are also presented .  相似文献

Traditional conceptualizations of parenting style assume certain associations between parenting practices/philosophies and parental warmth. This study examines whether those links are similar for European American and African American adolescents. Two hundred and ninety‐eight early adolescents and their mothers reported on discipline and control practices, decision‐making practices, and parenting philosophy, which were used to predict adolescents’ reports of maternal warmth. The moderating role of ethnicity was examined after controlling for gender, age, and socioeconomic status. Although some practices predicted warmth similarly across groups, several practices predicted warmth in ways consistent with parenting style theory only or more strongly among European American adolescents. The findings suggest differences in the interpretation of or context surrounding discipline‐ and autonomy‐related practices in these groups.  相似文献
