This study uses Cox regression to assess the relationships among parental drug use, drug treatment compliance, and reunification from substitute care. The study finds that drug treatment compliance is associated with faster reunification, even when accounting for ongoing drug use and three parenting measures. The findings are consistent with a conceptual framework suggesting that certain client actions, such as drug treatment compliance, may serve as markers that substantially affect client outcomes. 相似文献

Despite alcohol server training programs and legal liability aimed at controlling intoxication, server intervention appears to be rare. Given the difficulty in assessing intoxication, it can be assumed that improvement in assessment skills would increase the likelihood of intervention. Unfortunately, little is known regarding practices servers use to identify intoxication. In order to build a more informed base for policy formation and server training, the focus of this inquiry was to examine practices used by servers to assess intoxication. The analysis was based upon questionnaires mailed to a random probability sample of licensed servers from one state (N = 822). Indicators found to be most important were examined in relation to a variety of occupational characteristics. Implications for training curricula, policy formation, and future research are discussed. 相似文献

Proponents of social norms approaches maintain that correcting misperceptions of alcohol use among college students may reduce drinking and its consequences. The author used aggregate campus-level data from the Nationwide Campuses Study to test this hypothesis. He defined the misperceptions ratio as the ratio of the frequency of the "average student's" perceived alcohol use to the frequency of self-use at each campus. Each of the 57 colleges reported misperceptions ratios greater than unity. At campuses where students had more accurate perceptions of alcohol use, students were more likely to desire alcohol availability at campus events and to drink on more days throughout the year than at campuses where students had greater misperceptions of alcohol use. The author found no data to support the preferential use of social norms programming on campuses with high levels of self-reported alcohol use or binge drinking. These findings raise questions about potentially unexpected and unintended effects of social norms approaches. 相似文献

This article describes the third phase of a research study undertaken within a Canadian provincial regional health authority to explore and analyze mental health services and other resources used by rural consumers after discharge from inpatient mental health programs. The focus of this article is the qualitative research findings obtained from mental health service providers and members of allied agencies. This article will discuss the literature on rural consumers' access and use of mental health programs and services; describe the context and method used to conduct the focus groups with rural service providers; characterize access and use problems from the service providers' perspectives; and suggest strategies to address these problems. 相似文献

This study evaluated the relationship between employment status (i.e., part- and full-time) and job satisfaction, with the focus on the moderating roles of perceived injury risk and injury incidence. The results found that the level of job satisfaction for full-time workers was about the same regardless of the level of injury risk they perceived. In contrast, job satisfaction of part-time workers was significantly higher when they perceived low injury risk rather than high injury risk. The findings also supported the potential adverse impact of injury incidence and injury risk on job satisfaction for both part- and full-time workers. This study highlighted the importance of understanding both workplace safety and job satisfaction when attempting to understand the differences between part-time and full-time workers. 相似文献

The 'accessible' job market of the 1990's has given way to a challenging job market in a climate of economic uncertainty in the early Twenty-First Century. For vocational rehabilitation professionals this change requires the strategic use of workplace supports to increase the value and sustainability of work performed by people with disabilities in competitive jobs. An analytical framework for leveraging the natural supports of the workplace is provided by the workplace ecology as a bounded environment in which relationships between workers and supervisors promote learning and enhanced performance. The dynamics of the workplace ecology are explored with particular reference to workers with disabilities receiving supported employment services. Recommendations are made for leveraging the workplace ecology to the benefit of the supported worker. Implications for supported employment services in the new millennium are discussed. 相似文献

The attempt to recover gambling losses by continuing to gamble (chasing) has featured prominently in accounts of excessive gambling. This research represents the first attempt to operationalize and measure chasing in terms of its cognitive (behavioral intention), emotive (urges) and behavioral components, and to investigate the role of chasing in relation to impaired control over gambling. Two survey samples of 84 male off-course (betting shop) race gamblers (mean age 41, SD = 15) and 137 gaming machine players (73 females, mean age 48, SD = 15 and 64 males, mean age 43, SD = 16) were recruited at gambling venues. Respondents completed a structured questionnaire that investigated retrospective report of chasing and an impaired control scale (The Scale of Gambling Choices). It was found that the various components of chasing formed a composite measure with high internal reliability that was strongly related to indicators of excessive gambling (e.g. time spent gambling, expenditure as a proportion of income) and to impaired control scores. Reacting to large wins by further betting was almost as strongly related to impaired control as was persistence after losing. Those who returned later to chase had significantly higher impaired control scores than those who only chased within a session. Alcohol-related chasing was associated with impaired control over gambling. Chasing of losses and impaired control appear to be generic processes in evidence across both forms of gambling and gender (most format and sex differences were of minor significance). 相似文献

The prevalence of diagnosed cumulative trauma disorders (CTD) within the workforce comes at a high price for employers burdened with financial losses from missed work and worker's compensation costs. Research has focused primarily on the impact of CTD on the worker role within the workplace, overlooking the impact on roles across multiple environments [24,35,54]. Furthermore, the influence of CTD on life roles of a spouse has not been examined. This single case study illustrated the experience of CTD within a marital relationship through the use of grounded theory. Results indicated that adaptations to CTD symptoms were least altering to the established routines and roles of the couple. With progression of symptoms, the spouse without symptoms was relied on more heavily for adaptations to manage pain. The results of this study indicate that occupational therapists must examine the client's valued roles and incorporate the family into intervention strategies. 相似文献

The article examines issues involved in comparing groups and measuring change with pretest and posttest data. Different pretest-posttest designs are presented in a manner that can help rehabilitation professionals to better understand and determine effects resulting from selected interventions. The reliability of gain scores in pretest-posttest measurement is also discussed in the context of rehabilitation research and practice. 相似文献
