Research on disparities in health and services should include a critical examination of how social, cultural, and contextual factors affect the connection between symptoms and psychiatric disorders. Systematic differences in this connection by these factors will mean that clinicians using a universalist approach to disorders may make more diagnostic errors for certain patients (e.g., ethnic minorities, the poor). Based on the literature on normative clinical decision-making, this study tests for whether the effect of specific psychiatric disorders on key symptoms is the same for certain groups of the population. The data come from the National Comorbidity Survey. Conditional probabilities of disorders and symptoms, the elements feeding into clinical decision-making, are calculated and tested for equivalence across various racial/ethnic, educational, income, and gender groups. We find some significant differences in the relation of key symptoms to disorders across groups. These findings should encourage testing relativistic frameworks in diagnostic nosology as a step to improve clinical decision-making and reduce diagnostic and treatment disparities in mental health services.  相似文献

The utility of brief interventions with at-risk college drinkers would be enhanced if they could also be delivered in group settings without the need for risk prescreening. The current study therefore explored whether components of brief interventions could be effectively administered to mixed groups of drinking and non-drinking students. Specifically, the outcomes of two methods aimed toward increasing motivation for change were compared to controls. One intervention focused on enhancing actual-ideal drinking behavior discrepancy through a structured group discussion, while the other focused on enhancing self-norm drinking behavior discrepancy through the provision and discussion of didactic information. Among at-risk drinkers, significant reductions in heavy drinking episode frequency at four-week follow-up were found for the self-norm (S-N) group only, while reductions in alcohol problems were obtained in both the S-N and control groups. Results suggest that self-norm discrepancy enhancement strategies may be more effective than actual-ideal discrepancy strategies when used with a mixed drinking group.  相似文献

The objective of this article is to assess the effect of abuse cessation on depressive symptoms among women abused by a male intimate partner. This prospective cohort study of Seattle women with a history of intimate partner violence (IPV) who were classified by history of abuse and abuse status at 3 month, 9 month, and 2 year follow-up interviews. Relative risks (RR) were calculated using generalized estimating equations. Among subjects with a history of psychological abuse only, cessation of abuse was associated with a nonsignificant reduction in the likelihood of depression compared to subjects whose abuse continued (aRR = 0.88; 95%CI: 0.75,1.03). Among subjects with a history of physical/sexual abuse and psychological abuse, cessation of physical/sexual abuse only was associated with a 27% decline, and cessation of both types of abuse was associated with a 35% decline in the likelihood of depression (aRR = 0.73, 95%CI: 0.63,0.86; and aRR = 0.65; 95%CI: 0.55,0.76; respectively). Cessation of abuse among victims of IPV is associated with a decreased prevalence of depression.  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

The authors explored the differences between African American and White college students' drinking behaviors and their attitudes toward consequences, harm-reduction strategies, and health information sources. They collected data from a randomly selected sample of 1,110 students in a large public university to examine the effects of a high-risk drinking prevention intervention. In the current analysis, they compared African American and White students on indicators of high-risk drinking, drinking consequences, harm-reduction strategies, the sources that students typically used for health information, and the believability of those sources. The African American students scored lower on drinking measures than the White students did, reported fewer negative consequences, and more regularly employed drinking-reduction strategies, with one exception--choosing a designated driver. Both African and White respondents reported that their parents were their most frequent and usual sources of health-related information and said that parents and health professionals were the most credible sources.  相似文献

This study examined the psychosocial functioning of 100 adolescent females (ages 12-17) sentenced to secure care in a southeastern state and the impact of gender-specific, cognitive-behavioral therapy (CBT) intervention on the psychosocial functioning of subjects who reported a history of sexual abuse. The Multidimensional Adolescent Assessment Scale (MAAS) was used to assess psychosocial functioning. Pre-test scores on the MAAS revealed significantly higher scores on 12 of 16 dimensions of psychosocial functioning and higher rates of serious criminal behavior for youth who subsequently disclosed sexual abuse histories as compared to those without such histories. At post-test, statistically significant improvements in psychosocial functioning were observed on 14 of 16 MAAS subscales for those who received the CBT intervention. Thus, incarcerated female adolescents who reported a history of sexual abuse demonstrated more impairment in their functioning as compared to those without a reported history of sexual abuse and responded positively to gender-specific, CBT-based intervention.  相似文献

Continuous passive motion (CPM) has been proposed as a method to help individuals with low back pain cope with prolonged sitting. The purpose of this study was to investigate the effects that a commercially available CPM device had on lumbar and thoracic erector spinae (ES) muscle activation (using surface electromyography, "EMG"), and on subjective discomfort during prolonged seated computer work with and without the use of the CPM device. There were no significant differences in average ES muscle activation levels, amplitude probability distribution functions, and EMG gaps number and length when sitting with the CPM device was compared to sitting normally. Subjective ratings of discomfort were also not significantly different between the two sitting conditions. The results indicated that there were no clear mechanisms by which the CPM device may reduce ES muscle pain and fatigue for the tasks and pain-free individuals studied.  相似文献
