The role of the therapy alliance in therapy outcome for families dealing with child abuse and neglect was examined using the family as the unit of analysis. The alliance was tested as a moderator in relationship to posttreatment levels of symptom distress and physical violence. Results show that the bonds, goals, and tasks subscale scores are significantly related to posttreatment levels of symptom distress and that the goals subscale score is significantly related to posttreatment level of violence. There is an interaction between bonds and level of violence at intake, suggesting that the greater the level of violence at intake, the more important the bonds domain.  相似文献

This survey, with its 85% response rate, provides an extensive profile of drinking behaviors and predictors of drinking among 3,406 members of one national college fraternity, distributed across 98 chapters in 32 states. Multiple indexes of alcohol consumption measured frequency, quantity, estimated blood alcohol concentration levels (BACs), and related problems. Among all members, 97% were drinkers, 86% binge drinkers, and 64% frequent binge drinkers. On the basis of self-reports concerning the 4 weeks preceding the time of survey, the authors found that members drank on an average of 10.5 days and consumed an average of 81 drinks. Drinkers had an average BAC of 0.10, reaching at least 0.08 on an average of 6 days. These fraternity members appear to be heavier drinkers than previously studied fraternity samples, perhaps because they were more representative and forthright. All 6 preselected demographic attributes of members and 2 chapter characteristics were significantly related to the drinking behaviors and levels of risk, identifying possible targets for preventive interventions.  相似文献

Abstract

Objective: To assess knowledge of human papillomavirus (HPV) and perceived barriers to being vaccinated against the virus. Participants: Three hundred ninety-six undergraduate women enrolled at Penn State University in Fall 2008. Methods: A random sample of students were invited to participate in a Web-based survey. Results: Awareness of HPV and the vaccine was high, but knowledge of HPV-related facts averaged only 65% overall. Knowledge was significantly predicted by frequency of media exposure and physician encouragement to be vaccinated, but not by the number of sex partners nor the frequency of condom/dental dam use. On average, women indicated that 2 of the 10 barriers listed applied to them. Physician encouragement negatively predicted barriers at p = .066. No other predictors approached significance. Conclusions: Serious misconceptions remain about specific aspects of the diseases and how they are acquired. Health education efforts are needed to improve knowledge in college populations and counteract perceived barriers.  相似文献

Abstract

The efficacy of brief motivational feedback to reduce drinking among college students has been reported by several researchers. As an extension of this theoretical and applied framework, the author tested the use of mailed feedback to influence the drinking behavior of students self-identified as moderate-to-heavy drinkers in two randomized trials. A 6-week follow-up of the efforts suggested the efficacy of the feedback intervention at reducing alcohol consumption. The feedback mechanism used in the studies is described in detail and possible reasons for its efficacy are explored. In light of the cost-effective nature of this intervention, it may warrant a place in larger campus prevention programs.  相似文献

Self-report data from 594 Latino adolescents about parental involvement (general support, monitoring, academic support, and educational aspirations) and academic motivation were examined across three family structures (intact, stepfather, single-mother/nonresident involved father). Significant differences were found in fathers' but not mothers' involvement depending on the family structure. Dominance analyses showed that the form of mothers' involvement that explained the most unique variance in academic motivation follows: monitoring for youth in intact and single-mother/nonresident involved father families and academic support for youth in stepfather families. The form of fathers' involvement that explained the greatest unique variance in academic motivation follows: monitoring for youth in intact families, academic support for youth in stepfather families, and academic aspirations for youth in single-mother/nonresidential involved father families.  相似文献

This article examines how being the daughter of divorce affects one's marital relationship. We examined this issue by studying the role of the father–daughter relationship in a sample of 90 women, all of whom were currently married and had parents who were divorced, with a Web-based survey. Specifically, this study investigated whether there was a relationship between the strength of these women's relationships with their fathers and the level of commitment, intimacy, and communication in their current marriages. This study produced evidence that the strength of the father–daughter relationship corresponded with current marital intimacy. However, the level of commitment and communication in their own marriages was not linked to the strength of their relationships with their fathers. This study has important implications regarding the work clinicians do to protect and strengthen the father–daughter relationship when working with families who have experienced parental divorce.  相似文献

Although there has always been a general awareness that mathematical expressions must make dimensional sense in terms of the units involved, it is very easy to make simple mistakes in quantitative work that result in profound and potentially dangerous errors. Such errors are ubiquitous in modern research, as can be seen by reviewing government publications where dimensional errors persist despite peer and public review. Software methods have recently become available for checking calculations, equations, algorithms and programs for dimensional soundness. Correctness depends on conformance at two levels: balance of dimensions and agreement among units. Error at either level can now be detected automatically by software. Disagreement among units can even be automatically corrected by software procedures. These software tools can be used to check for errors in calculations and software source code in a way that is similar to using a spelling or grammar checker for text.  相似文献

The provision of social services in rural areas has historically presented a challenge for social workers. Rural social service disparities are presented in relation to key challenges surrounding the provision of social work services in the rural United States. Barriers that define rurality and hinder the provision of social work to rural families, a multicultural examination of rural community strengths and resiliency, and creative solutions for rural social work delivery are discussed. A case study utilizing collaborative partnerships between rural churches, schools, and community leaders to combat rural homelessness and streamline service delivery for rural families across the life cycle is presented.  相似文献
