The purpose of this study was to determine the effectiveness of an Employee Assistance Program (EAP) in terms of selected work performance indicators and treatment outcomes. Three primary data sources were utilized: a questionnaire administered to EAP users, reports from EAP counsellors on treatment diagnoses and outcomes, and employee records on absenteeism and other performance criteria over a five year time period. On the whole, EAP clients reported very favourable outcomes regarding the quality of services and improved well being, and the counsellors reported successful treatment outcomes. However, employee records on performance outcomes indicated that EAP clients had higher rates of problems before, during and after treatment, compared to a matched control group. Additionally, rates of sick days significantly increased from before to after treatment among EAP users.  相似文献

When evaluating the effectiveness of an educational program, a sampling strategy known as “multiple matrix sampling” is particularly effective and efficient when the goal of the evaluation is estimating group (as opposed to individual) performance. Although this technique involves sampling both program participants and items and, subsequently, different participants being assessed over different sets of items, the results may be used to estimate those which would have been obtained had all participants been administered all items. The technique is here described in some detail, with advantages and disadvantages discussed, and examples of its application are given.  相似文献

Abstract

This article describes the development, validity, and reliability of the Parent Empowerment and Efficacy Measure (PEEM). Development was guided by theory and by challenges faced by Pathways to Prevention family support staff who required a short, practical, and reliable measure of parent empowerment. The measure's psychometric properties were tested using data from 866 parents of children aged 5 to 12, living in high to low socioeconomic status areas. Principal factor analysis revealed a strong general dimension with high internal consistency (α = 0.92) that correlated at 0.60 or more with three validation measures, as well as the existence of two hypothesised subfactors (correlated at 0.78): efficacy to parent and efficacy to connect, each with internal consistencies of 0.85+. Test–retest reliability (n = 200) was 0.84. PEEM exhibits excellent convergent and concurrent validity and is a reliable tool for use in planning services, monitoring participant progress, and evaluating program effectiveness.  相似文献

Was the divorce plateau of the 1980s experienced by people of all incomes? Using the 2001 and 2004 Survey of Income and Program Participation, this study (N = 13,131) examined if there was a significant income class difference in marital dissolution within 10 years of first marriage and if this difference increased from the late 1970s to the early 1990s. The findings indicated that there was a significant income class difference in marital dissolution and that the difference was growing during the study period. Whereas the dissolution rates of higher income women had gone down, the rates for women with the lowest incomes had significantly increased, especially for Black women after the 1980s, indicating a diverging trend in marital dissolution by income status.  相似文献

The purpose of this study was to explore students’ and staff members’ understandings of bullying and related social constructs within a U.S. high school. Students (N = 84) participated in interviews and focus groups; students (N = 797) and staff members (N = 77) completed surveys. The qualitative data were analyzed using a grounded theory approach, and the findings were used to inform the development of survey items, which were analyzed using a one-way ANOVA. Findings from both components of the study were merged during interpretation. Results suggest that the school’s social environment reflects a complicated milieu in which it is difficult to apply a research definition of bullying to problematic student social interactions. A theoretical model of how conflict, drama, aggression, and bullying are related is proposed.  相似文献

Research has documented heterosexism and genderism facing lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQQ) students in schools, especially as it relates to experiencing bullying and harassment. However, little research addresses anti-LGBTQQ bullying interventions, and no research has examined the use of youth-led performance and dialogue in cultivating anti-bullying behaviors among students. The present mixed-methods study assesses one such intervention led by a community-based LGBTQQ and allied youth group. Repeated measures general linear modeling demonstrates a positive impact of this intervention on middle and high school students' likelihood to intervene when witnessing anti-LGBTQQ harassment and confidence to successfully do so, particularly for White students. Qualitative findings demonstrate barriers to intervention and decision-making processes of youth when intervening. Results suggest the importance of these interventions in empowering LGBTQQ youth to effect change in their schools.  相似文献

我国政府投资项目集中管理模式的出现,将原来由各建设单位分散建设管理的项目转变为由政府建设管理部门集中管理。这种大规模和集成化的建设管理模式相应地使更为强大的信息管理和信息沟通系统的出现就成为了必然的需要。近年来出现的项目群管理理论是项目管理理论的重大突破,为项目信息管理和优化提供了切实可行的指导思路。研究表明,深圳市建筑工务署通过分析项目群信息系统构建要求、分层次管理和沟通要求后建立的项目群管理信息管理和信息沟通系统,实现了项目群管理的优化。  相似文献

This study evaluates the effectiveness of a truancy reduction program. A Regression Discontinuity design was used to assess attendance outcomes for 700 children. Approximately half received a case management intervention, while the other half received a warning letter, only. Truancy rates in the control group remained at the pre-intervention levels, while truancy in the treatment group significantly declined (p < .01). Successful case closure was associated with a reduction in truancy (p < .001). The intervention was less effective with non-White children and with those who had been previously retained. Findings substantiate continued support for the intervention; however, additional resources should include culturally-responsive treatment approaches and academic enrichment programs.  相似文献
