Meta-analysis is a useful tool for empirically reviewing large bodies of research. It assures that lecture materials are comprehensive and that highlighted studies are supported by a body of knowledge. Many educators are not familiar with the range of topics that has been empirically summarized using meta-analytic techniques. To fill this void, a…

Using meta-analytic techniques, results were synthesized from 58 empirical sources on the association between being married and subjective well-being (SWB). Results indicated that being married was positively and significnatly associated with SWB. However, the magnitude of this association was weaker than expected. (Author/BL)

The homogeneity test provided by L. Hedges (1982) in meta-analysis has been widely used, mainly to test if the effect sizes share the same variance. Ignoring the intercorrelations among effect sizes affects the Type I error rate. The main purpose of this research was to study the impact of pooling effect sizes on the homogeneity test in effect…

Many researchers fail to understand that reliability is a function of scores, not tests. This paper provides an explanation of the distinction as well as a description of the reliability generalization meta-analysis technique. Reliability generalization meta-analysis can provide a way to aggregate test score reliability coefficients from prior…

Examines the use of conceptual frameworks in collecting qualitative data from multiple sites. Presents strategies for devising frameworks that are flexible and general without sacrificing specificity. (JOW)

Conducted a reliability generalization study for the State-Trait Anxiety Inventory (C. Spielberger, 1983) by reviewing and classifying 816 research articles. Average reliability coefficients were acceptable for both internal consistency and test-retest reliability, but variation was present among the estimates. Other differences are discussed.…

Comments on the article by J. S. Hyde (see record EJ733581), which reviewed the results of 46 meta-analyses of studies investigating gender differences and produced results that supported the gender similarities hypothesis that men and women are similar along most psychological traits. The current authors agree with the gender similarities…

The aim of this review was to examine the literature on the effects of surgery of the spastic hand in children with cerebral palsy on functional outcome and muscle coordination. We performed a search of the relevant literature in Medline, Embase, and Biological Abstracts from 1966 to June 2006. The search resulted in eight studies on the effect of…

Background: Burnout has been highlighted as a significant problem for workers in the intellectual disabilities field. A growing number of studies have investigated the levels of burnout and its correlates amongst this population, although they have often reported somewhat contradictory findings. Materials and methods: The present paper sought to…

As scholars and their audiences pursue standards of evidence, standards for literature reviews have also become salient. Many authors advocate "systematic" reviews and articulate standards for these. This article compares the bodies of literature derived from systematic and other types of review, which the author labels conceptual, and…

Three drug and alcohol use screening scales are embedded within the Minnesota Multiphasic Personality Inventory--2: the MacAndrew Alcoholism Scale (MAC) and its revised version (MAC-R), the Addiction Acknowledgement Scale (AAS), and the Addiction Potential Scale (APS). The current study evaluated the reliability reporting practices among 210…

Context: Although there have been substantial advances in knowledge about drug prevention over the last decade, the majority of school-based drug prevention studies have been conducted in urban settings. There is little knowledge about the effectiveness of such programs when they are implemented in rural populations. Purpose: To examine the…

Many have elaborated on the potential of virtual reality (VR) in learning. This article attempts at organizing the literature in this issue in order to better identify indicators that can account for future valid trends, and seeks to bring to attention how authors who wrote about the future of VR in education confused futures' terms and produced…

The 2001 renewal of the United States' Title I program, which provides federal funds to schools with large populations of low-income students, instituted the Supplemental Educational Services (SES) program in which schools in their third year of failing to make Adequate Yearly Progress (AYP) are required to offer after-school tutoring in core…

Meta-analysis was applied to study the empirical research from 1990-2007 regarding the effectiveness of the dating violence prevention programs in middle and high schools on students' knowledge and attitudes. The results show that overall the program participants improved their knowledge and attitudes towards dating violence. Implications for…
