Describes analyses based on 35 studies on effectiveness of Grief Therapy. Clients with no-treatment control groups showed little improvement, possibly because of the relatively long delay between loss and treatment. Client selection procedures appear to contribute strongly to variability in effect size (ESs). The majority of studies involving…

A meta-analysis of instructional research with students with learning disabilities in the domains of word recognition and reading comprehension indicates effect sizes for comprehension measures were higher when studies included derivatives of both cognitive and direct instruction, whereas effect sizes were higher for word recognition when studies…

A meta-analysis of 21 studies compared the effectiveness of computer-assisted instruction (CAI) with traditional instruction. Results showed that CAI focusing on higher-order learning in technical education was more effective. (Contains 38 references.) (JOW)

This meta analysis examines the effect of computer-assisted instruction (CAI) upon college student performance, addresses the impact of various study characteristics upon effects, and explores how media richness theory may predict CAI performance gains. Findings indicate that student performance gains are larger for CAI than traditional…

In their article "Scholars Before Researchers: On the Centrality of the Dissertation Literature Review in Research Preparation", David N. Boote and Penny Beile argue that the literature review is the fundamental task of dissertation and research preparation. They claim that doctoral students receive minimal formal training, and little guidance…

This article is a review of the literature related to the reading attitudes and the instructional methods of teaching reading. The article provides a synthesis of previous studies on the reading attitudes of elementary school students in the United States and also addresses a brief review of literature on historic and traditional methods of…

We conducted a reliability generalization meta-analysis to examine the internal consistency of Dyadic Adjustment Scale (DAS; Spanier, 1976) scores across 91 published studies with 128 samples and 25,035 participants. The DAS was found to produce total and Dyadic cohesion, Consensus, and Satisfaction scores of acceptable internal consistency,…

An early version of this article, discussing curricular interventions in mathematics, was written for the What Works Clearinghouse (WWC). The Institute of Education Sciences (IES), which funds WWC, instructed WWC not to publish it. An expanded version, written at WWC's invitation for a special issue of an independent electronic journal and a book…

Many studies over the last 20--25 years have examined the benefits of mentoring for the protege and the organization. A review of these studies being published revealed that there is not only a lack of studies utilizing or reporting comparison group information but also a general lack of experimental research about mentoring. This quantitative…

The authors investigated the effect of chronic exercise on feelings of energy and fatigue using meta-analytic techniques. Chronic exercise increased feelings of energy and lessened feelings of fatigue compared with control conditions by a mean effect delta of 0.37. The effect varied according to the presence or absence of a placebo control or…

Meta-analyses of studies yielding sex-specific risk of potentially traumatic events (PTEs) and posttraumatic stress disorder (PTSD) indicated that female participants were more likely than male participants to meet criteria for PTSD, although they were less likely to experience PTEs. Female participants were more likely than male participants to…

Religion and spirituality are important aspects of multicultural competency for therapists to consider given the religious culture in America. Researchers have found that more than 90% of Americans claim either a Protestant or Catholic religious affiliation (Keller, 2000), 40% of Americans attend religious services on a weekly basis, and more than…

Background: Attention deficit/hyperactivity disorder (ADHD) is one of the most prevalent and commonly studied forms of psychopathology in children and adolescents. Causal models of ADHD have long implicated dysfunction in fronto-striatal and frontal-parietal networks supporting executive function, a hypothesis that can now be examined…

The performance of methods for detecting publication bias in meta-analysis was evaluated using Monte Carlo methods. Four methods of bias detection were investigated: Begg's rank correlation, Egger's regression, funnel plot regression, and trim and fill. Five factors were included in the simulation design: number of primary studies in each…

A meta-analysis in the form of Brinley plots was conducted on the mean reaction times of Attention Deficit Hyperactivity Disorder (ADHD) and Control groups of children and adolescents on the Stroop Color and Word Test (SCWT). ADHD reaction times were regressed on Control group reaction times for 17 data sets (accessed from 13 published studies).…
