Results obtained in a metanalysis using indirect alternative methods of computing standardized mean difference effect sizes (SMDESs) were compared with results obtained from direct calculations of SMDESs. In most cases, alternative methods yield very comparable results and are beneficial to use, especially when sample sizes are large. (SLD)

The purpose of this tutorial is to enhance the familiarity and accessibility of meta-analyses in the domains of audiology and speech-language pathology for investigating questions of treatment efficacy and treatment effectiveness. Steps to conducting a meta-analysis are explained and an example of meta-analysis using published data is included.…

The school-counseling outcome research published between 1988 and 1995 is reviewed using the comprehensive developmental guidance model as an organizing principle. Research focused more on remediation than prevention, and tentative support was found for career planning, group counseling, social skill training, and peer counseling. Implications for…

A meta-analysis of 79 studies of reading performance of low achievers with and without learning disabilities found students with the learning disabilities label performed considerably worse on reading measures. Use of timed tests greatly increased the difference in reading performance between underachievers and students with the learning…

Psychological consequences of presymptomatic DNA-testing for Huntington's disease are reviewed. Both carriers and noncarriers experience emotional reactions after disclosure of their test results; however, no long-term adverse emotional consequences have been revealed. Consequences for the family are discussed. Future research should include…

Meta-analysis of 16 studies of expatriate managers' adjustment and 25 of expatriate job performance showed that mean effect sizes were lower than in previous analyses. Cautions about basing cross-cultural training on results of such studies were expressed. (Contains 68 references.) (SK)

Explores implications for evaluation practice of using five different perspectives on organizations, drawing on the four models of social program implementation developed by R. F. Elmore (1978). It is argued that evaluation will only really be effective when its focus, methods, and management reflect realistic assumptions about how organizations…

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)

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…

Numerous studies show that happy individuals are successful across multiple life domains, including marriage, friendship, income, work performance, and health. The authors suggest a conceptual model to account for these findings, arguing that the happiness-success link exists not only because success makes people happy, but also because positive…

One conceptualization of meta-analysis is that studies within the meta-analysis are sampled from populations with mean effect sizes that vary (random-effects models). The consequences of not applying such models and the comparison of different methods have been hotly debated. A Monte Carlo study compared the efficacy of Hedges and Vevea's…

Research concerning the treatment of sexual offenders has generally focused on the treatment of adult offenders. The effectiveness of treatments for male adolescent sexual offenders (N = 644) was assessed in a meta-analysis of 10 studies. Overall, the results were surprisingly encouraging, suggesting that treatments for male adolescent sexual…

This article has three purposes: to explain the two different uses of power analysis that can be used in health education research; to examine the extent to which power analysis is being used in published health education research; and to explain the implications of not using power analysis in research studies. Articles in seven leading health…
