A study examining the effectiveness of wilderness therapy programs for rehabilitating delinquent adolescents analyzed 23 programs using meta-analysis. Moderate effect sizes in favor of wilderness therapy programs were found with respect to enhancing self-esteem/self-concept, improving interpersonal skills, and promoting behavior changes. A small…

Describes a meta-analysis that indicated a slight student preference for a traditional educational format over a distance education format in higher education, and little difference in satisfaction levels, even when considering presence and type of interaction. Discusses meta-analysis as a method for synthesizing literature. (Contains 53…

Conducted a meta-analysis of 74 studies in which there had been an intervention that aimed to improve the behavioral, cognitive, or social functioning of people with attention deficit hyperactivity disorder or attention deficit disorder. Overall, there were larger effects of the various interventions on behavioral than on educational outcomes.…

Presents the results from two meta-analyses of the Mozart Effect studies. Explains that in Christopher Chabris' meta-analyses, 16 studies with subjects (n=714) and 12 studies with subjects (n=522) were analyzed; while in the author's meta-analysis 36 studies with subjects (n=2,465) and 31 studies with subjects (n=2,089) were analyzed.

A synthesis of research on interventions designed to build reading fluency in students with learning disabilities identified 24 studies on various interventions. Results suggested that effective interventions include explicit models of reading fluency, multiple opportunities to read familiar text repeatedly, independently, and with corrective…

Meta-analyses of sex differences in attitudes and affect specific to mathematics found that effects were small in size and similar to sex differences in mathematics performance. When differences did exist, the pattern was for females to hold more negative attitudes than males. However, males held more sex-stereotyped attitudes than did females.…

A meta-analysis of studies conducted between 1974 and mid-1987 on sex differences in mathematical tasks is presented. Methods used include estimations of: (1) parameters for a random effects model, and (2) coefficients for a linear-regression equation, all based on effect sizes calculated from each study. Differences have been decreasing. (TJH)

Summarizes and critiques Asarnow's 1988 review of 24 longitudinal studies identifying environmental factors and individual vulnerability important to development of schizophrenia. Found Asarnow's analysis well conducted but summary should have addressed longitudinal research design. Concludes that identifiable behavior and family interaction…

Uses the results of meta-analyses examining the effects of various message design strategies to evaluate public speaking and persuasion textbooks. Compares the conclusions of the meta-analyses to the conclusions and advice offered by textbooks that rely on social scientific studies. (MG)

Calculated Cronbach's alpha coefficients for five recent studies (N=1,723) which used the Manifest Needs Questionnaire (MNQ) to measure needs for achievement, autonomy, affiliation, and dominance. Results showed acceptable levels of internal consistency for achievement and dominance needs. Found support for autonomy and affiliation needs with some…

While a review by S. Graham (1994) found no differences between blacks and whites on measures of need for achievement, this meta-analysis article found reliable and complex race differences. Overall, whites scored higher on measures of need for achievement, although differences nearly disappeared in studies after 1970. Possible explanations are…

S. Graham comments on taking a meta-analytic approach to reviewing race differences in need for achievement, discussing limitations of the methodology. A rejoinder by H. Cooper and N. Dorr supports the utility of meta-analysis in such studies and discusses disadvantages to narrative review. (SLD)

Experimental studies based on the Dunn and Dunn Learning Style Model (conducted between 1980-1990) were identified to determine the value of teaching students through their learning style preferences. Meta-analysis determined that matching students' learning style preferences with educational interventions compatible with those preferences is…

Integrates findings of nine studies on workplace experiences of lesbian, gay, and bisexual people into five themes: pervasiveness of discrimination, informal and formal types of discrimination, fear of discrimination, worker openness about sexual orientation, and degree of openness versus concealment.

Reexamines the studies of K. S. Dobson regarding metaanalysis of cognitive-behavioral therapy for depression using the Beck Depression Inventory as an outcome measure. Confirms Dobson's conclusions but shows that about half the difference between CT and other treatments was predictable from researcher allegiance. Comparable analysis of a later set…
