The Cochrane Collaboration is an international project to locate, review, and disseminate information on available randomized controlled trials of health care interventions. Occupational therapists can use it to learn about best practices and evaluate research relevant to their clients. (SK)

A meta analysis was conducted of studies examining the relationship between grade point average and salary, with salary as the dependent variable. Results suggest that grades may be meaningful predictors of current salary and somewhat meaningful for starting salary. (SK)

The effectiveness of personal versus systemic-structural social-work practice models is evaluated. Recent independent studies (N=45) are analyzed for differential findings of effectiveness. Client's focus for change (on themselves or on environmental factors) is evaluated in relation to the success of the treatment models. Research needs are…

Provides an integrative review that concentrates on two of the perceived major impediments for integrating science and mathematics: the lack of evidence to support integration, and the lack of a definition for integration. Identifies and defines the forms of integration found from a meta-analysis of 31 studies on integration. (Contains 61…

Performs analysis on a number of articles published between 1985 and 1995 describing experimental research into the effectiveness of a wide variety of teaching strategies for science problem solving. Identifies 22 articles describing 40 experiments that met standards for meta-analysis. Indicates that few of the independent variables were found to…

This article examines the statistical correction for attenuation and the controversies surrounding the procedure. The logic of the double and single correction formulas is discussed, and misapplications and misinterpretations of the correction are presented. (SLD)

Investigates, in two experiments, whether scores on the Role Category Questionnaire (RCQ) predicted the amount of psychological knowledge activated about others. Uses meta-analytic comparison of the results from the experiments to suggest that RCQ scores significantly predict the amount of conceptual psychological knowledge activated about others.…

Conducted a quantitative meta-analysis evaluating the effects of systematic phonics instruction compared to unsystematic or no phonics instruction on learning to read using 66 treatment-control comparisons derived from 38 experiments. Results show that systematic phonics instruction is effective and should be implemented as part of literacy…

A 20-year review of literature on return to work outcomes for ill or injured persons found that research is largely atheoretical and the knowledge base fragmented. The Occupational Competence Model can fill this gap by reflecting the multidimensional nature of work disability (personal, environmental, and occupational dimensions) and factors…

Reports on a survey of eclecticism and integrationism in counselors and other therapists. Results indicate that nearly 87% of counselors reported multiple orientations and approaches alongside a wide range of techniques. Findings suggest that eclecticism and integrationism are the preferred modes of approach, especially for the more experienced…

Maintains that the results of Wellman, Cross, and Watson's meta-analysis on the false belief task are perfectly compatible with "early competence" accounts that posit a specific, innate, and possibly modular basis for theory of mind. Asserts that Wellman and colleagues' arguments against such views stem from mistaken assumptions…

Gender differences in the efficacy of nicotine replacement therapies (NRTs) were examined in a meta-analytical review of 90 effect sizes obtained from a sample of 21 double-blind, placebo-controlled randomized studies. Although NRT was more effective for men than placebo at 3-month, 6-month, and 12-month follow-ups, the benefits of NRT for women…

L. L. Bonatti, M. Pena, M. Nespor, and J. Mehler (see record 2006-06642-010) argued that P. Perruchet, M. D. Tyler, N. Galland, and R. Peereman (see record 2004-21166-008) confused the notions of segmentation and generalization by ignoring the evidence for generalization in M. Pena, L. L. Bonatti, M. Nespor, and J. Mehler (see record…

Effect sizes are critical to result interpretation and synthesis across studies. Although statistical significance testing has historically dominated the determination of result importance, modern views emphasize the role of effect sizes and confidence intervals. This article accessibly discusses how to calculate and interpret the effect sizes…

This meta-analysis reviews 208 laboratory studies of acute psychological stressors and tests a theoretical model delineating conditions capable of eliciting cortisol responses. Psychological stressors increased cortisol levels; however, effects varied widely across tasks. Consistent with the theoretical model, motivated performance tasks elicited…
