Effect-size reporting practices in AJSLP and other ASHA journals, 1999-2003.

A census of effect-size practices in the past 5 volumes of American Speech-Language-Hearing Association journals was accomplished. Inclusion of effect size in quantitative research reports increased from 5 reports with effect size in 1990 to 1994 to 120 reports in 1999 to 2003. Nonetheless, effect size was reported less than 30% of the time when inferential statistics were used, and only half of those reports included an interpretation of effect size.

Problems in synthesis (meta-analytic) studies: an example from the communication disorders literature.

This research note examined contemporary issues for meta-analysis with an example from the communication disorders literature. A significant proportion of experimental and quasi-experimental research results are not published in the mainstream literature, which suggests that publication bias is a potential problem for synthesis studies. Nonetheless, 50% of synthesis studies (meta-analyses) in communication disorders do not include statistical or visual procedures, e.

Evidence-Based Practice in Schools: Evaluating Research and Reducing Barriers.

This article examines the clinician/researcher relationship, suggests directions for improving the relationship, and discusses avenues for transferring information from research to clinical practice. An eight-step model for transferring research studies to practice is adopted, and three of the eight steps are targeted for discussion and illustration. To illustrate the use and interpretation of effect size measures for practical significance, as well as the transfer of research results to practice (evidence-based practice [EBP]), a case study from the contemporary literature is presented.
