Description of Research Report: Power, Effect Size, and Practical Significance: How the Reporting in Journal of Visual Impairment & Blindness Articles Has Changed in the Past 20 Years

The topics of effect size and statistical power have been neglected in social science research for many decades despite their importance. Partly helped by the American Psychological Association's (2001) call for reporting effect sizes, some journals have started to make efforts to require their authors to report or interpret effect sizes and indicate whether the selected study design allowed sufficient statistical power to detect a target effect size of the intervention. However, many journal editors and reviewers still seem to be neglecting this topic (Fritz, Morris, & Richler, 2012). This neglect is of serious concern, because the appropriate use of and interpretation of effect size, along with information on statistical power, is essential in determining practical (clinical) significance of any applied research findings (Fritz et al., 2012; Keselman et al., 1998).
