The Reliability and Validity of Test Scores: Are Editorial Policy Changes Reflected in Journal Articles?
Witta, E. Lea; Daniel, Larry G.
In 1994, the journal "Educational and Psychological Measurement" (EPM) instituted an editorial policy requiring authors to use technically appropriate language and methodological practices in their discussions of validity and reliability. To determine if this policy has had any effect on current publications, 150 validity and reliability studies were selected from 3 social science measurement journals ("EPM,""Psychological Assessment," and "Journal of Psycheducational Assessment") over a 3-year period (1995 through 1997). Language usage and methodological problems in these studies were compared to the same problems as reported in a previous study of 150 articles selected from the 3 volume years of the same journals immediately preceding the EPM editorial policy. Results indicate a statistically significant decrease in incidence of errors across time. Before the 1997 editorial, 108 of the 150 studies (72%) contained 1 or more errors, but after publication of the editorial, approximately 51% (77 of 150) analyzed contained 1 or more errors.
