Using the Cumulative Common Log-Odds Ratio to Identify Differential Item Functioning of Rating Scale Items in the Exercise and Sport Sciences
Penfield, Randall D.; Giacobbi, Peter R., Jr.; Myers, Nicholas D.
Research Quarterly for Exercise and Sport, v78 n5 p451-464 Dec 2007
One aspect of construct validity is the extent to which the measurement properties of a rating scale are invariant across the groups being compared. An increasingly used method for assessing between-group differences in the measurement properties of items of a scale is the framework of differential item functioning (DIF). In this paper we introduce the concept of DIF as a validation tool for scales used in physical education and exercise science, and illustrate the use of the cumulative common log-odds ratio for assessing the presence of DIF with data from the Exercise Imagery Inventory (EII; Giacobbi, Hausenblas, & Penfield, 2005). (Contains 2 tables and 6 notes.)
