Abstract

Aims The aims of the study were to examine the differential item functioning (DIF) of the Tendency of Avoiding Physical Activity and Sport Scale (TAPAS) among three subgroups (gender, weight status, and region) and to test the construct and concurrent validities of the scale. Methods Using an online survey, university students (608 Taiwanese and 2319 mainland Chinese) completed the TAPAS. Rasch analysis examined if all the 10 TAPAS items fitted the same construct and displayed no substantial DIF across three subgroups: gender (male vs. female), weight status (overweight vs. non-overweight), and region (Taiwan vs. China). Concurrent validity was examined using the scores on the Weight Self-Stigma Questionnaire (WSSQ) and Weight Bias Internalization Scale (WBIS). Results All TAPAS items, except for Item 10 (“Prefer to participate in physical activity in a more private setting”), fitted the same construct. None of the TAPAS items displayed DIF in any of the subgroups except for Item 10 across participants from Taiwan and China (DIF contrast = −1.41).
