Developing an instrument to measure physical activity related self-worth in women: Rasch analysis of the Women's Physical Activity Self-Worth Inventory (WPASWI)

The objective of this study is to report on the development of an instrument to assess non-physical aspects of physical activity (PA)-related self-worth (SW). Three hundred thirty five women (mean age=36.69±15.94 yrs, BMI=24.87±4.56) completed the Women's Physical Activity Self-Worth Inventory...

Description
Summary:The objective of this study is to report on the development of an instrument to assess non-physical aspects of physical activity (PA)-related self-worth (SW). Three hundred thirty five women (mean age=36.69±15.94 yrs, BMI=24.87±4.56) completed the Women's Physical Activity Self-Worth Inventory (WPASWI), General SW Scale, and a PA Questionnaire. Rasch analysis was used to evaluate the WPASWI. Three PA-related SW subscales were identified: PA Knowledge (16 items), PA Emotional (13 items), and PA Social (8 items). Rasch analysis supported construct validity, and items demonstrated acceptable internal consistency (Cronbach's alpha=0.90, 0.87 and 0.72) and test-re-test reliability (r=0.79, 0.70, 0.81). Women who reported regular PA participation had higher PA Knowledge, PA Emotional, PA Social, and General SW than those who reported some or no PA (p
