A new measure for assessing the physical activity behaviors of persons with disabilities and chronic health conditions: The physical activity and disability survey

Abstract

Purpose. Assess the psychometric properties of the Physical Activity and Disability Survey (PADS), a new physical activity measure for persons with disabilities and chronic health conditions. Design. Cross-sectional and pre-post designs were employed. Setting. A Midwestern university fitness center. Subjects. Participants were 103 individuals with disabilities and/or chronic health conditions. Measures. The Physical Activity and Disability Survey (PADS), peak oxygen uptake (peak VO2), maximum workload (MW), and time to exhaustion (TE) during exercise. Results. Factor analysis revealed a four-factor model that generally corresponded to PADS subscales. Cronbach alpha coefficients ranged from .67 (Exercise) to . 77 (Time Indoors). Test-retest reliability (1-week interval) ranged from. 78 (Time Indoors) to .95 (Leisure Time Physical Activity). Interrater reliability ranged from .92 (Household Activities) to .99 (Exercise, Leisure Time Physical Activity, Total Activity). Significant (p
