The study purpose was to examine the convergent and discriminant validity of the Leisure Time Physical Activity Instrument (LTPAI). This cross-sectional study included 211 adults with chronic pain from U.S. clinics and community networks. Data were collected on the LTPAI and other similar and distinct self-report measures and assessed using multivariate analysis of variance and bivariate correlations. Physical activity levels were higher in action and maintenance stages for physical activity behavior readiness compared to earlier stages of change. Physical activity was also associated with intrinsic motivation for exercise, self-efficacy for exercise, and exercise outcome expectancy. Light-to-moderate physical activity was higher for normal weight groups compared to overweight groups. These results extend the evidence for the validity of the LTPAI. Given the health benefits of incorporating leisure-time physical activity into daily life, it is important to test the applicability of adapted physical activity measurements among persons most in need of physical activity assessments and interventions.
