Abstract
This study investigated the appropriateness of the Health Action Process Approach (HAPA) as it relates to physical activity (PA) behavior in the back pain population. The motivational and volitional constructs of the HAPA, PA, and back pain-related disability variables were assessed in a sample of 350 men and women with back pain. HAPA model fit was satisfactory accounting for 21% of the variance in PA intentions and 28% of PA behavior. All motivational phase constructs relate to PA intention. Action/coping planning and recovery self-efficacy do not relate to PA behavior. PA intentions are the strongest predictor of PA behavior. An expanded model, including disability-specific variables, satisfactorily fit the data, accounting for 32% of PA intentions and 29% of PA participation. These data partially support assumptions of the HAPA for the back pain population. For the back pain population, interventions designed to affect PA behavior must account for disability-specific variables.
