Evaluating a Self-Determination Model of Physical Activity and Exercise in People With Chronic Musculoskeletal Pain

Abstract

BackgroundResearch evidence supports the assertion that healthy employees are happier and more productive. Employers prefer to hire healthy workers to reduce absenteeism. Rehabilitation counselors have started to explore health promotion interventions to help individuals with chronic health conditions and disability improve their physical and mental health as a strategy to increase their employment opportunities.PurposeThe present study evaluated a self-determination theory (SDT) model of physical activity and exercise in a sample of 218 individuals with chronic musculoskeletal pain using structural equation modeling.ResultsThe SDT model fit the data well, accounting for 54% of the variance in physical activity and exercise. Relatedness was significantly associated with autonomous motivation for physical activity and exercise. Autonomous motivation was associated with competency. Competency was associated with physical activity and exercise. Autonomous motivation and competency mediated relatedness and physical activity and exercise.ImplicationsThis study contributes to an emerging body of theory-informed health promotion literature and identifies the specific pathways that will increase the motivation to engage in physical activity and exercise. Findings can be used to design and validate theory-driven health promotion interventions as an employment strategy for people with chronic musculoskeletal pain receiving vocational rehabilitation services.
