    Journal: Res Nurs Health; 2006 Dec; 29(6):597-606. PubMed ID: 17131278.
    Abstract:
    Using social-cognitive theory, we examined the associations among symptoms, self-efficacy, and physical activity in 196 individuals with multiple sclerosis (MS). Participants completed symptoms, self-efficacy, and physical activity measures and wore an accelerometer for 7 days. There was a moderate inverse correlation between symptoms and physical activity (varphi = -.42). Subsequent analyses indicated that symptoms had direct negative relationships with self-efficacy (gamma = -.32) and physical activity (gamma = -.24), and self-efficacy had a direct positive relationship with physical activity (beta = .57). This study provides initial support for symptoms as a correlate of physical activity in individuals with MS. Monitoring symptoms during a physical activity program and altering the exercise prescription during symptom exacerbation might be a method for increasing exercise adherence.
