Predictors of exercise behaviors among fibromyalgia patients.

BACKGROUND
Exercise improves the physical and psychological well being of patients with fibromyalgia syndrome (FMS). However, exercise interventions for patients with FMS have suffered from poor adherence. The purpose of this study was to examine predictors of exercise for people with FMS.


METHODS
Participants were 444 patients with FMS who were part of a larger study. Hierarchical logistic regression analyses were conducted examining exercise behavior at multiple time points. Discriminant analyses were also used to identify predictor variables.


RESULTS
Engaging in regular exercise and having higher exercise self-efficacy significantly predicted continued engagement in exercise behavior in people with FMS. Age, employment status, depression, education level, self-efficacy for managing FMS, and the size of one's social network also demonstrated predictive qualities.


CONCLUSION
Exercise self-efficacy and continued participation in regular exercise most strongly predicted present and future exercise behavior in patients with FMS. Interventions designed to train FMS patients in initiating exercise programs while addressing exercise self-efficacy, depression, and social support are warranted.
