Objective: The purpose of this study was to examine the impact of perceived functional abilities and health promotion activities on subsequent symptom experience among those who have lived with multiple sclerosis (MS) for many years. Methods: This longitudinal mailed survey study examined Health Promoting Lifestyle Profile II (HPLP) scores and MOS SF 36 scores as predictors of PROMIS® Pain Interference, Pain Intensity, Fatigue, Sleep Disturbance, and Applied Cognition Abilities Scores among 260 adults with MS. The community dwelling sample was initially recruited from the mailing list of the MS Society in a large southwestern state. Respondents were predominantly female, with an average age of 67 years. They had been diagnosed an average of 30 years. Forty percent reported relapsing remitting MS, and 41% have the more severe progressive form of the disease. Results: HPLP and SF 36 Role Physical, Role Emotional, and Social Function scores assessed in 2013 were moderately correlated (r > .30) with PROMIS® Fatigue and PROMIS® Cognitive Abilities scores measured in 2014 and were somewhat predictive of PROMIS® Pain and Sleep Disturbance scores (r > .20). These results were replicated in an analysis using data from Years 2016 and 2017. Conclusions: Findings suggest that those who report higher levels of health promotion activities and greater functional ability may experience lower levels of fatigue, pain, and sleep disturbance and higher levels of cognitive abilities in the subsequent year.
