Abstract

Purpose Evidence supports that physical activity (PA) im- setting and multidimensional outcomes expectations for exer- proves symptoms of multiple sclerosis (MS). Although appli- cise and explained ~14% of the variance in PA (R =0.144, cation of principles from Social Cognitive Theory (SCT) may p < 0.05). Model 2 included walking limitations, fatigue and facilitate positive changes in PA behaviour among people with depression and explained 20% of the variance in PA multiple sclerosis (pwMS), the constructs often explain limit- (R =0.196, p < 0.01). Model 3 combined models 1 and 2 ed variance in PA. This study investigated the extent to which and explained variance increased to ~29% (R =0.288; MS symptoms, including fatigue, depression, and walking p<0.01). In Model 3, exercise self-efficacy (β=0.30, limitations combined with the SCTconstructs, explained more p < 0.05), walking limitations (β=0.32, p < 0.01), fatigue variance in PA than SCT constructs alone among pwMS. (β = −0.41, p < 0.01) and depression (β = 0.34, p < 0.05) were Method Baseline data, including objectively assessed PA, ex- significantly and independently associated with PA. ercise self-efficacy, goal setting, outcome expectations, 6-min Conclusion Findings suggest that relevant MS symptoms im- walk test, fatigue and depression,
