PURPOSE: To explore the relationship that cognitive behavioural and other
previously identified variables have with physical activity engagement in people
with multiple sclerosis (MS). METHODS: This study adopted a cross-sectional questionnaire design. Participants were 282 individuals with MS.
Outcome measures
included the Physical Activity Disability Survey--Revised, Cognitive and
Behavioural Responses to Symptoms Questionnaire, Barriers to Health Promoting
Activities for Disabled Persons Scale, Multiple Sclerosis Self-efficacy Scale,
Self-Efficacy for Chronic Diseases Scales and Chalder Fatigue Questionnaire.
RESULTS: Multivariable stepwise regression analyses found that greater
self-efficacy, greater reported mental fatigue and lower number of perceived
barriers to physical activity accounted for a significant proportion of variance
in physical activity behaviour, over that accounted for by illness-related
variables. Although fear-avoidance beliefs accounted for a significant proportion
of variance in the initial analyses, its effect was explained by other factors in
the final multivariable analyses. CONCLUSIONS: Self-efficacy, mental fatigue and
perceived barriers to physical activity are potentially modifiable variables
which could be incorporated into interventions designed to improve physical
activity engagement. Future research should explore whether a measurement tool
tailored to capture beliefs about physical activity identified by people with MS
would better predict participation in physical activity.
