OBJECTIVE: To determine the psychometric properties of the
3-factor Multidimensional Outcome Expectations for Exercise Scale in a sample of
ambulatory, symptom-free persons with multiple sclerosis (MS). DESIGN:
Cross-sectional validation study. SETTING: Midwestern university. PARTICIPANTS:
Community-dwelling adults (N=242) with an established definite diagnosis of MS,
as corroborated by the participant's neurologist, who were relapse free for the
last 30 days and ambulatory with minimal assistance. INTERVENTIONS: Not
applicable. MAIN OUTCOME MEASURES: Multidimensional Outcome Expectations for
Exercise Scale, physical activity, self-efficacy, and physical health status.
Confirmatory factor analyses using covariance modeling and correlational analyses
were used to establish factorial and construct validity. RESULTS: Analyses showed
excellent factorial validity for the hypothesized factor structure reflecting
physical, social, and self-evaluative outcome expectations. All 3 subscales were
internally consistent. Theoretically, relevant correlations between outcome
expectations and self-efficacy, physical activity, and physical health status
were all supported. CONCLUSIONS: The Multidimensional Outcome Expectations for
Exercise Scale appears to be a reliable and valid measure of outcome expectations
for exercise in this limited sample of community-dwelling adults with MS. Further
validation in clinical samples is warranted.
