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.
