Validity of the Multidimensional Outcome Expectations for Exercise Scale in Continuing-Care Retirement Communities
Objective: The current study examined the psychometric properties and validity of the Multidimensional Outcome Expectations for Exercise Scale (MOEES) in a sample of older adults with physical and functional comorbidities. Methods: Confirmatory factor analysis was used to examine the hypothesized 3-factor model in 108 older adults (M age 85 yr) residing in continuing-care retirement communities. Results: Analyses supported the 3-factor structure of the MOEES reflecting physical, social, and self-evaluative outcome expectations, with a 12-item model providing the best fit.
Theorized bivariate associations between outcome expectations and physical activity, self-efficacy, and functional performance were all supported. Conclusions: The 12-item version of the MOEES appears to be a reliable and valid measure of outcome expectations for exercise in this sample of older adults with physical and functional comorbidities. Further examination of the factor structure and the longitudinal properties of this measure in older adults is warranted.
