- Abstract
Background: With a growing population of older adults with multiple sclerosis (MS), appropriate strategies are needed to promote physical activity (PA) as a second-line approach for symptom management. Objectives: This cross-sectional study examined built environment, social environment, and individual social cognitive theory (SCT) variables as hierarchical correlates of PA in older adults with MS using a social ecological model (SEM) framework. Methods: 363 participants completed the online survey including demographics, the Abbreviated Neighborhood Walkability Scale (NEWS-A), Social Provisions Scale (SPS), Exercise Self-Efficacy Scale (EXSE), Multidimensional Outcome Expectations Scale for Exercise Scale (MOEES), and Godin Leisure-Time Exercise Questionnaire (GLTEQ) Total and Health Contribution score (HCS). Spearman rank-order correlation analyses were used to examine associations among NEWS-A subscales, SPS, EXSE, MOEES, and GLTEQ Total and HCS. We then conducted hierarchical, linear regression analysis whereby we regressed GLTEQ with NEWS-A subscales (built environment) in step 1, SPS (social environment) in step 2, then EXES and MOEES (individual determinants) in step 3. Results: Land-use mix diversity, land-use mix access, street connectivity, and aesthetics were significantly correlated with GLTEQ Total, whereas land-use mix diversity, land-use mix access, infrastructure and safety for walking, aesthetics, and crime were significantly correlated with GLTEQ HCS. Hierarchical linear regression analyses were then conducted whereby we regressed GLTEQ Total with NEWS-A subscales (step 1) with significant associations noted for landuse mix diversity and aesthetics (R2 = 0.09), step 2 included SPS with significant associations noted for SPS, land-use mix diversity, and aesthetics (R2 = 0.15), and finally EXSE and MOEES were included in step 3 and were the only significant correlates of GLTEQ total (R2 = 0.38). Regarding GLTEQ HCS, land-use mix diversity, aesthetics, and crime were significant correlates in step 1 (R2 = 0.10), SPS and land-use mix diversity were the only significant correlates in step 2 (R2 = 0.14), and EXSE was the only significant correlate in step 3 (R2 = 0.36). Conclusions: This study provides guidance for researchers and practitioners on relevant targets for tailoring PA interventions for older adults with MS and supports the continued emphasis on self-efficacy as a primary predictor of health behavior change and maintenance.
