Abbreviated Neighborhood Environment Walkability scale in persons with multiple sclerosis: Initial validation of score inferences

Abstract

IntroductionThere is increasing interest in perceptions of the built environment as a correlate of physical activity among persons with multiple sclerosis (MS). This study examined if scores from the Abbreviated Neighborhood Environment Walkability Scale (NEWS-A) provide a valid inference regarding features of the environment in MS. MethodsParticipants completed a cross-sectional survey that included the NEWS-A as well as a demographic and clinical characteristics measure and the Social Provisions Scale (SPS). Walk Scores® were calculated based on residential addresses. We examined Spearman's Rank-Order Correlations (rs) among NEWS-A subscales with Walk Scores®, social environment, and individual factors, and interpreted the correlations based on a nomological network informed by a social-ecological model. ResultsThere were complete data for 566 participants with MS. There were large correlations between NEWS-A land-use mix diversity, land-use mix access, infrastructure for safety and walking with Walk Scores® (rs = 0.51–0.57). There were medium correlations between NEWS-A residential density, street connectivity, and crime with Walk Scores® (rs = 0.31–0.48), and small correlations between NEWS-A aesthetics and traffic hazards with Walk Scores® (rs = 0.04–0.10). There were small-medium correlations between all other NEWS-A subscales with SPS, marital status, age, and PDDS (rs = 0.01–0.39). ConclusionsOur results provide initial evidence for the validity of NEWS-A scores as a measure of perceived neighborhood walkability that may be associated with health behaviors in MS.
