The Community Health Inclusion Index (CHII) is a new instrument developed to provide communities with the ability to measure how well they support healthy, active living for persons with disabilities.  The purpose of this study is to establish the convergent validity among a subset of constructs within the CHII related to pedestrian and transportation infrastructure.

Convergent validity was measured between each construct and measures of a community’s median income, level of urbanity, and percentage of the population with a disability. Data was analyzed from field testing of the CHII in 154 sites within 15 geographically diverse communities.  Constructs previously shown to have good internal consistency (Cronbach’s alpha>.70) were scored as percent correct. Pearson’s r and Spearman’s rho were used to establish relationships.  Subsequent OLS regressions modeled each construct with the 3 community variables and were run clustering standard errors by communities as a sensitivity analysis. 

Income was negatively correlated with transit accessibility(r= -.36, p<.01), and positively correlated with appealing walking features(r=.56, p<.0001), intersections(r=.28, p<.05) and paths(r=.24, p<.01).  Being in a rural community was negatively correlated with intersections(ρ=-.30, p<.01), transit(ρ=-.29, p<.05) and appealing walking features(ρ=-.23, p<.01).  Percentage of the population with a disability was correlated with transit accessibility(r=.34, p<.01), appealing walking(r=-.35, p<.0001) and parking(r=-.39, p<.0001).  After controlling for clustering, most of the significant relationships held.

The CHII showed moderate levels of convergent validity, and it can be used to assess the transit and pedestrian infrastructure around health promoting sites to determine level of access for persons with disabilities.
