  1. Notes. All χ2 significant at the <.001 level, NEWS-Y-IPEN = Neighborhood Environment Walkability Scale for Youth for the IPEN Adolescent study, df degrees of freedom, CFI comparative fit index, RMSEA root mean square error of approximation, SRMR standardized root mean squared residuals, 95% CI 95% confidence intervals. aNew Zealand collected NEWS-Y data from adolescents only. Thus, for New Zealand, confirmatory factor analyses were performed on adolescent data, while for the other countries they were performed using parents’ data
