Cross-validation of the factorial structure of the Neighborhood Environment Walkability Scale (NEWS) and its abbreviated form (NEWS-A)

Table 5 Correlations between blockgroup-level latent factors of the NEWS (above the diagonal) and NEWS-A (below the diagonal).

NEWS-A factors		BL2	BL3	BL4	BL5	BL6	NEWS factors
Land use mix – access and infrastructure for walking (BL1_A)		-.29	.66	< .10^a	-.51	.19	Land use mix – access and infrastructure for walking (BL1)
Physical obstacles to walking (BL2_A)	-.54		< .10^a	< .10^a	< .10^a	- .14	Physical obstacles to walking (BL2)
Green areas (BL3_A)	< .10^a	< .10^a		.41	-.46	.26	Sidewalks (BL3)
Aesthetics and safety from crime (BL4_A)	-.46	< .10^a	.47		.42	.36	Green areas (BL4)
Traffic safety and presence of people (BL5_A)	.52	-.45	.57	.18		.39	Aesthetics and safety from crime (BL5)
	BL1_A	BL2_A	BL3_A	BL4_A			Traffic safety and presence of people (BL6)

^a constrained to zero in the final model as correlation coefficients smaller than |.10|. The subscript A stands for NEWS-A.
