Separate models were created for neighborhood factors, adjusted for neighborhood level concentrated poverty and age, race and ethnicity.

Collective efficacy was highly correlated with concentrated poverty; therefore we tested it without concentrated poverty in a separate model not shown (parameter estimate −0.26 (SE=0.18, p>.05).

Statistically significant differences (p<.05) are in bold. All models were adjusted for neighborhood and school level clustering using SAS 9.3, Proc Mixed. Ref=reference.
