Notes. Results from separate multilevel models testing the effect of various housing characteristics on substance use, criminal justice, and employment outcomes parameterize clustering of observations within participants and participants within houses (ICCs ranging from 0.008–0.137). All random intercept models control for time, condition, their interaction, gender, race/ethnicity, age, educational attainment, and number of days in the house. Individual ORs, SEs, and p-values are listed for each category of categorical variables as well as the p-value for Wald test of the overall effect of the categorical variable.

*

Denotes models with missing data on house characteristics that were subjected to sensitivity analyses employing different multiple imputation techniques. Findings in bold typeface reflect those that were robust across these different techniques.

Reflects findings that remained statistically significant in multivariable multilevel models.
