^aNonresponse weighting was used to address missing data for 18% of patients in the intent-to-treat sample who did not complete the six-month assessment. Mean scores are standardized predictions (also known as predictive margins) generated from the fitted regression models. Analysis of covariance models were fitted for continuous outcomes (measures shown); independent variables included intervention status, racial-ethnic group, and their interactions, with adjustment for baseline scores on each measure and study site. Two-step modeling was used by first fitting random intercept models for sites and then including the estimated random effects for sites in the final analysis of covariance model.

^cPossible scores on the Center for Epidemiological Studies Depression Scale (CES-D) range from 0 to 60, with scores above 24 indicating severe depression. The CES-D was not included in the baseline assessment; however, scores on the CES-D and the Mental Health Index–5 (MHI-5) were highly correlated (r=.78), and the baseline MHI-5 score was used as the proxy for baseline CES-D.

^dPossible scores range from 0 to 100, with higher scores indicating greater quality of life.

^eBased on two items assessing satisfaction. Possible scores range from 0 to 10, with scores higher score indicating greater satisfaction.
