a

Twelve-month service use within a particular treatment sector was defined as making at least one visit to a member of the treatment sector within the 12 months prior to the respondent’s interview for problems with their emotions, nerves, mental health, or use of alcohol or drugs.

b

Sample size=779, as 51 African American respondents 55 years and older did not answer the WHO-CIDI items in the questionnaire, and an additional 7 cases had missing values on at least one of the covariates.

c

The p-value is based on the design-corrected Wald chi-square test with 1 degree of freedom.

d

The p-value is based on the design-corrected Wald chi-square test with 2 degrees of freedom.
