Note. CI = confidence interval. Substance Abuse and Mental Health Services Administration (SAMHSA) requires that any description of overall sample sizes based on the restricted-use data files has to be rounded to the nearest 100, which intends to minimize potential disclosure risk. Covariates in each of the 4 final multivariable models were age, gender, race/ethnicity, education, employment status, region, self-rated health, the number of emergency room visits, substance use disorders, severity of mental illness, perceived unmet need for mental health treatment, state variations (27 individual states and DC), and accessibility of mental health treatment per 10 000 county residents (the number of community mental health centers, the number of licensed psychologists, the number of office-based psychiatrists, and the number of psychiatric hospitals).
