Objective To compare adults with different insurance coverage in care for alcohol, drug abuse, and mental health (ADM) problems.

Data Sources/Study Setting. From a national telephone survey of 9,585 respondents.

Design. Follow-up of adult participants in the Community Tracking Study.

Data Collection. Self-report survey of insurance plan (Medicare, Medicaid, unmanaged, fully, or partially managed private, or uninsured), ADM need, use of ADM services and treatments, and satisfaction with care in the last 12 months.

Principal Methods. Logistic and linear regressions were used to compare persons by insurance type in ADM use.

Principal Findings The likelihood of ADM care was highest under Medicaid and lowest for the uninsured and those under Medicare. Perceived unmet need was highest for the uninsured and lowest under Medicare. Persons in fully rather than partially managed private plans tend to be more likely to have ADM care and ADM treatments given need. Satisfaction with care was high in public plans and low for the uninsured.

Conclusions. The uninsured have the most problems with access to and quality of ADM care, relative to the somewhat comparable Medicaid population. Persons in fully managed plans had better rather than worse access and quality compared to partially managed plans, but findings are exploratory. Despite low ADM use, those with Medicare tend to be satisfied. Across plans, unmet need for ADM care was high, suggesting changes are needed in policy and practice.
