Abstract

The number and type of services offered at substance abuse treatment (SAT) facilities are important aspects of the quality of care. Managed care (MC) is a growing presence in SAT and has been shown to affect the provision of treatment. We expand on earlier work and examine the impact of managed care on the number and type of services offered by methadone maintenance (MM) and drug-free (DF) outpatient treatment facilities. We use the econometric technique of instrumental variables to address the issue of endogeneity of MC and service offerings, thereby allowing a causal interpretation of results. Using data from the 2000 National Survey of Substance Abuse Treatment Services, we find that MC significantly increases the total number of services offered in MM outpatient facilities by four, yet decreases the number by two in DF outpatient facilities. We also show how the impact on specific services differs by modality and provide explanations for our findings.
