title: Type of health insurance and the substance abuse treatment gap.
abstract: OBJECTIVE
  Most individuals reporting symptoms consistent with substance use disorders do not receive care. This study examines the correlation between type of insurance coverage and receipt of substance abuse treatment, controlling for other observable factors that may influence treatment receipt.
  
  
  METHODS
  Descriptive and multivariate analyses are conducted using pooled observations from the 2002-2007 editions of the National Survey on Drug Use and Health. The likelihood of treatment entry is estimated by type of insurance coverage controlling for personal characteristics and characteristics of the individual's substance use disorder.
  
  
  RESULTS
  Multivariate analyses that control for type of substance and severity of disorder (dependence vs. abuse) find that those with Civilian Health and Medical Program of the Uniformed Services/Veterans Affairs, Medicaid only, Medicare only, and Medicare and Medicaid (dual eligibles) have 50% to almost 90% greater odds of receiving treatment relative to those with private insurance.
  
  
  CONCLUSIONS
  The privately insured population has substantially lower treatment entry rates than those with publicly provided insurance. Additional research is warranted to understand the source of the differences across insurance types so that improvements can be achieved.
