Impact of state and trait anxiety severity on retention and phase advancement in an outpatient buprenorphine treatment program.

Background And Objectives: Comorbid anxiety is common among buprenorphine patients and may lead to poorer outcomes.

Methods: A retrospective chart review of 94 patients admitted to an outpatient buprenorphine treatment program was conducted.
