The purpose of the study is to conduct a follow-up of substance abuse patients (n=1,269) about 2 to 5 years since they were originally recruited from 8 substance abuse treatment clinics (located in 5 states) to participate in a prior clinical trial study called "START" (Starting Treatment with Agonist Replacement Therapies). The START Follow-up Study will be conducted over 5 years and will involve three follow-up interviews with START participants.

The specific aims of the START Follow-up Study are as follows.

  1. To determine longer-term outcomes of Suboxone versus methadone treatment received in the START
  2. To investigate patient and treatment factors associated with post-START treatment access, utilization, and outcomes among Suboxone and methadone patients
  3. To explore other correlates of the long-term outcomes among START patients.
