title: The relationship of counseling and self-help participation to patient outcomes in DATOS.
abstract: Using a sample of 927 cocaine patients enrolled in programs in three modalities included in the national Drug Abuse Treatment Outcome Studies (DATOS), this investigation examined the relationship of three dimensions of treatment process on after-treatment cocaine and heavy alcohol use and predatory illegal activity. Logistic regression revealed significant reductions in all three outcomes and strong effects of treatment duration and after-treatment self-help, conditional on the modality. Results did not support the hypothesized relationship between treatment outcomes and amounts of counseling and during-treatment self-help. Findings support the robustness of duration effects and after-treatment self-help and contribute to the measurement methodology for calibrating treatment intensity. The strong after-treatment self-help effect in the two residential and inpatient modalities suggests these programs can improve treatment outcomes by making referral to after-treatment self-help participation a standard practice and installing mechanisms to increase the likelihood of attendance at least twice weekly during the year after treatment.
