Selection Bias Free Estimation of the Impact of Drug-focused Twelve Step Mutual Help Groups Using the VA Database (NIH HEAL Initiative)

Funded by the NIH HEAL Initiative

Using a meta-analytic approach retrospectively analyzing data of individuals with drug use disorders, determine the impact of drug-focused 12-step mutual help groups, free of selection bias, in reducing opioid consumption and opioid-related problems.  These data will be used to generate hypotheses on how the augmentation of 12-step mutual help groups, added to medication-assisted treatments (MAT), may be used to improve retention in treatment.
