PAL2 Study

Peer Alternatives for Addiction 2 Study

A Research Study to Generate a Deep Understanding of the Benefits of Mutual-Help Groups for Recovery

What Will the Study Achieve?

    • Provide a deep understanding of when, for whom, and why mutual-help group participation is helpful.
    • Shed light on effective mutual-help group alternatives.
    • Help doctors and other clinicians make informed referrals to mutual-help alternatives, and alert courts and policymakers to effective resources in addiction treatment.
    • Help individuals to make the best choice possible among the range of effective peer support options.

“The PAL2 study represents the largest and most comprehensive study of mutual-help groups to date; it will greatly expand understanding of the benefits of this vital recovery support.”
