Overview •  Definition and Scope of mutual help

organizations •  Effectiveness and Cost-effectiveness of

12-step based groups •  Clinical and Policy implications

Definition of Self-Help (aka Mutual Help) Organizations

Essential •  Peer-directed, self-governing •  Value experiential knowledge and reciprocal helping •  Free or nominal cost only Some •  Provide a structured “program” and philosophy •  Have an abstinence orientation •  Attendance by addicted person/Attendance alone •  Spiritual or Religious Content •  Have a Residential Structure

Addiction self-help organizations are an international phenomenon

•  Austria: Blue Cross •  France: Vie Libre •  Hong Kong: SAARDA •  Japan: Danshukai •  Poland: Abstainer’s Clubs •  Sweden: The Links •  Iran: Narcotics Anonymous

But do they work?

•  Popularity does not equal effectiveness •  However, a sizable evidence base has

accumulated regarding 12-step oriented interventions

Background on AA, the prototypic 12-step organization

•  Founded in Akron, Ohio in 1934 •  Sole purpose: To help alcoholics become sober •  Explosive growth in U.S. and world •  Non-diverse to start, now wildly so •  4-6 million members worldwide •  Spawned many spinoffs and also influence

professionals substantially

Veterans Affairs RCT on AA/NA referral for outpatients

•  345 VA outpatients randomized to standard or intensive 12-step group referral

•  81.4% FU at 6 months •  Higher rates of 12-step involvement in

intensive condition •  Over 60% greater improvement in ASI

alcohol and drug composite scores in intensive referral condition

Changing network support for drinking trial (n= 210)

•  Patients Randomized to Case Management

or Network Support Approaches

•  At 15 months, network approaches had higher AA involvement, 20% more abstaining days

Mark D. Litt, Ronald M. Kadden, Elise Kabela-Cormier, and Nancy Petry (2007). Changing Network Support for Drinking: Initial Findings From the Network Support Project. Journal of Consulting and Clinical Psychology, 71, 118-128.

Integration of federally funded 12-step facilitation trials

•  Instrumental variables analysis of over 2,300 patients in six trials

•  Used randomization as instrument to test impact of AA free of selection bias

•  AA effective in 5 of 6 trials •  Alcoholism Clinical and Experimental

Research, 38 (on line early)

Clinical trial of Oxford House

•  Oxford House is a 12-step influenced, peer-managed residential setting in which almost all patients attend AA/NA

•  150 Patients randomized after inpatient treatment to Oxford House or TAU

•  77% African American; 62% Female •  Follow-ups every 6 months for 2 years, 90%

of subjects re-contacted

At 24-months, Oxford House (OH) produced 1.5 to 2 times better outcomes

Replication of cost offset findings in Department of Veterans Affairs Sample

Source: This study appeared in Alcoholism: Clinical and Experimental Research, 25, 711-716.

Quasi-Experimental Design, I

•  Follow-up study of over 1700 VA patients (100% male, 46% African-American) receiving one of two types of care:

•  5 programs were based on 12-step principles and placed heavy emphasis on self-help activities

•  5 programs were based on cognitive-behavioral principles and placed little emphasis on self-help activities

Quasi-Experimental Design, II

•  Nearest programs hundreds of miles apart •  Patients matched on prior mental health/

SUD care utilization •  No baseline differences in marriage,

employment, comorbid psychiatric disorder, current substance use, service utilization or self-help group involvement

•  100% follow-up on utilization outcomes, 84% on other outcomes

Self-help group participation at 1-year follow-up was higher after self-help oriented treatment

•  36% of 12-step program patients had a sponsor, over double the rate of cognitive-behavioral program patients

•  60% of 12-step program patients were attending

self-help groups, compared with slightly less than half of cognitive-behavioral program patients

•  50% to 100% higher self-help group involvement measures favoring 12-step

•  Abstinence difference increased: 49.5% in

12-step versus 37.0% in CB •  A further $2,440 health care cost reduction

(total for two years = $8,175 in 2006USD)

Motivation to change

Partial mediators of 12-step groups’ effect on substance use identified in research

•  Increased self-efficacy •  Strengthened commitment to abstinence •  More active coping •  Enhanced social support •  Greater spiritual and altruistic behavior •  Replacement of substance-using friends

Clinical and Policy Implications

Intreatment preparation for AA produces better outcomes

•  ON/OFF design with 508 patients •  Experimental received “Making Alcoholics

Anonymous Easier” (MAAEZ) training •  At 12 months, 1.85 higher odds for alcohol

abstinence, 2.21 for drug abstinence for those receiving MAAEZ

Source: Kaskutas, L.A., et al. (2009). Journal of Substance Abuse Treatment, 37, 228-239.

“We do that already: Normal referral processes are ineffective

Sample: 20 alcohol outpatients

Design: Outpatients randomly assigned to standard 12-step self-help group referral (list of meetings and therapist encouragement to attend) or intensive referral (in-session phone call to active 12-step group member)

Results: Attendance rate after intensive referral: 100% Attendance rate after standard referral: 0%

UK SMART expansion project

•  Partnership between DoH, Alcohol Concern and SMART Recovery UK

•  Developed training, local champions, referral processes in 6 sites in England

•  Established 18 groups in 4 regions (12 original, 6 spinoffs)

•  Raised profile of SMART with professionals and public

Conclusions •  12-step group participation significantly

reduces substance use and health care costs. •  Benefits of 12-step groups mediated both by

psychological and social changes. •  Applying these findings in treatment settings

should improve outcomes and reduce costs. •  Investment in self-help supportive

infrastructure may benefit public. •  Recovery movement has political potential.
