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

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

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, peermanaged 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 cognitivebehavioral 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 1year follow-up was higher after selfhelp 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

2-year follow-up of same sample
• 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)

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.
