1 The Evidence Base on Peer- Managed Addiction Recovery Organisations Professor Keith Humphreys Veterans Affairs and Stanford University Medical Centers, Palo Alto, California And Institute of Psychiatry and National Addiction Centre, Kings College London Presented 8 June 2012 at NTA Conference, Birmingham, UK

2 Overview Definition and Scope of peer-led recovery organisations Effectiveness and Cost-effectiveness of 12-step based organisations Clinical and Policy implications

3 Definition of Self-Help (aka Mutual Help) Recovery Organisations 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

4 Addiction self-help organizations are an international phenomenon Austria: Blue Cross France: Vie Libre Hong Kong: SAARDA Japan: Danshukai Poland: Abstainers Clubs Sweden: The Links Iran: Narcotics Anonymous

5 Note: NA is for all drugs not just narcotics 12-step groups have established themselves in the once-impenetrable Middle East

8 But do they work? Popularity does not equal effectiveness Most forms of recovery-oriented intervention have not been well-evaluated However, a sizable evidence base has accumulated regarding 12-step oriented interventions

9 Selected data on clinical and cost-effectiveness* *Summarizing the data where they are at present

10 Clinical trial of Oxford House Oxford House is a democratic, self- supporting, peer-managed residential setting 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

11 At 24-months, Oxford House (OH) produced 1.5 to 2 times better outcomes Jason et al. (2006). Communal housing settings enhance substance abuse recovery. American J Public Health, 96, 1727-1729.

12 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 Source: Timko, C. (2006). Intensive referral to 12-step self-help groups and 6-month substance use disorder outcomes. Addiction, 101, 678-688.

13 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.

14 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 with abstinent friends Source: see Humphreys, K.

15 Studies of cost consequences

16 Incorporating mutual-help principles in to treatment increases cost-effectiveness Sample:249 low-income alcohol-dependent patients Design:Random assignment to usual care or experimental unit with 50% less staff and higher expectation of patient self and mutual help Results: One-year outcomes comparable except for better social adjustment among experimental patients Source: Galanter, M. et al. (1987). Institutional self-help therapy for alcoholism: Clinical outcome. Alcoholism: Clinical & Experimental Resesarch, 11, 424-429.

17 Total alcohol-related health care costs over three years by comparable alcoholic individuals who initially chose Alcoholics Anonymous or professional outpatient treatment AA groupOutpatient group (n=135)(n=66)F meanmean (df=1,199) Per person costs Year 1 £1,100 £ 3,100 Years 2 and 3 £1,100 £ 1,000 Total £2,200 £ 4,100 5.52* Note *p<.05 Humphreys, K., & Moos, R.

19 Replication of cost offset findings in Department of Veterans Affairs Sample Source: This study appeared in Alcoholism: Clinical and Experimental Research, 25, 711-716.

20 Design 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

21 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

22 1-Year Clinical Outcomes (%) Note: Abstinence higher in 12-step, p<.001

27 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% Source:Sisson, P.W., & Mallams, J.H.

31 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. Other recovery mutual help organisations should be more greatly studied. Applying these findings in treatment settings should improve outcomes and reduce costs. A modest investment in self-help supportive infrastructure would likely more than pay for itself and yield significant public health gains.
