Evidence-Based Treatment Community Reinforcement Approach (CRA) Robert J. Meyers, Ph.D. Jane Ellen Smith, Ph.D. University of New Mexico
Early CRA Studies Hunt & Azrin, 1973 Azrin, 1976 Azrin, Sisson, Meyers, & Godley, 1982
Hunt & Azrin 1973 • inpatient alcoholics • job finding counseling • behavioral/marital tx • social/leisure counseling • reinforcer access counseling • social club • home visits • [total 50 hrs per client]
inpatient alcoholics disulfiram w/compliance protocol problem prevention rehearsal buddy system early warning mood monitoring some group tx ~70% as aftercare home visits [Average 30 contact hrs] Azrin 1976: New & Improved CRA
43 outpatient alcoholics 3 groups: traditional tx only traditional tx + disulfiram compliance CRA only increased use of positive reinforcement sobriety sampling immed. disulfiram drink refusal training +/- functional analysis job club phone contacts [Average: 5 tx sessions] 1st CRA Outpatient Study (Azrin, Sisson, Meyers, & Godley, 1982)
Results of 1982 study 6 month follow-up Disulfiram only group % days abs = 74% CRA + % days abs = 97% Traditional group % day abs = 45%
CRA with Homeless Alcohol-Dependent Individuals PI: Jane Ellen Smith Co-PI: Robert J. Meyers Funded by: NIAAA
Primary Questions Addressed: • Is CRA > a day shelter’s standard program for treating drinking problems among homeless individuals? • What are the effects of the 2 treatments on the non-drinking variables (employment, housing)?
CRA Group Group Sessions • Problem-Solving • Communication Skills • Drink-Refusal • Independent Living Skills • Goal Setting/Community Meeting • Social Club • Disulfiram Compliance Individual Sessions • Job Finding • Case Management • Couples Therapy
Standard Treatment Group • Day Shelter Program • Project Share • Alcoholics Anonymous Meetings • 12-Step Counselor • Job Service Program • VA Benefits Advisor • Project CARE
Grant-Provided Housing • All participants were housed • Normal stay: 3 months • Extended stays: if job and $ saved • Random breathalyzer tests
Drinks Per Week By Condition --- Standard --- CRA Median SECs 2 Month 4 Mont 6 Month 9 Month 12 Month Follow-Up Period
Percent Homeless By Condition CRA Standard Percent 2 Month 4 Month 6 Month 9 Month 12 Month Follow-up Periods
Percent Employed By Condition CRA Standard Percent Intake 2 Month 4 Month 6 Month 9 Month 12 Month Follow-up Period
Limitations of the Study • Not comparable “doses” of treatment • Some CRA participants still drinking heavily • Only moderate improvement in employment • Cost of housing
CRA with Homeless Alcoholic Women • Why women only? • Treatments: • Case Management • CRA • CRA + contingency-managed computer training

CRA for Illicit Drugs: Adult Studies Cocaine Higgins et al. (1991; 1993; 1994; 1995; 2000) Heroin Bickel et al. (1997) Abbott et al. (1998)
Godley et al. (2002) • Continuing care study (after residential treatment) • UCC (usual continuing care) or ACRA + case mgmt • 114 adolescents • 90% = marijuana dependent at intake • 57% = alcohol dependent • 82% = involved w/ juvenile justice system
Results: 3 months ACRA significantly > UCC in terms of: • abstinence from marijuana • reduced alcohol use
Cannabis Youth Treatment (CYT) Study (Dennis et al., 2004) • Outpatient treatment for marijuana • Trial 1:MET/CBT5; MET/CBT12; FSN • Trial 2: MET/CBT5; ACRA; MDFT • 600 adolescents • Hi rate of illegal activities
Results: 12 months Measures: (1) days of abstinence (from drugs & alcohol) (2) “in recovery” = living in community (not jail) + no use + no past month substance problems General Findings: All treatments significantly improved pre-post; no significant tx comparison differences
Best overall “in recovery” rates = ACRA (34%; next best = MET/CBT5 at 27%) • Best # of abstinent days for Trial 2 = ACRA (73% of days during the year; best for Trial 1= MET/CBT5 at 74%) • Most cost-effective? ACRA
Percent days of substance use Significant interaction between time (pre to 6 months) and group using number of treatment sessions as covariate (F (1, 81) = 9.10, p < .01).
Percentage of days off the street Trend toward interaction between time (pre to 6 months) and group using number of treatment sessions as covariate (F (1, 81) = 3.09, p =. 08).
What does not work! • Educational films and lectures • General alcoholism counseling • Psychotherapy • Confrontational counseling • Antipsychotic medication • Psychotherapy, group process • Insight therapy
Why Isn’t CRA Used More? • Disease Model • Limited accessibility • It’s hard to teach an old dog new tricks • “We already do that” • CRA isn’t “sexy”
