Drug User’s Dilemma
Easy money
Hang with friends
Get high
Get a job
Time with family
Better health
Motivational Incentives Can
Counteract Ambivalence
Make sober living a more
attractive option through
positive reinforcement of
abstinence and other
behavior change
People Respond to Consequences
• Behavior can be changed by consequences
– Rewards increase desired behavior
– Punishment and sanctions decrease undesired
behavior
Contingency Management:
Application in Drug Abuse
• Measurable target behavior
• Rewarding consequence
Application in Drug Abuse
Treatment: Early Studies
• Behavioral targets:
– Counseling attendance
– Drug use during treatment
– On-time fee payment
• Reinforcing consequences:
– Money (or vouchers)
– Privileges (e.g. methadone take-home doses)
Incentive Effects on
Benzodiazepine Use
3-month intervention with methadone maintained
benzo users; incentive is take-home or money
Percent benzo negative urines
– Before incentives
– During incentives
– After incentives

Voucher Reinforcement
making cocaine abstinence a more
attractive option
• Intensive counseling plus
• Points earned for cocaine negative
urine results
– Escalating schedule with reset penalty
– Trade in points for goods
– $1000 available in first 3 months

Voucher Reinforcement
• Elegantly incorporates behavioral principles
designed to initiate & sustain abstinence
• Demonstrated efficacy in controlled trials
BUT
• Sample sizes are small
• Costs were high ($1000 per client could be earned)
$1000???
You’ve got to be
kidding!!!

For cost reduction in community clinic settings
Fishbowl Method
Incentive = draws from a bowl
- Draws earned for each negative urine or BAC
- Number of draws can escalate
- Bonus draws can be given for
consecutive weeks of abstinence
Half the slips are winners
Win frequency inversely related to cost
 largest chance of winning a
small $1 prize
 moderate chance of winning
a large $20 prize
 small chance of winning a
jumbo $100 prize

CTN Mission
• Conduct effectiveness research with
community treatment partners
– Do interventions developed and studied in research
clinics work when tested in the real world settings?
– If so, how can we make these new treatments part
of usual care?
How do abstinence incentives fit into the
clinical picture?
• Add-on to counseling as usual
– Special intervention to enhance motivation for
sustained abstinence
– Focuses on the positive to recognize and celebrate
success
– Allows counselors to work on life-style changes
that can sustain abstinence beyond incentives
CTN MIEDAR Study
Participants = 800 stimulant users
(cocaine or methamphetamine)
Conducted in:
6 methadone and
8 drug-free programs
Random Assignment
• Usual care
• Usual care enhanced with
abstinence incentives
• 3-month evaluation

Psychosocial Site Differences:
Raising Performance
• Abstinence incentives worked best in clinics
with lower retention
– Control mean = 3.6 - 6.8 weeks
• Clinics where clients were usually retained for
8 weeks didn’t show improved retention with
incentives
Individual Subject Performance
19% incentive vs 5% control
had 12 weeks of
stimulant negative samples
RESEARCH CONCLUSIONS
Incentives can improve client
outcomes on retention and
drug use when implemented
in community treatment
programs
Dissemination/Adoption
• Clearly recognized as one evidence-based practice
advocated by program funders and licensers
• 1/4 - 1/3 of clinics are currently using incentivesmostly to reinforce attendance (Roman et al., 2010)
• Information on what it is and how to do it
increasingly available
– e.g. PAMI materials at www.nattc.org
– programs such as this one today

Why Adopt Motivational Incentives?
from Kellogg et al., Something of Value, JSAT, 2005
Counselors Come to Understand
Reinforcement
• “We came to see that we need to reward people
where rewards in their lives were few and far
between
• We use the rewards as a clinical tool – not as
bribery, but for recognition
• The really profound rewards will come later”
49
Clients Like it
• “Clients are proud and are having fun
• Early in treatment, when their name is called out,
they are feeling good that they are being
acknowledged
• For once in their life, they are being rewarded for
something”
50
Contributes to Positive
Clinician-Client Interaction
• When patients publicly, and sometimes
tearfully, acknowledged the counselor’s help
in public, the staff felt a sense of gratitude
• “In the last two award ceremonies, clients said,
‘I want to thank the staff….’ That sounded
real good – we felt appreciated”
