Contingency Management
Core Mechanism
Immediate, tangible reinforcement for abstinence directly competes with drug reinforcement; shifts behavioral economics of use
Ontology
Substance use maintained by powerful reinforcement contingencies; behavior follows reinforcement
Therapeutic Voice
"For every clean urine sample, you get to draw from the prize bowl. Three in a row doubles your draw."
View of the Person
A behavioral organism whose substance use follows reinforcement contingencies that can be systematically shifted
Evidence
SAMHSA: endorsed and funded (2023). NICE: recommended
50+ RCTs
Multiple Cochrane reviews
Very strong evidence — arguably most effective for stimulant use.
Conditions
Epistemology
Blind Spots
Reinforcement effects may not persist after incentives end; ethical concerns about paying patients; limited to substance use
Contraindications
Active psychosis preventing comprehension of contingencies, situations where reinforcers could be harmful (e.g., money for someone with gambling disorder), environments without capacity to deliver consistent reinforcement, ethical concerns about withholding rewards from vulnerable populations
Training
Graduate behavioral principles training sufficient. Implementation requires institutional infrastructure
No formal certification
Graduate coursework + implementation 4-8 hrs
Minimal training; incentive budget costs
Philosophical Roots
Skinner (operant conditioning); Herrnstein (matching law); behavioral economics (Bickel — delay discounting); pragmatism (reinforcement works whether or not insight occurs)
