Contingency management (CM) is the application of the three-term contingency (or operant conditioning), which uses stimulus control and consequences to change behavior. CM originally derived from the science of applied behavior analysis (ABA), but it is sometimes implemented from a cognitive-behavioral therapy (CBT) framework as well.
Incentive-based contingency management is well-established when used as a clinical behavior analysis (CBA) treatment for substance use disorders, which entails that patients earn money (vouchers) or other incentives (i.e., prizes) as a reward to reinforce drug abstinence (and, less often, punishment if they fail to adhere to program rules and regulations or their treatment plan). Another popular approach based on CM for alcoholism is the community reinforcement approach and family training (CRAFT) model, which uses self-management and shaping techniques.
By most evaluations, its procedures produce one of the largest effect sizes out of all mental health and educational interventions.{{Cite journal |last1=Forness |first1=Steven R. |last2=Kavale |first2=Kenneth A. |last3=Blum |first3=Ilaina M. |last4=Lloyd |first4=John W. |date=1997 |title=Mega-Analysis of Meta-Analyses |url=http://dx.doi.org/10.1177/004005999702900601 |journal=TEACHING Exceptional Children |volume=29 |issue=6 |pages=4–9 |doi=10.1177/004005999702900601 |s2cid=148914363 |issn=0040-0599|url-access=subscription }}
Token economies
One form of contingency management is the token economy system.Zlomke, L. (2003). Token Economies. The Behavior Analyst Today, 4 (2), 177–184 [http://www.baojournal.com BAO] Token systems can be used in an individual or group format.{{Cite journal |last=Axelrod |first=Saul |date=1973 |title=Comparison of individual and group contingencies in two special classes |url=http://dx.doi.org/10.1016/s0005-7894(73)80076-0 |journal=Behavior Therapy |volume=4 |issue=1 |pages=83–90 |doi=10.1016/s0005-7894(73)80076-0 |issn=0005-7894|url-access=subscription }} Token systems are successful with a diverse array of populations including those suffering from addiction,Petry, N.M.

JEIBI, 1 (1), 95–99 [http://www.baojournal.com BAO] The exception to the last would be the treatment of stuttering.Ryan, B.P. (2004) Contingency Management and Stuttering in Children, The Behavior Analyst Today, 5 (2), 144–169 [http://www.baojournal.com BAO] The goal of such systems is to gradually thin out and to help the person begin to access the natural community of reinforcement (the reinforcement typically received in the world for performing the behavior).Baer, D.M., & Wolf, M.M. (1970). "The entry into natural communities of reinforcement". In R. Ulrich, T. Stachnik, & J. Mabry (Eds.), Control of human behavior: Volume II. Glenview, Ill.: Scott, Foresman.
Walker (1990) presents an overview of token systems and combining such procedures with other interventions in the classroom.Walker, H. (1990). The Acting Out Child. Soporis West. He relates the comprehensiveness of token systems to the child's level of difficulty.

A meta-analysis of contingency management in drug programs showed that it has a large effect.{{Cite journal |last1=Schumacher |first1=Joseph E. |last2=Milby |first2=Jesse B. |last3=Wallace |first3=Dennis |last4=Meehan |first4=Dawna-Cricket |last5=Kertesz |first5=Stefan |last6=Vuchinich |first6=Rudy |last7=Dunning |first7=Jonathan |last8=Usdan |first8=Stuart |date=2007 |title=Meta-analysis of day treatment and contingency-management dismantling research: Birmingham Homeless Cocaine Studies (1990-2006). |url=http://doi.apa.org/getdoi.cfm?doi=10.1037/0022-006X.75.5.823 |journal=Journal of Consulting and Clinical Psychology |language=en |volume=75 |issue=5 |pages=823–828 |doi=10.1037/0022-006X.75.5.823 |pmid=17907865 |issn=1939-2117|url-access=subscription }} These contingencies are delivered based on abstinence and attendance goalsStitzer ML, Petry N, Peirce J, Kirby K, Killeen T, Roll J, Hamilton J, Stabile PQ, Sterling R, Brown C, Kolodner K, Li R.

In contrast to these findings in a recent study, the researchers found out that nicotine replacement treatment only improved the effects of contingent vouchers on short-term smoking abstinence. However, in the long term, the effects of contingent vouchers had no impact on tobacco resistance.
Level systems
Level systems are often employed as a form of contingency management system. Level systems are designed such that once one level is achieved, then the person earns all the privileges for that level and the levels lower than it.Cancio, E. & Johnson, J.W. (2007). Level Systems Revisited: An Impact Tool For Educating Students with Emotional and Behavioral Disorders. International Journal of Behavioral Consultation and Therapy, 3 (4), 512–527.

Organizations
Many organizations exist for board certified behavior analysts using contingency management programs around the world.
