Contingency management

For use in management theory, see Contingency theory.

Contingency management (CM) is a type of clinical behavior analysis therapy which is most-widely used in the field of substance abuse. CM refers to the application of the three-term contingency of operant conditioning, using stimulus control and consequences to alter behavior. Patients' behaviors are rewarded (or, less often, punished); generally, adherence to or failure to adhere to program rules and regulations or their treatment plan. CM derives from the science of applied behavior analysis (ABA), and by most evaluations, its procedures produces one of the largest effect sizes out of all mental health and educational interventions.[1]

Token economies

One form of contingency management is the token economy system.[2] Token systems can be used in an individual or group format.[3] Token systems have been shown to be successful with a diverse array of populations including those suffering from addiction,[4] those with special needs,[5] and delinquents.[6] However, recent research questions the use of token systems with very young children.[7] The exception to the last would be the treatment of stuttering.[8] 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).[9]

Walker (1990) presents an overview of token systems and combining such procedures with other interventions in the classroom.[10] He relates the comprehensiveness of token systems to the child's level of difficulty.

Voucher programs and related applications in addiction treatment

Another form of contingency management is voucher programs. In voucher-based contingency management patients earn vouchers exchangeable for retail items contingent upon objectively verified abstinence from recent drug use or compliance with other behavior-change targets. This particular form of contingency management was introduced in the early 1990s as a treatment for cocaine dependence.[11][12] The approach is the most reliably effective method for producing cocaine abstinence in controlled clinical trials.[13][14]

Medication take-home privileges is another form of contingency management frequently used in methadone maintenance treatment. Patients are permitted to "earn" take-home doses of their methadone in exchange for increasing, decreasing, or ceasing certain behaviors. For example, a patient may be given one take-home dose per week after submitting negative drug screens (generally via urine testing) for three months. (It is worth noting that take home-doses (or "bottles") are seen as desirable rewards because they allow patients to come to the clinic less often to obtain their medication).

Based in applied behavior analysis (ABA), contingency management includes techniques such as choice, shaping, time-out, making contracts between the therapist and patient, and token economy.

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.[15]

Effectiveness in addiction programs

A recent meta-analysis of contingency management in drug programs showed that it has a large effect.[16] These contingencies are delivered based on abstinence and attendance goals[17][18] and can take the form of vouchers, the opportunity to win prizes, or privileges. They have been used with single problem addictions as well as dual diagnoses[19][20] and homeless.[21] Overall contingency management has been found to be an effective and cost efficient addition to drug treatment.[22]

Organizations

Many organizations exists for board certified behavior analysts using contingency management around the world.
