Electrophysiological Predictors and Indicators of Contingency Management Treatment Response

VA Office of Research and Development·interventional·Posted Jan 10, 2019·Updated Sep 30, 2025

In Brief

A clinical study evaluating Prize-Based Contingency Management and Treatment As Usual Outpatient Substance Use Treatment for Cocaine Use Disorder. Completed, enrolled 63 participants across 1 site.

Detailed Summary

The proposed work will investigate changes in brain signaling and cognitive functioning that support recovery from addiction, as well as use of pretreatment neurocognitive functioning to inform substance use treatment planning. Substance use disorders are prevalent amongst Veterans. Cocaine addiction, in particular, has been shown to complicate treatment of other high priority behavioral health problems in the Veteran population (e.g., PTSD, opioid addiction). While there are currently no approved medications to support recovery from cocaine addiction, research indicates that Contingency Management (CM) - a behavioral intervention for cocaine users - can be effective. However, individual responses are variable and long-term benefits are limited. This CDA will test a new model of how CM works by examining brain-based predictors and indicators of treatment response. Results will have immediate implications for measurement-based implementation of existing CM variants within the VA, supporting access to the version of CM that is best aligned with each Veteran's needs.

Interventions

Prize-Based Contingency Managementbehavioral

Participants assigned to Prize-based Contingency Management (PBCM) conditions will receive PBCM as an adjunct to TAU. PBCM will involve twice weekly one-on-one sessions with a provider for 12-weeks. During each session, a urine specimen provided by the patient will be tested for cocaine using a point-of-care dip-test. Results of point-of-care testing will be shared with the patient and negative results will be reinforced with draws from a fish bowl containing 500 paper slips, 250 of which award small, large, or jumbo prizes (remaining slips deliver words of encouragement). Patients will be reinforced with a single prize draw for their first negative specimen; an additional prize draw will be added for each consecutive negative result (up to 8 prize draws per session). Abstinence-contingent prize draws will be reset to one upon either a positive test result or unexcused, missed appointment.

Treatment As Usual Outpatient Substance Use Treatmentbehavioral

All participants will receive treatment as usual outpatient substance use services during the 12-week treatment interval. TAU will specifically entail recommended participation in at least two outpatient group and/or individual psychotherapy encounters per week within the Center for Treatment of Addictive Disorders (CTAD) at VA Pittsburgh Healthcare System. Participants will additionally continue any previously prescribed pharmacotherapy for substance use and/or other mental health conditions, if applicable.
