Maximizing the Efficacy of Cognitive Behavior Therapy and Contingency Management

Completed · Phase 2

Conditions studied: Marijuana Dependence

In brief

Cognitive-behavioral coping skills therapy (CBT) is a widely used and recognized treatment that has been empirically validated for a range of substance use disorders, often with emergent effects and continuing improvement even after treatment ends. Treatment retention and compliance are associated with enhanced treatment outcomes in CBT. Contingency management (CM) also has very strong support and is associated with rapid, robust effects on targeted outcomes. Despite their many strengths, neither CBT nor CM is universally effective. It is now essential to seek strategies to maximize and extend the effectiveness of these two approaches and to better understand how these treatments exert their effects.
