Which combination is commonly used as an evidence-based practice for substance use disorders?

• A. Only pharmacotherapy.
• B. Motivational Interviewing, CBT-based relapse prevention, and contingency management.
• C. Psychoanalysis and dream interpretation.
• D. Unstructured therapy alone.

Answer: (B)

A well-supported approach to substance use disorders combines motivational interviewing, CBT-based relapse prevention, and contingency management. Motivational Interviewing helps clients resolve ambivalence and build willingness to change, setting the stage for engage in treatment. CBT-based relapse prevention teaches concrete skills to recognize triggers, manage cravings, and develop coping strategies to handle high-risk situations, which reduces the chance of slipping back into use. Contingency management adds tangible rewards to reinforce abstinence or adherence to treatment, leveraging behavioral principles that have shown strong evidence across various substances. When used together, these approaches create a structured, evidence-backed framework that many clinicians use in practice. Other options fall short: pharmacotherapy alone lacks the psychosocial components that improve long-term outcomes; psychoanalysis and dream interpretation do not have solid evidence for treating substance use disorders; and unstructured therapy lacks the formal, evidence-based methods that drive effectiveness.
