Which practices constitute evidence-based approaches for treating substance use disorders?

• A. Purely motivational interviewing only.
• B. Psychoanalysis and client-centered therapy.
• C. Medication-only pharmacotherapy with no counseling.
• D. Motivational Interviewing and CBT-based relapse prevention, often with contingency management.

Answer: (D)

Evidence-based treatment for substance use disorders relies on strategies that engage motivation, build concrete coping skills, and reinforce abstinence over time. The strongest approach blends Motivational Interviewing—an empathetic, client-centered method to strengthen intrinsic motivation—with Cognitive Behavioral Therapy–based relapse prevention, which teaches practical skills for avoiding triggers, managing cravings, and handling high-risk situations. Often, this combination is enhanced by contingency management, which uses tangible rewards to reinforce abstinence and treatment engagement. Together, these components form an evidence-supported package that addresses both the motivational and behavioral aspects of change and has robust data across substances.

Purely motivational interviewing, while valuable for engagement, does not by itself provide the relapse-prevention skills that sustain long-term abstinence. Psychoanalysis and client-centered therapy lack strong, consistent evidence for improving SUD outcomes compared with structured behavioral treatments. Medication-only pharmacotherapy without counseling tends to be less effective than integrated approaches that combine medication with behavioral interventions, though medications play a crucial role in many cases when used as part of a comprehensive plan.
