How they work
Contingency Management
Core mechanism: Immediate, tangible reinforcement for abstinence directly competes with drug reinforcement; shifts behavioral economics of use
Ontology: Substance use maintained by powerful reinforcement contingencies; behavior follows reinforcement
Motivational Enhancement Therapy
Core mechanism: Personalized assessment feedback creates discrepancy between current behavior and values; structured MI within fixed sessions mobilizes intrinsic motivation for change
Ontology: Ambivalence about change is normal, not pathological; the person already has reasons to change but needs a structured space to resolve the conflict

Both treat
What each assumes — and misses
Contingency Management
Philosophical roots: Skinner (operant conditioning); Herrnstein (matching law); behavioral economics (Bickel — delay discounting); pragmatism (reinforcement works whether or not insight occurs)
Blind spots: Reinforcement effects may not persist after incentives end; ethical concerns about paying patients; limited to substance use
Therapeutic voice: For every clean urine sample, you get to draw from the prize bowl. Three in a row doubles your draw.
Motivational Enhancement Therapy
Philosophical roots: Rogers (empathy, autonomy); Festinger (cognitive dissonance); Bem (self-perception theory); Prochaska & DiClemente (stages of change)
Blind spots: Brief format may not address underlying drivers of addiction; feedback-based approach assumes the person values health norms; cultural assumptions in normative feedback
Therapeutic voice: Looking at your assessment results, your drinking is in the top 10% compared to people your age. How does that sit with you?
Choosing between them
Contingency Management (Behavioral) and Motivational Enhancement Therapy (Humanistic) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
