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
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?"
View of the Person
An autonomous agent with intrinsic motivation for change that emerges when ambivalence is respectfully explored rather than confronted
Evidence
NICE: referenced for alcohol use. VA/DoD: referenced within MI recommendations
Tested in Project MATCH (1997) and COMBINE (2006) — two of the largest alcohol treatment trials ever conducted
Included in Lundahl et al. (2010) MI meta-analysis
Project MATCH found MET (4 sessions) produced outcomes comparable to 12-session CBT and 12-session TSF for alcohol dependence. COMBINE trial confirmed effectiveness. The key innovation was structuring MI into a reproducible, testable protocol.

How does MET differ from MI?
Show answer
MI is a clinical style applicable across contexts and sessions. MET is a specific 4-session manualized protocol developed for Project MATCH that structures MI techniques into a fixed treatment format with personalized assessment feedback.
