How they work

CPT

Core mechanism: Identifying and challenging stuck points (distorted trauma-related beliefs) restores balanced appraisals of safety, trust, power, esteem, intimacy

Ontology: Trauma disrupts pre-existing beliefs or generates distorted accommodations about self and world

Motivational Interviewing

Core mechanism: Resolving ambivalence through evocation of client's own change talk; autonomy support increases intrinsic motivation

Ontology: Ambivalence about change is normal; confrontation increases resistance, empathy reduces it

What each assumes — and misses

CPT

Philosophical roots: Beck (cognitive model); Horowitz (stress response theory); Piaget (accommodation/assimilation); constructivism (meaning is actively constructed)

Blind spots: Cognitive focus may underemphasize somatic and emotional processing; structured protocol can feel rigid

Therapeutic voice: You wrote that the assault was your fault because you didn't fight back. Let's look at that stuck point together.

Motivational Interviewing

Philosophical roots: Rogers (empathy, autonomy); Kierkegaard (stages, either/or); Festinger (cognitive dissonance); Deci & Ryan (self-determination theory)

Blind spots: Not a standalone treatment for most conditions; may feel insufficient when clients need more than ambivalence resolution

Therapeutic voice: On one hand you want to stop, and on the other hand it's serving an important function. What would you lose if you quit?

Choosing between them

CPT (Cognitive-Behavioral) and Motivational Interviewing (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.
