CBASP
Core Mechanism
Situational analysis teaches cause-and-effect thinking about interpersonal encounters; interpersonal discrimination exercise separates therapist from maltreating early figures; disciplined personal involvement provides corrective experience
Ontology
Chronic depression involves developmental arrest at a pre-operational cognitive level (Piaget) due to early maltreatment: the person cannot perceive how their behavior affects others
Therapeutic Voice
"What did you want from that interaction? What did you actually do? Did your behavior get you what you wanted?"
View of the Person
A developmentally arrested being whose early maltreatment produced a pre-operational cognitive style that prevents perceiving the interpersonal consequences of their behavior
Evidence
Not named in NICE NG222 (2022); a 2017 draft guideline had considered CBASP for treatment-resistant depression, but that did not survive to the final published guideline
2 major RCTs (Keller et al., 2000: NEJM landmark study comparing CBASP + nefazodone)
Included in chronic depression meta-analyses
One of very few treatments designed specifically for chronic depression. Keller et al. (2000) NEJM study was landmark. Disciplined personal involvement, where the therapist deliberately uses their own emotional reactions, is unique and controversial.
Conditions
Epistemology
Blind Spots
Narrow application (chronic depression only); pre-operational framing may pathologize; disciplined personal involvement requires high therapist skill, since the model treats it as a trained technique rather than a boundary lapse and it is not safely improvised, so the practical constraint on using CBASP is whether a trained therapist is available; limited replication outside McCullough's group
Contraindications
Active psychosis, acute suicidality, severe cognitive impairment, clients without chronic depression (the model was built for persistent depressive disorder)
Training
CBASP training workshop + supervised practice. Disciplined personal involvement technique
McCullough Foundation
16-24 hrs + supervised cases

Philosophical Roots
Piaget (pre-operational thought: central to the model); Bowlby (early maltreatment shapes interpersonal schema); Sullivan (interpersonal theory); Bandura (social learning); Seligman (learned helplessness, which McCullough challenged)

Test Yourself
Why does CBASP target chronic depression specifically?
Show answer
McCullough argued chronic depression involves a distinct pre-operational cognitive style (Piaget): the person cannot perceive the connection between their behavior and its interpersonal consequences.
