Cognitive Behavioral Analysis System of Psychotherapy (CBASP)
Cognitive Behavioral Analysis System of Psychotherapy (CBASP) is an integrative psychotherapy developed by James McCullough in 2000. Its 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. This catalogue links it to depression, typically in individual format, medium (16-24).

How Cognitive Behavioral Analysis System of Psychotherapy works
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

Condition-specific assessments
Each conclusion applies to the population and use described. These source-based assessments do not certify the full entry or replace expert clinical review.
Depression & Mood Disorders
Population and scope: Adults with chronic nonpsychotic major depression; trials distinguish initial treatment, medication nonresponse and early-onset chronic depression without antidepressants.
Randomized studies
Keller et al. (2000) randomized 681 adults: CBASP combined with nefazodone produced more responses than either alone after 12 weeks. In REVAMP (2009), adding CBASP to optimized medication for 491 initial nonremitters did not significantly improve depression outcomes over medication alone or supportive-therapy augmentation. A separate 268-person trial (2017) found CBASP superior to supportive psychotherapy on the 20-week primary depression measure in unmedicated early-onset chronic depression. These different treatment settings support randomized evaluation with mixed comparative results, not universal augmentation benefit or an assessment of every depressive presentation.

Read the recommendation and its scope. A source may discuss an approach without recommending it.
- Depression in adults: treatment and management, short version DRAFT
Discussed in the source
The draft named CBASP. Consultation material is not final guidance, and the final NG222 recommendations do not name CBASP.
Scope: Chronic depression and inadequate response in NICE’s July 2017 consultation draft.
- Depression in adults: treatment and management (NG222)
Discussed in the source
CBASP is not named in the final recommendation text inspected here. This does not establish its absence from all guideline evidence reviews or other organizations’ documents.
Scope: Final adult-depression recommendations in NG222.
Recorded material under review
The existing notes below are retained separately from assessment records. These recorded claims await source checking, including study design, recommendations and numerical estimates.
2 major RCTs (Keller et al., 2000: NEJM landmark study comparing CBASP + nefazodone)
Included in chronic depression meta-analyses
CBASP was designed for chronic depression. Keller et al. (2000) compared CBASP, nefazodone and their combination over 12 weeks. Its 2001 erratum clarifies that response/remission use weeks 10 and 12 for completer analyses and the endpoint for modified intention-to-treat analyses. Disciplined personal involvement uses the therapist’s own emotional reactions within the treatment model.

Clinical cautions and blind spots
Assessment and precautions
Active psychosis, acute suicidality, severe cognitive impairment, clients without chronic depression (the model was built for persistent depressive disorder)
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
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)
Compared with other approaches
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.
