CBASP is the only psychotherapeutic approach created specifically for chronic depression. Not an adaptation of CBT, not a modification of IPT — a fully original system.
TIMELINE
James McCullough is an American clinical psychologist, professor at Virginia Commonwealth University (VCU). Working with chronically depressed patients, he discovered that standard approaches (CBT, IPT, psychodynamic therapy) work markedly less well in chronic depression than in episodic depression.
McCullough observed: chronically depressed patients function as though cut off from the environment. They do not see the link between their behavior and its consequences. Using Piaget's model of cognitive development, he described this as being "stuck" at the preoperational stage — in the interpersonal sphere.
CBASP works with:
30-35% of all depressions are chronic. It is not just "long depression" — it is a different disorder, with different mechanisms and a different response to treatment.
A central concept of CBASP. The chronically depressed person functions like a child at the preoperational stage (2-7 years of age in Piaget) — in the interpersonal sphere:
A deep conclusion about self / world formed in relationships with significant others. Not an "automatic thought" (as in CBT), but a causal theory: "since mother criticized me → I'm not good enough → everyone will criticize me".
A structured breakdown of a concrete situation: situation → interpretations → behavior → actual outcome (AO) → desired outcome (DO). If AO ≠ DO — find which interpretations and which behavior got in the way.
A unique technique: the therapist uses their authentic reactions as an instrument. "When you go silent — I feel sad. Is that the effect you want?" Not classic self-disclosure, but contingent reinforcement.
Helping the client discriminate past from present: the therapist ≠ the significant other. "I am not your mother. How are we different?"
| Phase | Sessions | Content |
|---|---|---|
| Assessment | 1-3 | Significant-other list, stamps, transference hypothesis |
| SA training | 4-6 | Situation analysis in session, learning the format |
| Active work | 7-16 | SA + DPI + IDE, transfer of skills |
| Closing | 17-20 | Updating stamps, relapse prevention |
| Parameter | CBT | IPT | CBASP |
|---|---|---|---|
| For whom | Episodic depression | Episodic depression | Chronic depression |
| Focus | Thoughts and behavior | Interpersonal roles | Link between behavior and consequences |
| Therapist | Teaching | Supportive | Personally involved (DPI) |
| Key technique | Cognitive restructuring | Role analysis | Situational Analysis |
| Past | Automatic thoughts | Interpersonal events | Significant others and stamps |
Standard CBT works less well in chronic depression because it relies on the client's ability to link thoughts and consequences. But that is precisely what the chronically depressed person cannot do. CBASP first TEACHES that link.
SESSION FORMAT (after the training phase)
1. Mood check (5 min) 2. Homework: review of SA done at home (15 min) 3. Situational analysis of a new situation (25 min) 4. DPI / IDE when needed (5-10 min) 5. Homework + summary (5 min)

CONTRAINDICATIONS
You are working with a person who has lived in depression for years and lost the sense that their actions affect the world. CBASP is the only protocol created specifically for chronic depression. The goal is to restore the link between behavior and consequences.
"The chronically depressed patient functions as if disconnected from the environment. They do not see the link between what they do and what they receive." — James McCullough
CBASP (Cognitive Behavioral Analysis System of Psychotherapy) was developed by James McCullough specifically for chronic / persistent depression. It is the only approach created entirely for this population. The largest trial (Keller et al., 2000, NEJM): CBASP + antidepressant = 85% improvement.
The key idea: the chronically depressed person is stuck at the preoperational stage (per Piaget) — unable to mentally trace the link "my behavior → consequences for the other". CBASP helps the shift to operational thinking in the interpersonal sphere.
CBASP does not start with a standard anamnesis but with the list of significant others (Significant Other History). This is a unique procedure: to identify the people who shaped the client's basic views of self and world.
For each significant other (usually 4-6 people): 1. Name and role (mother, father, teacher, partner) 2. How they treated the client — concretely 3. What the client felt 4. "Stamp" (causal theory closure): what conclusion about self/world the client drew
| Significant other | Treatment | Stamp |
|---|---|---|
| Mother | Criticized, devalued achievements | "I'm not good enough, whatever I do" |
| Father | Emotionally absent | "My feelings matter to no one" |
| First wife | Left after 10 years | "Closeness ends in loss" |
Stamps are not simply "negative thoughts" (as in CBT). They are deep causal conclusions formed in real relationships. They determine how the client "reads" any interpersonal situation.
Based on the stamps, formulate: "This client will expect from me…"
Situational Analysis is the central CBASP technique. A structured review of a concrete interpersonal situation: what happened → what was interpreted → what was done → what was received → what was wanted → what could have been done differently.
1. Situation: description — concrete, one situation, 1-2 minutes 2. Interpretations: "What did you think?" (record 2-3 interpretations) 3. Behavior: "What did you do? How did you act?" (concretely) 4. Actual outcome (AO): "How did it all end?" 5. Desired outcome (DO): "What did you want? What outcome would have been good for you?"
| Step | Question | Example |
|---|---|---|
| Situation | What happened? | A colleague did not reply to my message |
| Interpretation | What did I think? | "He doesn't care about me" / "I'm annoying him" |
| Behavior | What did I do? | Stopped writing, withdrew |
| AO (fact) | How did it end? | We stopped talking |
| DO (desired) | What did I want? | That he would reply and we'd continue |
If not (and usually they don't):
For each interpretation:
If not — what could have been done differently?
Key insight for the client: "My interpretations and behavior LED to the outcome. I'm not a victim — I'm a participant. And if I'm a participant — I can change the outcome."
A unique feature of CBASP: the therapist uses their authentic reactions — but disciplined and purposeful. This is not classic self-disclosure and not neutrality. It is "contingent reinforcement" from a real relationship.
| Form | When | Example |
|---|---|---|
| Positive reinforcement | Client did something new | "When you just looked at me and said what you feel — I felt warmth" |
| Negative reinforcement | Client returned to the old pattern | "When you go silent — I feel that you have left. It's hard for me to reach you" |
| Impact description | Always | "This is what I feel when you do that. Is that what you want?" |
DPI works because the chronically depressed client does not see how their behavior affects others. The therapist is the first person who gives direct, honest feedback.
IDE is a bridge between past and present. Help the client see: the therapist (and other people) is not their mother / father / ex. The stamp does not apply to everyone.
1. Recall the stamp from the significant-other list 2. Compare: does the therapist behave the same way as the significant other? 3. Pick out concrete differences 4. Help the client "update" expectations
1. SA at home — 1-2 situations per week, in writing 2. Impact journal — notice how your behavior affects others 3. Stamp check — "Did the stamp get confirmed in this situation?" 4. Practice of new behavior — one concrete action from the remediation phase
CBASP usually lasts 16-20 sessions. The last sessions consolidate skills and update the stamps.
A structured elicitation of the people who most influenced the client, and of the "stamps" (causal conclusions) formed in those relationships.

CBASP helps you see links between behavior, interpersonal consequences and the desired outcome.
By analyzing one concrete situation, you can notice interpretations, actions and their impact on others.
Write down the situation → thoughts → behavior → actual outcome (AO) → desired outcome (DO) → what could be different.
