CBASP is a form of psychotherapy first described in 1984 by James McCullough and expanded on in his full-length book Treatment for Chronic Depression: Cognitive Behavioral Analysis System of Psychotherapy (CBASP) published in 2000. Although its name sounds similar, it should not be confused with Cognitive Behavioural Therapy (CBT) or similar forms of therapy.
The goal of CBASP is to “teach the patient to focus on the consequences of behaviour, and to use problem solving to resolve interpersonal difficulties. (Driscoll, et. al., 2004, pg. 2)
A 2016 meta-review confirmed that CBASP is effective for the treatment of major depressive disorder, especially when combined with medication. (Negt, et. al., 2016), while a comparison of CBASP versus treatment-as-useful — other evidence-based therapies for depression — in Wiersma et. al. (2014) found that CBASP was at least as effective as the other treatments from 8 weeks up to 32 weeks but performed better by 52 weeks, suggesting it kept clients better, for longer.
Principles of CBASP
McCullough believes that depression is caused by “learned Pavlovian fears of interpersonal encounters, and maintained by a refractory pattern of Skinnerian interpersonal avoidance.” (McCullough, 2006) Essentially what this means is that clients develop a fear of relationships based on previous bad experiences that leads them to isolation and a disconnect from their environment.
CBASP involves the client completing paperwork called the Coping Survey Questionnaire (CSQ) in between each session. These CSQ forms are used to document stressful or challenging interactions with other people by exploring what happened, how the client reacted, and what the client wanted to happen. Then the CSQs are reviewed in therapy in a process known as Situational Analysis (SA).
According to Driscoll, et. al., (2004, pg. 4) analyzing one CSQ will likely take a full session in the beginning of treatment, but as a client masters the elements of the CSQ and the SA steps (described in more detail below) they will find themselves able to cover several CSQs in one session.
Five Steps of Situational Analysis
The five steps of Situational Analysis mirror the items on the CSQ.
Step 1. Describe the situation
In the first step, the client is expected to describe in 3 to 4 paragraphs a specific situation that occurred without editorializing or providing extraneous detail. The goal is for the therapist to be able to understand all of the interactions that occurred in that single instance.
Step 2. State interpretation
In step 2, the client provides their interpretations about what occurred during that conversation. Many times clients will make interpretations that are broad, based on situations that are very specific. For instance, a client who receives poor customer service from a cashier may state, “He wasn’t nice to me because I’m ugly.” Asking the client to provide two or three thoughts that occurred during the interaction, or asking the client what the situation meant to them in the moment may help spur the production of interpretations.
The most effective interpretations are those that lead to the desired outcome (DO), what the client wished had happened in that situation had it occurred again.
Step 3. Identify reactions
In step 3, the client records all of their own behaviours and reactions. These include voice tone, body language, pace, and other reactions the client may have had like walking away from the situation. This allows the client to identify avenues for changing behaviours to more easily reach the desired outcome.
Step 4. Explain the desired outcome (DO)
In step 4, the client explains the Desired Outcome (DO). The therapist can ask, “What were you trying to get out of this situation?” or “How did you want things to go” in order to spur this part of the conversation. One DO should be produced for each CSQ that is completed. These DOs should be SMART (specific, measurable, attainable, realistic and timely.)
One important element related to DOs is that they have to involve the client themselves. A DO can’t involve change in another person because we don’t have control over that person. What the client does have control over is their own reactions and responses.
Step 5. Illustrate the actual outcome (AO)
The actual outcome (AO) is perhaps the easiest step, because this explores what the client actually got out of the experience. Usually this is a negative experience but it doesn’t have to be — a positive AO may be an opportunity for the client to identify what went right and how they can repeat this in the future.
After Situational Analysis
After the SA phase is complete, the client has explained the situation, what happened, how they reacted, what they wanted to happen, and how the situation ended. This is known as the elicitation phase. The next stage of the two-part process is the remediation phase.
In the remediation phase of CBASP, the interpretations and behaviours are looked at to figure out if they’re the most useful beliefs or effective responses to the situation. If they’re not (and many times they aren’t), more effective interpretations and behaviours are suggested in order to help the client better reach the DO.
