Acceptance and Commitment Therapy
• It is said as one word, not letters
• A cognitive behavioral intervention that uses acceptance and mindfulness processes, and commitment and behavior change processes, to create psychological flexibility
![Page 3: Acceptance and Commitment Therapy Steven C. Hayes University of Nevada](https://reader033.vdocuments.net/reader033/viewer/2022061305/551400a3550346dd488b48c5/html5/thumbnails/3.jpg)
Psychological Flexibility
… is consciously contacting the present more fully, without needless defense, and based on what the situation affords, changing or persisting in behavior in the service of chosen values.
![Page 4: Acceptance and Commitment Therapy Steven C. Hayes University of Nevada](https://reader033.vdocuments.net/reader033/viewer/2022061305/551400a3550346dd488b48c5/html5/thumbnails/4.jpg)
ACTIs transdiagnostic: focused on
common core processes known to underlie many forms of psychopathology
This makes it broadly applicable, and especially well suited to multi-problem patients
![Page 5: Acceptance and Commitment Therapy Steven C. Hayes University of Nevada](https://reader033.vdocuments.net/reader033/viewer/2022061305/551400a3550346dd488b48c5/html5/thumbnails/5.jpg)
Expanding avoidance
All animals escape and avoid aversive events
![Page 6: Acceptance and Commitment Therapy Steven C. Hayes University of Nevada](https://reader033.vdocuments.net/reader033/viewer/2022061305/551400a3550346dd488b48c5/html5/thumbnails/6.jpg)
CAR
But only humans can readily bring aversive events into any setting
“Car”
![Page 7: Acceptance and Commitment Therapy Steven C. Hayes University of Nevada](https://reader033.vdocuments.net/reader033/viewer/2022061305/551400a3550346dd488b48c5/html5/thumbnails/7.jpg)
So We Try to Avoid Pain Itself
• Experiential avoidance is built into human language and then amplified by the culture– Experiential avoidance is the tendency to attempt to
alter the form, frequency, or situational sensitivity of historically produced negative private experience (emotions, thoughts, bodily sensations) even when attempts to do so cause psychological and behavioral harm
![Page 8: Acceptance and Commitment Therapy Steven C. Hayes University of Nevada](https://reader033.vdocuments.net/reader033/viewer/2022061305/551400a3550346dd488b48c5/html5/thumbnails/8.jpg)
ACTThis is a logical step, but it tends to
amplify pain or at least its impact, not decrease it
Especially toxic for those with difficult histories or physiology
Why toxic?

Don’t be anxious
Don’t think of a white bear
Self-Amplifying
