Acceptance and Commitment Therapy on the NCMHCE: The Hexaflex, Defusion, Values, and How ACT Differs From CBT
By David Zimmerman · 8 min read · Clinical content
Acceptance and commitment therapy is on NBCC’s list of the frameworks counselors reported using most[3], and it is tested by its own vocabulary: psychological flexibility, experiential avoidance, cognitive fusion and defusion, values, committed action, self-as-context, creative hopelessness. The model is Hayes, Strosahl, and Wilson’s[1][2]. This post covers the hexaflex, the techniques, the difference from CBT and REBT that the exam likes to test, a sorter, and seven scenarios.
The hexaflex
| Process | Its opposite (inflexibility) | What the counselor does |
|---|---|---|
| Acceptance | Experiential avoidance | Willingness exercises; making room for the sensation or feeling; "can you have this and still do what matters?" |
| Cognitive defusion | Fusion (thoughts taken as literal truth or commands) | "I'm having the thought that…"; silly voices; word repetition; thanking the mind; leaves on a stream |
| Present-moment awareness | Living in the past or future; autopilot | Brief mindfulness, grounding, noticing exercises |
| Self-as-context | Attachment to the conceptualized self ("I am an anxious person") | The observer exercise; sky and weather; chessboard metaphor |
| Values | Lack of clarity or contact with values | Values clarification (bull's-eye, funeral or 80th-birthday exercise); values vs. goals |
| Committed action | Inaction, impulsivity, avoidance | Values-based goals with willingness; behavioral activation; exposure framed as willingness |

ACT vs. CBT vs. REBT
| ACT | Cognitive therapy (Beck) | REBT (Ellis) | |
|---|---|---|---|
| Target | The function of thoughts and the struggle with them | The content and accuracy of automatic thoughts and beliefs | Irrational, demanding beliefs |
| Method | Defusion, acceptance, values, mindfulness | Socratic questioning, evidence, behavioral experiments | Active disputation (logical, empirical, pragmatic) |
| Goal | Psychological flexibility; valued living with symptoms present | More accurate, adaptive thinking; symptom reduction | Rational beliefs; unconditional self-acceptance |
| Exposure | Framed as willingness in the service of values | Framed as testing predictions | Shame-attacking and risk-taking exercises |

Acceptance and commitment therapy on the NCMHCE
A client with panic disorder has organized her life around avoiding any situation where she might feel her heart race. An ACT counselor would conceptualize the core problem as:

Frequently asked questions
What are the six core processes of ACT?
Acceptance, cognitive defusion, present-moment awareness, self-as-context, values, and committed action (the hexaflex). Together they define psychological flexibility; their opposites (experiential avoidance, fusion, autopilot, attachment to a conceptualized self, unclear values, inaction) define the problem ACT treats.
How is ACT different from CBT?
Cognitive therapy examines and corrects the content of thoughts; ACT changes the client's relationship to thoughts (defusion) and the willingness to have feelings (acceptance) so that behavior can follow values now rather than waiting for symptoms to leave. Exposure in ACT is framed as willingness in the service of values.
What is creative hopelessness in ACT?
An early-phase review of the client's attempts to control or eliminate unwanted thoughts and feelings, their limited success, and their costs. It is hopelessness about the control strategy, not about the person, and it opens the door to acceptance and values-based action.
