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

ProcessIts opposite (inflexibility)What the counselor does
AcceptanceExperiential avoidanceWillingness exercises; making room for the sensation or feeling; "can you have this and still do what matters?"
Cognitive defusionFusion (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 awarenessLiving in the past or future; autopilotBrief mindfulness, grounding, noticing exercises
Self-as-contextAttachment to the conceptualized self ("I am an anxious person")The observer exercise; sky and weather; chessboard metaphor
ValuesLack of clarity or contact with valuesValues clarification (bull's-eye, funeral or 80th-birthday exercise); values vs. goals
Committed actionInaction, impulsivity, avoidanceValues-based goals with willingness; behavioral activation; exposure framed as willingness

              GoalPsychological flexibility; valued living with symptoms presentMore accurate, adaptive thinking; symptom reductionRational beliefs; unconditional self-acceptance
              ExposureFramed as willingness in the service of valuesFramed as testing predictionsShame-attacking and risk-taking exercises

              The distractor pattern

              If an option has the counselor disputing or correcting the thought, it is not ACT. If it has the counselor waiting for the symptom to leave before action, it is not ACT either. The keyed ACT option notices the thought, makes room for the feeling, and moves toward a value now.

              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.
