The first Randomized Controlled Trials using Acceptance and Commitment Therapy, or “ACT” started in 1986.  More than 30 years and 282 RCTs later, the Association for Contextual Behavioral Science (ACBS) has become a major player in the psychology and behavior analytic communities, with over 8,000 members listed in their directory, and their 17th annual World Conference coming up soon.

ACT is one of several behavioral approaches designed to explicitly leverage the power of language, and to overcome barriers inherent in language, to help people live meaningful lives.  Because language is so useful in our lives, it can sometimes overgeneralize and impair psychological functioning.  As a result, we can come to function in a world of language somewhat disconnected from more beneficial direct-acting contingencies in the environment.

Rather than changing our thoughts and feelings that may inhibit our wellbeing, ACT helps to undercut their functions such that we can contact contingencies that matter.  One organizing model within ACT is the hexaflex, which illustrates how core behavioral processes work together to produce psychological flexiblity, defined by Steve Hayes as “the ability to contact the present moment more fully as a conscious human being, and to change or persist in behavior when doing so serves valued ends.”

In a recent video by Brett DiNovi & Associates, Michelle Zube and Kate Rice, both Board Certified Behavior Analysts (BCBAs), provide an overview of the hexaflex.


Michelle and Kate note that a key element of defusion is to simply notice your thoughts as thoughts.  Defusion is the difference between looking at our thoughts as part of the world, vs looking at the world through our thoughts.  If you are defused, you are more likely to view your thoughts as behavior rather than “truth”.  The opposite of defusion is fusion, or believing your thoughts as “truth” or representing reality.  Defusion can lead to greater flexibility while fusion might lead to rigidity – both may or may not be useful or functional depending on the context.


Acceptance is the “A” in ACT.  Michelle and Kate relate acceptance to discomfort, something most of us actively try to avoid.  Discomfort can come in many forms, such as physical discomfort (e.g., pain, cold, etc…), or emotional or psychological discomfort (e.g., anxiety, depression, intrusive thoughts).  If we are accepting of discomfort, we will be more likely to persist in valued directions despite the discomfort.

Contact with the Present Moment

The present moment is always with us, yet language has a way of taking it away from us.  We might be in a staff meeting while thinking about troubles at home, or the vacation next weekend.  Or you might be overly concerned with how you will respond to your spouse during an argument instead of listening to what he/she is really saying.  Our thoughts can grab us, and pull us away from what is happening here and now.  These are stimulus functions of our language that can sometimes be maladaptive, and indicative of fusion and avoidance.  Contact with the present moment helps us better track the direct-acting contingencies present here and now, and take action in line with our values.

Self as Context

Self as context is one of three “selves” in the ACT and RFT literature.  Self as context refers to the verbally constructed perspective of “I” as something separate from “YOU”.  We call these relations deictic frames, and they are a core relational operant.  Self as context is distinguished from the content of our language (self as content) or the ongoing behavioral processes in relation to “I” (self as process).  As Michelle and Kate mention, the ability to see yourself in this way can facilitate perspective taking, empathy, and other outcomes.


Whereas Skinner may have thought of values as reinforcers, ACT views values as behavior.  As Michelle and Kate mention, from an ACT perspective, goals are not values.  Values cannot be achieved, they can only be enacted in our ongoing behavior.  The ability to clarify your own values can give you direction in life, help you evaluate whether your thoughts, actions, and goals are in the service of larger life directions, and help you track direct-acting contingencies in your environment that will lead you down a meaningful life path.

Committed Action

As Michelle and Kate describe, committed action is related to actively following through with goals aligned with your valued directions.  Committed action is inherently goal-directed.  As you encounter psychological road blocks along your journey of committed action, other ACT processes become useful.
