Reading focus

Syllabus: How Can Working With Emotion, Awareness and Acceptance Promote Change?

Connect acceptance and defusion to values and committed action rather than treating reduced discomfort as the sole goal.

Why you’re reading it. Introduce a second account of how a person’s relationship to experience may change.

A question to consider. If anxiety persists but someone resumes a valued activity, what would you measure to judge whether that change is helpful and freely chosen?

Why this reading

This account links acceptance to acting in accordance with personally chosen values. It offers a substantive explanation of how changing a thought’s influence on behavior might matter even when the thought still occurs.

Before you read

Psychological flexibility means responding to circumstances while pursuing valued directions. Defusion means changing how one relates to a thought. Relational frame theory is the authors’ behavioral account of language; its technical vocabulary takes time.

Read for

  1. Connect the six processes in Figure 2 with the functions they are meant to serve.
  2. Distinguish laboratory principles, clinical illustrations, process associations and treatment-outcome comparisons.

Consider afterwards

  1. How could a person become more flexible while reporting the same level of anxiety?
  2. What evidence would distinguish valued action from merely complying with a therapist’s priorities?

Editorial context

This developer-authored 2006 synthesis presents an early evidence base. It does not establish that every process is necessary, unique to ACT or causally demonstrated. Acceptance concerns a relationship to experience; it need not imply endorsement of harmful circumstances. Later outcome syntheses also depend on which studies and comparators they include.
