Acceptance and Commitment Therapy
Acceptance and Commitment Therapy (ACT) is a form of behavioral therapy that focuses on helping individuals accept their internal experiences rather than fighting or avoiding them. ACT was developed in the 1980s by Steven C. Hayes and is grounded in principles of Relational Frame Theory (RFT) and combines aspects of mindfulness, acceptance, and behavioral change strategies.
Unlike traditional cognitive-behavioral therapy (CBT), which often focuses on challenging and changing the content of thoughts, ACT emphasizes changing one’s relationship with thoughts and feelings. The goal is to help individuals live a meaningful and values-driven life while making space for painful experiences that are inevitable.
At its core, ACT promotes psychological flexibility — the ability to stay present and open to experiences while acting in ways that are consistent with one’s values.
The Six Core Processes of ACT
ACT is structured around six interconnected core processes that help foster psychological flexibility:
- Cognitive Defusion: Learning to step back from thoughts and see them as just that — thoughts, not truths or commands. For example, instead of “I must wash my hands or something bad will happen,” the individual learns to see this as a mental event, not a literal fact.
- Acceptance: Making room for unpleasant feelings, urges, and sensations rather than avoiding or suppressing them. Acceptance does not mean liking these experiences but allowing them to be present without struggle.
- Contact with the Present Moment: Practicing mindfulness to stay in the “here and now,” rather than ruminating on the past or worrying about the future.
- Self-as-Context: Developing a sense of self that is separate from one’s experiences — recognizing that one is not defined by their thoughts or feelings.
- Values: Identifying what truly matters to the individual, such as relationships, honesty, creativity, or helping others.
- Committed Action: Taking steps toward values-based goals, even in the presence of discomfort, anxiety, or doubt.
