Acceptance and Commitment Therapy (ACT) is based on the idea that the language used for thoughts has a direct impact on one’s psychological flexibility and adaptability. One strong element of ACT involves identifying the words one uses to formulate ideas, fears, and avoidances and replace them with a more constructive vocabulary for thought. ACT can take many forms, and there are multiple online and print resources on the subject which can be worked on with a qualified therapist, or independently as an effective self-help technique.
