Acceptance and Commitment Therapy: ACT Theory and Practice
This paper provides an introduction to Acceptance and Commitment Therapy (ACT), a psychotherapy approach rooted in Relational Frame Theory. It examines how ACT differs from Cognitive Behavioral Therapy (CBT) by focusing on changing the function of thoughts rather than their content, and outlines the six psychological processes ACT targets: acceptance, defusion, being present, self as context, values, and committed action. Drawing on articles by Twohig (2012) and Hayes et al. (2012), the paper also addresses ACT's use of mindfulness techniques, its theoretical strengths, current limitations in the research base, and its potential application across a range of clinical presentations.

What makes this paper effective
- It opens with a clear conceptual distinction between ACT and CBT, immediately orienting the reader to the paper's central comparison and helping establish why ACT represents a meaningful development in psychotherapy.
- It balances theoretical explanation with an honest discussion of limitations, citing Hayes et al. (2012) to acknowledge the need for further empirical research rather than presenting ACT uncritically.
- The paper maintains a logical progression from theory, to core processes, to clinical practice — making complex psychological concepts accessible without oversimplifying them.
Key academic technique demonstrated
The paper demonstrates effective use of secondary source integration, drawing on two peer-reviewed journal articles to support both descriptive and evaluative claims. Rather than merely summarizing each source, the writer synthesizes them — using Twohig (2012) to outline ACT's mechanisms and Hayes et al. (2012) to critically assess its evidence base — showing how sources can serve different argumentative functions within the same essay.
Structure breakdown
The paper is organized into five logical sections: a theoretical introduction distinguishing ACT from CBT; an explanation of ACT's six target processes; a discussion of mindfulness and the observing self; an evaluation of current research strengths and weaknesses; and a closing section on practical clinical applications. This structure moves from the abstract to the applied, which is an effective approach for a therapy overview paper at the undergraduate level.
Introduction to ACT and Its Theoretical Foundations
Acceptance and Commitment Therapy (ACT) is a form of psychotherapy similar to Cognitive Behavioral Therapy (CBT). ACT is based on Relational Frame Theory, which developed out of cognitive therapy and supplied missing steps in Skinner's behaviorism by more deeply exploring the connections between language and thought. Essentially, ACT explores the idea that what and how a person thinks is highly impactful in that individual's daily life and functioning — and especially in how that person copes with stress. Whereas CBT focuses on altering the content of one's thoughts in order to move the individual toward a target behavior, ACT focuses on changing the function of thoughts so that they do not oppress the individual. ACT, in other words, focuses on the way in which a person interacts with their interior life.
Two articles that inform this discussion of ACT are "Acceptance and Commitment Therapy: Introduction" by Michael Twohig (2012) in Cognitive and Behavioral Practice, and "Acceptance and Commitment Therapy: Model, Processes and Outcomes" by Hayes, Luoma, Bond, Masuda, Lillis et al. (2012) in Behaviour Research and Therapy.
ACT's Six Core Psychological Processes
As Twohig (2012) notes, ACT targets six psychological processes for functional change within the therapy. These targets are "acceptance, defusion, being present, self as context, values and committed action" (Twohig, 2012, p. 499). By using a functionalist technique that focuses energy on these targets, ACT is able to assist the patient in accepting the part of the self that is problematic — as opposed to attempting to eradicate it.
The technique involves showing the patient that he or she possesses an observant self that can accept the experiences of the self without being oppressed by them. This allows the patient to transition not to a more "in control" phase of being, but rather to a more positive and accepting phase in which commitment to a new goal with new values can be developed. This commitment is based on the willingness of the objective self to proceed along the lines of the six target processes identified above.
