          Abstract

          This article reviews the conceptualization and empirical evidence of the midlevel process called cognitive defusion. First, it presents examples of cognitive fusion and cognitive defusion definitions that are offered in acceptance and commitment therapy (ACT) manuals; discusses their relationships with other ACT midlevel processes; and offers a relational frame theory (RFT) conceptualization of these processes. Second, it describes the type of cognitive defusion exercises and discusses the basic processes involved in them. Third, it reviews the measurement of cognitive (de)fusion in the form of self-report instruments, behavioral measures, and assessment in the clinical session. Fourth, it reviews the research on cognitive (de)fusion separated in laboratory research, survey research, and the analysis of processes of change in clinical trials. Lastly, it discusses some challenges and future directions in conceptualizing and researching cognitive (de)fusion.

            The development and initial validation of the cognitive fusion questionnaire.

            Acceptance and Commitment Therapy (ACT) emphasizes the relationship a person has with their thoughts and beliefs as potentially more relevant than belief content in predicting the emotional and behavioral consequences of cognition. In ACT, "defusion" interventions aim to "unhook" thoughts from actions and to create psychological distance between a person and their thoughts, beliefs, memories, and self-stories. A number of similar concepts have been described in the psychology literature (e.g., decentering, metacognition, mentalization, and mindfulness) suggesting converging evidence that how we relate to mental events may be of critical importance. While there are some good measures of these related processes, none of them provides an adequate operationalization of cognitive fusion. Despite the centrality of cognitive fusion in the ACT model, there is as yet no agreed-upon measure of cognitive fusion. This paper presents the construction and development of a brief, self-report measure of cognitive fusion: The Cognitive Fusion Questionnaire (CFQ). The results of a series of studies involving over 1,800 people across diverse samples show good preliminary evidence of the CFQ's factor structure, reliability, temporal stability, validity, discriminant validity, and sensitivity to treatment effects. The potential uses of the CFQ in research and clinical practice are outlined. © 2013.

              The emotional Stroop task and psychopathology.

              Attentional bias is a central feature of many cognitive theories of psychopathology. One of the most frequent methods of investigating such bias has been an emotional analog of the Stroop task. In this task, participants name the colors in which words are printed, and the words vary in their relevance to each theme of psychopathology. The authors review research showing that patients are often slower to name the color of a word associated with concerns relevant to their clinical condition. They address the causes and mechanisms underlying the phenomenon, focusing on J.D. Cohen, K. Dunbar, and J.L. McClelland's (1990) parallel distributed processing model.
