The current study tested the utility of the Implicit Relational Assessment Procedure (IRAP) as an analogue cognitive defusion intervention to alter implicit attitudes toward Abraham Lincoln and Adolf Hitler. One-hundred and twelve participants were randomly assigned to either a control or defusion condition. Participants first completed a series of self-report measures assessing psychological functioning and distress, as well as attitudes toward Lincoln and Hitler. Control condition participants then completed three IRAPs measuring implicit attitudes toward Hitler and Lincoln (H/L IRAP). Defusion conditions participants completed a pre-intervention H/L IRAP, received a rationale for defusion before completing a defusion IRAP, and then completed a post-intervention H/L IRAP. All participants finished the study by completing a second set of self-report measures. Results of the study indicated that when taking into account participant knowledge of defusion there were significant differences in IRAP performance post-intervention between conditions, although there were no significant differences in performance pre- to post-intervention within the defusion condition. Additionally, there were no differences between conditions on self-report measures at either time point, suggesting the IRAP was sensitive to changes in participant attitudes that self-reports were unable to detect. Thus, the results of this study indicate that the IRAP is a viable analogue defusion intervention, and future research should look to expand the defusion effect produced by the IRAP.
