The unwillingness to remain in contact with obsessions and anxiety (i.e., experiential avoidance, EA) may explain how normally occurring unwanted intrusive thoughts develop into clinical obsessions as seen in obsessive-compulsive disorder (OCD). Studies examining the relationship between EA and OC symptoms are mixed, potentially because the existing self-report measure of EA (i.e., the Acceptance and Action Questionnaire, AAQ-II) is a general measure that does not adequately capture EA specific to obsessions and compulsions. Thus, we aimed to develop and evaluate an OC-specific version of the AAQ-II. First, we used exploratory factor analysis to empirically reduce an initial pool of 49 items (adapted from original AAQ-II items to reference “intrusive thoughts”) to 13 items. A two-factor solution (Valued Action and Willingness) provided the best fit to the data, accounting for 60.57% of the variance. Second, the reduced AAQ-OC was administered, along with other self-report measures, to an independent sample of adults. The AAQ-OC subscales evidenced good internal consistency as well as convergent, discriminant, and incremental validity. Future work examining the psychometric properties of the AAQ-OC in a clinical sample, as well as the measure's treatment sensitivity are needed. •We aimed to develop a version of the AAQ specific to obsessions and compulsions.•We examined the factor structure, reliability, and validity of the AAC-OC.•We explored relationships with OC symptom dimensions and related cognitions.•AAQ-OC demonstrates a two-factor structure and strong internal consistency.•The AAC-OC demonstrated convergent, discriminant, and incremental validity.
