Psychometric properties of the Persian version of the Acceptance and Action Questionnaire for obsessions and compulsions (AAQ-OC)

Experiential avoidance (EA) is an important component of acceptance and commitment therapy. In recent years, various questionnaires have been designed to assess this construct, including a version relevant to obsessions, referred to as the Acceptance and Action Questionnaire for Obsessions and Compulsions (AAQ-OC). The aim of this study was to examine the psychometric properties of a Persian version of the AAQ-OC in a student sample (N = 334). Participants were administered the AAQ-OC, and several other measures that assessed general EA, depression, anxiety, stress, and obsessive-compulsive symptoms. Exploratory factor analysis revealed a two-factor model for the AAQ-OC (factor 1: Valued Action; factor 2: Willingness). AAQ-OC and its Valued Action and Willingness subscales had satisfactory internal consistency and test-retest reliability, although the Willingness subscale had relatively lower test-retest reliability. In relation to convergent validity, the AAQ-OC and the Valued Action subscale had positive associations with a measure of general EA. In relation to construct validity, the AAQ-OC and the Valued Action subscale had positive associations with measures of depression, anxiety, stress, and obsessive-compulsive symptoms. Overall, this study provides initial support for the reliability and validity of the Persian version of the AAQ-OC. Further evaluation of the Willingness subscale is also warranted.
