Abstract
The Acceptance and Action Questionnaire (AAQ-II) is an instrument designed to assess individual differences in psychological flexibility, as conceptualized within Acceptance and Commitment Therapy (ACT). The main purpose of the present study was to provide preliminary data on the psychometric properties and factor structure of the Romanian AAQ-II. Internal consistency for the Romanian version of the AAQ-II was found to be adequate. Correlational analyses with theoretically related measures sustained the convergent validity of this questionnaire. Two models were tested via CFA to assess the factorial validity of the Romanian version of the AAQ-II in a young non-clinical adult sample (n=350). Both models were specified as a one-dimensional solution, with the second model implying a correlated errors component between the positively formulated items. Our results seem to support a one-dimensional factor structure, suggesting that the apparent presence of a second factor is primarily due to a method effect (positively worded items). These findings are similar to those reported for the original version of the AAQ-II, and for other validated versions. Overall, our results recommend the Romanian version of the AAQ-II as a valuable tool for Romanian language population-based research on psychological flexibility.
