This study examined the factor structure of the Acceptance and Action Questionnaire-II (AAQ-II) using exploratory and confirmatory factor analyses. Additionally, it evaluated the adequacy of its items and the number of response categories using item response theory (IRT). Participants consisted of 2,034 old adults dwelling in a community. A one-factor structure with covaried error terms was supported for six AAQ-II items. In contrast, the one-factor models in the 10-, 8-, and 7-item AAQ, as well as a correlated two-factor model, provided poor or inadequate fits, even after model modification. The four items of the AAQ-II excluded on the basis of the factor analyses also provided poor item fit based on the IRT. In addition, it was recommended to reduce the number of ratings for all items, instead of utilizing the 7-point rating used in the original AAQ-II scale. In conclusion, the six-item AAQ-II appears to be a unidimensional scale to measure experiential avoidance, and it is recommended to assess the applicability of a 5-point rating scale of AAQ-II items in future.
