Schmalz, J. E., & Murrell, A. R. (2010). Measuring experiential avoidance in adults: The Avoidance and Fusion Questionnaire. International Journal of Behavioral Consultation and Therapy, 6, 198-213.
To date, general levels of experiential avoidance are primarily measured by the Acceptance and Action Questionnaire - II (AAQ-II) but it includes items of questionable comprehensibility. The Avoidance and Fusion Questionnaire for Youth (AFQ-Y), previously validated as a measure of experiential avoidance with children and adolescents, was investigated as a measure with adult college students. The AFQ-Y evidenced adequate reliability (α = .92) and appropriate convergent and divergent validity in this sample. Interestingly, AFQ-Y and AAQ-II scores, thought significantly related, were not so closely related as to say they measure the same construct. The implications of this and future directions for measurement development are discussed.
