Abstract
The Avoidance and Fusion Questionnaire for Youth–Eight-Item Short Version (AFQ-Y8) assesses psychological inflexibility in youth. The present study is the first to examine alternative measurement models for the Greek adaptation of the AFQ-Y8, latent associations with the Acceptance and Action Questionnaire–II (AAQ-II), gender-group invariance, and latent mean comparisons between males and females. In total, 432 students from seven high schools in Cyprus participated in the study. Both a unidimensional and a two-dimensional model had excellent fit, although the one-factor solution was substantively superior. The correlation of the latent AFQ-Y8 factor with AAQ-II was strong and positive, indicating good convergent validity. Finally, the unidimensional AFQ-Y8 model was found to be invariant for gender and no latent means difference was detected between males and females.
