The Avoidance and Fusion Questionnaire for Youth (AFQ-Y) is a self-report measure for adolescents. The questionnaire assess cognitive fusion and experiential avoidance as described by Acceptance and Commitment Therapy (ACT). The aim of this study is to analyze psychometric properties and factorial structure of the Italian version of the instrument (I-AFQ-Y). The I-AFQ-Y was administered to 1248 students (aged between 11-18) in 12 schools. The EFA, performed on 604 participants recruited during study 1, shows a one factor solution named “Psychological Inflexibility”. CFA, performed on 644 students recruited during study 2, confirms different goodness of fit indices are adequate for the one-factor model. The I-AFQ-Y (8 item) shows moderate internal consistency (Cronbach’s alpha =.69 for the factor totale) and a moderate test-retest reliability (r=.64). Furthermore, the I-AFQ-Y shows a good convergent validity with internalizing problem scale (r = .53) and total problem scale (r = .52) of the YSR, while the correlation with externalizing problem scale is lower (r=.32). The short version of the I-AFQ-Y is a valid and reliable measure, that can be easily used both in research and in clinical practice.
