• The aim of the following paper was to adapt and validate the Portuguese version of the Acceptance and Action Questionnaire- II (AAQ-II), which measures Psychological Flexibility/Inflexibility, central components in Acceptance and Commitment Therapy. We assessed the psychometric properties of this scale in both general population and clinical samples. Exploratory Factor Analysis supported a single-factor structure with seven items and results from a Confirmatory Factor Analysis showed the goodness of fit of the model. This version also demonstrated a good level of internal consistency and good convergent and discriminant validity. Overall, the results stressed out that this Portuguese version of AAQ-II is a consistent and valid scale.
