BACKGROUND: The Acceptance and Action Questionnaire-Trauma Specific (AAQ- @entity1950 ) is a self-report measure designed to assess- @entity130 -related psychological (in)flexibility, as conceptualized in Acceptance and Commitment Therapy. However, there are no studies to date regarding its psychometric properties. This study explores such properties in the Portuguese version of the AAQ- @entity1950 , in Portuguese Colonial War Veterans. METHOD: A Principal Components Analysis (PCA) was conducted in a sample from the general population of war Veterans (N=371). Confirmatory Factor Analysis ( @entity3795 ) as well as reliability and convergent validity studies were performed in a different sample from the same population (N=312). For the discriminant validity a clinical sample with a war-related @entity1005 (N=42) and a non-clinical sample without @entity1005 (N=44) were used. RESULTS: The @entity3795 suggested a re-specified 15-item model with good global adjustment and factorial validity. The AAQ- @entity1950 showed internal consistency, a good temporal reliability, convergent validity with psychopathological symptoms (related to @entity1005 , @entity148 , @entity308 and stress) and peritraumatic dissociation (altered awareness and depersonalization/derealization). The questionnaire also discriminates between war Veterans with and without a @entity1005 diagnosis. LIMITATIONS: The major limitation relates to the samples' characteristics and sampling methods, which can limit the generalization of results. CONCLUSION: The Portuguese version of the AAQ- @entity1950 is a reliable and valid measure to assess experiential avoidance related to @entity130 in Portuguese Colonial War Veterans.
