Psychometric Properties of the ITQ for Measuring ICD-11 Complex PTSD in a Spanish Sample of Women Survivors of Intimate Partner Violence

Complex posttraumatic stress disorder (CPTSD) is related to prolonged, multiple, and interpersonal exposure to traumas. Several studies in different populations have focused on implementing the International Trauma Questionnaire (ITQ) to assess PTSD and CPTSD, though not in women survivors of intimate partner violence. The aim was to assess the psychometric properties of this measure in this population. The results obtained for this sample ( N = 340) indicated excellent internal ITQ reliability. Moreover, a six-factor CPTSD first-order correlated model was considered, and concurrent validity supported ITQ administration to this population.
