This study was concerned with a culture-sensitive revision of the Turkish version of the Childhood Trauma Questionnaire (CTQ-28) and expansion of the instrument through integration of a dimension assessing overprotection – overcontrol (OP-OC). Participants (n = 783) were 37 dissociative and 78 non-dissociative and non-psychotic psychiatric outpatients, and 668 non-clinical people. They completed the revised and expanded version of the CTQ, Dissociative Experiences Scale, Beck Depression Scale, and Relationship Scales Questionnaire. A test-retest assessment was conducted on 25 non-clinical individuals.
