Childhood Trauma Questionnaire (CTQ): Greek translation and psychometric validation in general and clinical population.

Exposure to childhood trauma experiences shows a high prevalence worldwide, with approximately two-thirds of the general population reporting traumatic experiences during childhood. The valid psychometric assessment of childhood trauma experience represents, however, a significant challenge in clinical research and practice. The Childhood Trauma Questionnaire - Short Form (CTQ-SF) embodies the most valid and internationally widely used tool for the retrospective assessment of traumatic experiences during childhood to date. The purpose of this study was the Greek translation of the questionnaire and its validation in both a general and clinical population. Participants completed electronically the Greek translation of the CTQ-SF, the Early Trauma Questionnaire (ETI-SR-SF), the Trauma Symptom Checklist (TSC-40), the Positive and Negative Affect Scale (PANAS- SF), the Well-Being Index (WHO-5) and the Patient Health Questionnaire (PHQ-4) to examine psychometric properties of the questionnaire (e.g., internal consistency, concurrent, convergent and divergent validity), but also to investigate the relationship between childhood trauma exposure and psychological well-being and symptoms of anxiety and depression. The total study sample (TS) consisted of 722 adults (606 women), of which 155 declared the existence of a psychiatric diagnosis (PD) and 567 constituted the general population (GP) sample. The most common trauma types reported were emotional abuse (29.1%), emotional neglect (23.7%), and physical abuse (24.6%). The CTQ-SF questionnaire showed high levels of internal consistency based on the Cronbach α coefficient (TS = 0.92, PD = 0.92, GP = 0.92), high concurrent and convergent validity and satisfactory convergent validity. In addition, self-reported childhood trauma was highly positively correlated to negative affect and anxiety and depression symptoms, as well as negatively to psychological well-being. Our results confirm that the Greek Version of Childhood Trauma Questionnaire (CTQ-SF) is a reliable and valid tool that can be used for the retrospective assessment of traumatic childhood experiences both in the general and in the clinical adult Greek population.
