title: Validity and reliability of a Persian version of the Childhood Trauma Questionnaire.
abstract: The purposes of this study were to translate the English version of the Childhood Trauma Questionnaire into Persian and to examine its psychometric properties. Reliability was examined using Cronbach coefficient alpha and corrected item-total correlation. A confirmatory factor analysis, based on a five-factor model, was performed using AMOS. Consecutive samples of 194 drug addicts, 197 psychiatric patients, and 599 college students were selected for the study. The mean age of participants (N = 1,000) was 24.8 yr. (SD = 7.1), and 49% were female. The test-retest reliability coefficient and the internal consistency reliability coefficient for the whole scale were suitable. The Childhood Trauma Questionnaire exhibited acceptable convergent validity with the General Health Questionnaire. A four-factor solution was selected as the most appropriate model using exploratory principal component analysis with oblique rotation. In conclusion, the Persian version of the Childhood Trauma Questionnaire showed acceptable psychometric properties.
