Since these six factors exactly represented the areas that the interview was designed to assess, the construct validity of the Childhood Trauma Interview was supported. Principal-components analysis yielded six rotated factors that accounted for 74% of the variance among scores: separations and losses, physical neglect, emotional abuse or assault, physical abuse or assault, witnessing violence, and sexual abuse or assault. RESULTS: Interrater reliability for the majority of trauma dimensions measured by the Childhood Trauma Interview was very high (63% had intraclass correlations above 0.90). Convergent and discriminant validity for the Childhood Trauma Interview were tested by comparing correlations between analogous and nonanalogous trauma scales to those of the Childhood Trauma Questionnaire. METHOD: Drug- or alcohol-dependent patients (N = 220) were given the Childhood Trauma Interview and a questionnaire measure of child abuse, the Childhood Trauma Questionnaire. read more read lessĪbstract: OBJECTIVE: The Childhood Trauma Interview, a new instrument for brief and comprehensive retrospective assessment of childhood interpersonal trauma, is presented with initial evidence of its reliability and validity. CONCLUSIONS: These findings provide strong initial support for the reliability and validity of the Childhood Trauma Questionnaire. The Childhood Trauma Questionnaire also demonstrated good test-retest reliability over a 2- to 6-month interval (intraclass correlation = 0.88), as well as convergence with the Childhood Trauma Interview, indicating that patients' reports of child abuse and neglect based on the Childhood Trauma Questionnaire were highly stable, both over time and across type of instruments. Cronbach's alpha for the factors ranged from 0.79 to 0.94, indicating high internal consistency. RESULTS: Principal-components analysis of responses on the Childhood Trauma Questionnaire yielded four rotated orthogonal factors: physical and emotional abuse, emotional neglect, sexual abuse, and physical neglect. Sixty-eight of the patients were also given a structured interview for child abuse and neglect, the Childhood Trauma Interview, that was developed by the authors. METHOD: Two hundred eighty-six drug- or alcohol-dependent patients were given the Childhood Trauma Questionnaire as part of a larger test battery, and 40 of these patients were given the questionnaire again after an interval of 2 to 6 months. Abstract: OBJECTIVE: This report presents initial findings on the reliability and validity of a new retrospective measure of child abuse and neglect, the Childhood Trauma Questionnaire.
