title: Psychometric properties of the Norwegian version of the Childhood Trauma Questionnaire in high-risk groups.
abstract: The Childhood Trauma Questionnaire--Short Form (CTQ-SF) is widely used to measure childhood abuse of all types. In the present study, we examined the psychometric properties of the Norwegian version of the instrument. The participants constituted four subsamples (n = 517): substance abusers (n = 126), psychiatric patients (n = 210), prisoners (n = 109) and adolescents in out-of-home placements (n = 72). Confirmatory factor analysis revealed a reasonable fit of the data to the original five-factor structure of the CTQ-SF. Measurement invariance was found across gender and the four subsamples. It was concluded that the Norwegian version of the CTQ-SF has acceptable psychometric properties, with good reliability and satisfactory accuracy, to assess different dimensions of childhood trauma.
