Background: Early trauma-focused cognitive-behavioural therapy (TFCBT) holds promise as a preventive intervention for people at risk of developing chronic post-traumatic stress disorder (PTSD). The aim of this review was to provide an updated evaluation of the effectiveness of early TFCBT on the prevention of PTSD in high risk populations.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
