Objective: The study explores the psychometric characteristics of "Barndomsupplevelser", a Swedish translation of the 53-item version of the Childhood Trauma Questionnaire (CTQ). Method: Fifty-five female addicts, treated at a compulsory care setting completed the questionnaire. Homogeneity and reliability was studied using Principal component analyses (PCA) and Cronbach´s alpha. The test was submitted to content analysis. Results: Nearly all (94,5 percent) had experienced childhood abuse or neglect. The internal consistency is high. The 4-factor solution corresponded to the subscales of emotional and physical abuse (combined), of sexual abuse and of emotional neglect, while the items in the physical neglect subscale were distributed to several factors. In the 5-factor solution, this subscale was divided into two factors. Content analyses of these factors point to other meanings than physical neglect. Conclusion: The CTQ (Swedish translation) was found to have high consistency and homogeneity in four of the five subscales (emotional, physical and sexual abuse and emotional neglect), while the subscale on physical neglect may need revision. The new 28-item brief version seems to be an improvement, in regards to these problems.
