In this study, the factor structure of the Childhood Trauma Questionnaire short form (CTQ-SF) in a group of 123 female sex workers in the Netherlands was examined. Structural equation modeling was used to perform the confirmatory factor analysis. The fit between the five-factor model of Bernstein and Fink and the observed empirical model was good. The authors found a five-factor solution accounting for 66.65 percent of the variance. With the exception of one item ("I knew there was someone to take care of me and protect me"), factor analysis showed encouraging factor loadings. (Published Abstract)
