title: Factor structure of the Cambridge Depersonalization Scale in trauma-exposed college students.
abstract: This study examined the factor structure of the Cambridge Depersonalization Scale (CDS; M. Sierra & G. E. Berrios, 2000 ), a 29-item self-report measure of depersonalization. The CDS was based on a conceptualization of depersonalization as a multidimensional construct, a theoretical perspective that has received limited empirical attention. Exploratory and confirmatory factor analyses were conducted on CDS item scores in a sample of 534 trauma-exposed college students. Results failed to support factor structures of the CDS previously reported in the literature and instead supported a 2-factor solution, with 1 factor representing a sense of unreality and detachment and a 2nd factor representing emotional and physical numbing. Implications regarding the structural validity of the CDS are discussed. [Supplementary material is available for this article.
