Abstract	In the present study, the psychometric properties of the German version of the Posttraumatic Diagnostic Scale (PTDS; A. Ehlers, R. Steil, H. Winter, & E. B. Foa, 1996) were evaluated in a sample of 143 trauma survivors. To investigate convergent and discriminant validity of this questionnaire, the authors assessed posttraumatic stress disorder (PTSD), anxiety, depression symptoms, and social phobia. Internal consistencies of the PTDS and its subscales as well as their association with related measures show that the German PTDS is a reliable and valid instrument for the assessment of posttraumatic stress symptoms. A 3-factor structure was found that is, however, not exactly in concordance with the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; American Psychiatric Association, 2000) formulation (Reexperiencing, Avoidance, and Hyperarousal) but rather comprises a Reexperiencing/Avoidance factor; an Emotional Numbing/Hyperarousal factor; and a 3rd factor, consisting of Hypervigilance and an Exaggerated Startle Response. The findings are discussed with respect to their equivalency to the original PTDS, core symptoms of PTSD, and desirable future research. (Author).
