AbstractBackground: Posttraumatic Diagnostic Scale (PDS) is a self-descriptive measure developed to provideinformation regarding posttraumatic stress disorder (PTSD) diagnosis and symptom severity.Objectives: The aim of this article is to report on the validation of the Polish version of PDS and to test itsfactor structure with reference to two models: an original three-factor model (Reexperiencing, Avoidance, andArousal) and alternative five-factor model (Reexperiencing, Avoidance, Numbing, Dysphoric Arousal, andAnxious Arousal).Method: The validation procedure included three studies conducted on samples of separate populations:university-level students (n 507), individuals who had experienced various traumas (n 320), and treatmentseekingsurvivors of motor vehicle accidents (MVA) (n 302). Various other measures of trauma-relatedpsychopathology were administered to participants, as well as the PTSD module of the Structured ClinicalInterview (SCID) in the case of MVA patients.Results: PDS showed high internal consistency and test retest reliability, good diagnostic agreement withSCID, good sensitivity but relatively low specificity. The satisfactory convergent validity was supportedby a large number of significant correlations with other measures of trauma-related psychopathology.Confirmatory factor analysis (CFA) generally confirmed both the three-factor structure and the alternativefive-factor structure of the questionnaire.Conclusions: The results show generally good psychometric properties of the Polish version of PDS.
