Objective: The PTSD Symptom-Self Report Scale (PSS-SR) is a widely used psychometric instrument in studies for assessing post-traumatic symptoms. In this study, we our aim was to address the psychometric properties of the Turkish version of the PSS-SR by assessing the validity of the original three-factor structure of the scale as well as concurrent validity and reliability. Methods: Participants were 596 college students and 20 patients with PTSD ex-perienced earthquake in Van and consequently applied to psychiatry clinic seek for treatment. 64.61 percent of the subjects were females (n=398). Mean age of the participants was 21.81±2.78. In the study, subjects were adminis-tered the PSS-SR, Impact of Event Scale (EIS-R), Dissociative Experiences Scale (DES), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). Validity of the original three-factor structure of the PSS-SR was assessed by using confirmatory factor analysis. Correlations between scores of the instrument and other psychological variables were calculated. Internal consistency and 15-day test-retest reliability of the instrument were assessed. Results: Findings obtained with confirmatory factor analysis replicated the validity of the original three-factor structure. Signifi-cant linkages of total and subscale scores of the PSS-SR to other psychological variables provided additional evidence for construct validity of the instrument. Internal consistency for total scale was 0.90 and for subscales ranged between 0.72-0.82. 15-day temporal stability coefficient for total scale was 0.66. Conclusion: The Turkish translation of the PSS-SR has adequate validity and reliability.
