1999 Marmara depremini yaşamış kişilerle yapılan bu araştırmada psikiyatride hastalık tanısı koymada kullanılan iki farklı ölçüt grubunun denkliği araştırılmıştır. Araştırma sonuçları birisi ABD de diğeri Avrupa’da daha sık kullanılan bu iki tanı koyma sisteminin bazı farklılıklar gösterdiğini ve uyumlu olmaları için düzenlemeler yapılmasının gerekliliğini göstermiştir. Araştırma sonuçları Amerikan Psikiyatri Birliği’nin Kanada’da yapılan 2006 yılı toplantısında sunulmuştur.

Introduction: Researches and epidemiological studies will be hampered by the discrepancies between the diagnostic systems.The aim of this study was to examine whether the participants receiving an ICD-10 diagnosis of Posttraumatic Stress Disorder (PTSD) will also receive a DSM-IV diagnosis of PTSD.
Methods: Data were obtained for 90 participants who survived the Marmara earthquake. The Composite International Diagnostic Interview 2.1 used to assess the PTSD for DSM-IV and ICD-10 Diagnostic Criteria for Research (ICD-10 DCR).
Results: Thirty-two of ninety participants did not get a diagnosis of PTSD on either diagnostic system. 46.7% (n=42) of participants were given a diagnosis of PTSD by both diagnostic systems. Thus there was 82.2% agreement between the two diagnostic systems. The 12 month prevalence of PTSD in this sample is 46.7 % (42 out of 90) when DSM-IV criteria used, 64.4 % (58 out of 90) when ICD-10 DCR used. 68.8 % of discrepancies between two diagnostic systems occurred because participants were negative for DSM-IV criterion C but positive for ICD-10 DCR criterion C.
Conclusion: Some differences exist between the PTSD diagnostic criterion presented in the ICD-10 DCR and DSM-IV. The additional construct of general numbing of responsiveness in DSM-IV criterion C found to be an important cause of discrepancies between DSM-IV and ICD-10 DCR. The results of the present study shows that assumption of equivalency between ICD-10 and DSM-IV criteria for PTSD needs further testing.
