Abstract

The Composite International Diagnostic Interview Post Traumatic Stress Disorder module (CIPI-PTSD) was tested in five sites. 91 subjects were given the CIDI-PTSD and an independent clinician completed a diagnostic checklist for DSM-IIIR and ICD10 diagnoses. The internal consistency of the scale was acceptable for DSM-HIR (Cronbach's α = 0.86) and for ICD10 (Cronbach's α = 0.76). The concurrent validity of the CIDI-PTSD with diagnoses made by a clinician was good for ICD10 diagnoses (κ = 0.66) but poor for DSM-IIIR diagnoses (κ = 0.26). When the criterion addressing duration of the disorder for DSM-IIIR was removed, however, the agreement between the CIDI-PTSD and the clinical diagnosis was much improved (κ = 0.55). On the basis of these preliminary data, it is concluded that the CIDI-PTSD be examined further as a diagnostic instrument for PTSD.
