Abstract:
OBJECTIVES: The purpose of this study was to examine the reliability and validity of A ClinicianAdministered PTSD Scale(CAPS). METHODS: CAPS was administered to 28 PTSD subjects, 30 non-PTSD subjects, and 36 normal subjects. Interrater reliability for the CAPS was established by interviewing 10 PTSD subjects. The interviews were conducted by 2 interviewers simultaneously. The authors adminstered to all the subjects Impact of Event Scale(IES), Beck Depression Inventory(BDI), State Trait Anxiety Inventory I, II (STAI-I, II) for measuring concurrent validity. RESULTS: The value of Cronbach's alpha and interrater agreement were .95 and .89, respectively. The CAPS was highly correlated with IES(r=.80), BDI(r=.70), STAI-II(r=.56). But the CAPS was not correlated with STAI-I(r=.20). The CAPS showed an overall agreement with clinical diagnosis of 82.1%. CONCLUSIONS: The CAPS shows a reasonable degree of reliability and validity. The CAPS could be a valuable tool to diagnose PTSD.
