다국어 초록 (Multilingual Abstract)

Objectives : The present study was conducted to explore the reliability and validity of the "Impact of Event Scale-RevisedKorean version" (IES-R-K).
Methods : The subjects were college students who visited a college counseling center and patients who were admitted to a general hospital and two orthopedic local clinics.Those subjects who experienced catastrophic traumatic events were tested for CAPS, BDI, STAI-I, II, and MMPI-PTSD scale.
Results : The range of correlations between item-total were .45 -.89. The coefficients of internal consistency were .69 -.83, of them were the Split-half reliability was .71 and the test-retest reliability was .89, all within expected ranges. Inter-corre-lations of IES-R-K, CAPS, BDI, STAI-I, II, and MMPI-PTSD scale were high. CAPS showed the highest correlation Coef-ficient. Factor analysis indicated 4 factors in IES-R ; avoidance, hyperarousal, intrusion, and sleep problem & numbness. IES-R-K can be a useful self-rating diagnostic instrument for PTSD symptoms to be a clinical concern by using 24/25 cutoff in total score. The partial PTSD cutoff score is 17/18.
Conclusion : The IES-R-K was confirmed in it's reliability and validity. IES-R-K could be applied for screening of PTSD.
