The Davidson Trauma Scale (DTS) is a validated, 17-item, brief global assessment 
scale for posttraumatic stress disorder (PTSD). The purposes of this study were 
to develop a Korean version of the DTS (DTS-K) while maintaining its basic 
structure and to evaluate its reliability and validity for the Korean 
population. Participants of this study included 93 patients with PTSD (PTSD 
group), 73 patients with nonpsychotic mood or other anxiety disorders 
(psychiatric control group), and 88 healthy controls (normal control group). 
Subjects completed psychometric assessments, including the DTS-K and the Korean 
version of the Clinician-Administered PTSD Scale and the State Trait Anxiety 
Inventory. The DTS-K showed good internal consistency (Cronbach alpha = .97) and 
test-retest reliability (r = .93). The DTS-K showed a significantly positive 
correlation with Clinician-Administered PTSD Scale (r = .94). The highest 
diagnostic efficiency of DTS-K was at a total score of 47, with sensitivity and 
specificity of 0.87 and 0.84, respectively. Our findings suggest that the DTS-K 
is composed of good psychometric properties and is a valid and reliable tool for 
assessing the frequency and severity of PTSD symptoms regardless of ethnicity.
