Abstract
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 α = .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.
