title: Reliability and validity of the Korean version of the Davidson Trauma Scale.
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 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.
