Psychometric properties of the Korean version of the Short Post-Traumatic Stress Disorder Rating Interview (K-SPRINT)

Aims: The Short Post-traumatic Stress Disorder (PTSD) Rating Interview (SPRINT) is a validated, eight-item, brief global assessment scale for PTSD. This report investigated the psychometric properties of the Korean version of the SPRINT (K-SPRINT). Methods: Eighty-seven PTSD patients, 47 other psychiatric patients, and 63 healthy control subjects were enrolled in the study. All subjects completed a psychometric assessment package that included the K-SPRINT and the Korean versions of the Clinician-Administered PTSD Scale (CAPS), the Beck Depression Inventory (BDI), and the State Trait Anxiety Inventory (STAI). Results: The K-SPRINT showed good internal consistency (Cronbach's α = 0.86) and test-retest reliability (r = 0.82). K-SPRINT showed moderatecorrelations with CAPS (r = 0.71). An exploratory factor analysis produced one K-SPRINT factor. The optimal diagnostic efficiency (91.9%) of the K-SPRINT was found at a total score of 15, at which point the sensitivity and specificity were 90.8% and 92.7%, respectively. Conclusions: The present findings demonstrate that the K-SPRINT had good psychometric properties and can be used as a reliable and valid instrument for the assessment of PTSD.
