title: Reliability and validity of the Korean version of the Neurological Disorders Depression Inventory for Epilepsy (K-NDDI-E).
abstract: The Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) was developed as a screening instrument for rapid detection of major depression in people with epilepsy (PWE). We evaluated the reliability and validity of the Korean version of the NDDI-E (K-NDDI-E) in Korean PWE. This study applied to 121 outpatients who underwent psychometric tests including the Mini International Neuropsychiatric Interview-Plus Version 5.0.0, Beck Depression Inventory-II (BDI-II), and K-NDDI-E. The K-NDDI-E was easily comprehended and quickly completed by the patients. Cronbach's α coefficient was 0.898. At a cut off score of 11, the K-NDDI-E had a sensitivity of 84.6%, a specificity of 85.3%, a positive predictive value of 61.1%, and a negative predictive value of 95.3%. The scores of the K-NDDI-E had a positive correlation with those of the BDI-II (p<0.001). In conclusion, the K-NDDI-E is a reliable and valid screening tool to detect major depression in Korean PWE.
