RESUMEN
OBJECTIVE: The aim of this study was to evaluate the clinical reliability and validity of the Chinese version of the Neurological Disorders Depression Inventory for Epilepsy (C-NDDI-E). METHODS: A total of 248 Chinese patients with epilepsy underwent psychometric tests, including the Chinese version of the Mini International Neuropsychiatric Interview (C-MINI), the Chinese version of the Beck Depression Inventory - II (C-BDI-II), and the C-NDDI-E. RESULTS: None of the patients had difficulties understanding or completing the C-NDDI-E. Cronbach's α coefficient was 0.824. At a cutoff score of ≥14, the C-NDDI-E had a sensitivity of 0.854, a specificity of 0.899, a positive predictive value of 0.625, and a negative predictive value of 0.969. The scores for the C-NDDI-E were positively correlated with those for the C-BDI-II (P<0.001). CONCLUSION: The C-NDDI-E is a reliable and valid screening tool for the detection of major depression in Chinese patients with epilepsy.
