Abstract

Objective: To translate and validate the Chinese version of the Epilepsy Anxiety Survey Instrument (EASI) and its brief version (brEASI) among Chinese people with epilepsy.

Methods: Adult outpatients from Sichuan Provincial People's Hospital were recruited. The type of anxiety disorder was determined via the Mini International Neuropsychiatric Interview (MINI). All patients completed the Chinese version of the Generalized Anxiety Disorders-7 (GAD-7), the Chinese version of the Neurological Disorders Depression Inventory for Epilepsy (C-NDDIE), and the EASI/brEASI. Cronbach's α coefficient was calculated, and receiver operating characteristic (ROC) curves were analyzed.

Results: A total of 110 patients with epilepsy were included. Twenty-six (23.6 %) patients were found to have anxiety disorder according to the MINI criteria. The Cronbach's α coefficient for the Chinese brEASI was 0.873. In the study, the AUC of the brEASI for detecting all anxiety disorders was 0.883, and the optimal cutoff score was > 7, with a sensitivity of 92.3 % and a specificity of 72.6 %. For the diagnosis of non-GAD disorders, the brEASI had a greater AUC (0. 886) and performed better than the GAD-7 (AUC = 0. 824).

Conclusion: The Chinese version of the EASI and brEASI may be reliable and superior to the GAD-7 for anxiety screening in patients with epilepsy.
