Description
Summary:	Aim: This study aims to provide a brief questionnaire form of the Neuropsychiatric Inventory (NPI-Q) in Korean translated from the original NPI-Q that is intended for the evaluation of behavioral and psychological symptoms of dementia in routine clinical practice. Patients and Methods: We developed a Korean version of the NPI-Q (KNPI-Q) and compared subitems with those of the Korean version of the NPI (KNPI) in 63 dementia patients; 47 patients had been diagnosed with Alzheimer's disease with dementia, 8 with vascular dementia, and 8 with dementia with Lewy body disease. The diagnosis was based on the National Institute of Neurological and Communicative Disorders and Stroke - Alzheimer's Disease and Related Disorders Association criteria for possible and probable Alzheimer's disease and the International Statistical Classification of Diseases and Related Health Problems, 10th revision, criteria for vascular dementia and other dementing diseases. All patients received the Korean version of the Mini-Mental State Examination and the Clinical Dementia Rating within 1 month of the KNPI-Q. Results: Test-retest reliability of the KNPI-Q using a Pearson correlation index was r = 0.89 for the total symptom scale and r = 0.90 for the distress scale. The prevalence of analogous symptom ratings differed by less than 6.7%. Convergent validity between the KNPI-Q and the NPI using a Pearson correlation index was r = 0.879 for the total symptom scale and r = 0.92 for the distress scale. Conclusions: The KNPI-Q is a reliable and brief instrument that can be employed for screening in the evaluation of neuropsychiatric symptoms of dementia and associated caregiver distress. It may be suitable for use in general clinical practice and could be administered as a brief neuropsychiatric interview.
