Abstract

Background: The Short Portable Mental Status Questionnaire is a brief cognitive tool designed to screen cognitive impairment in geriatric inpatients and outpatients. The validity and reliability of this tool have not been studied in Viet Nam so far. Objectives: Assess the diagnostic properties of the SPMSQ for detection of cognitive disorders in elderly and determine an appropriate cutoff point based on respondents’ level of education. Methods: This cross-sectional study was conducted through face-to-face interviews with 448 elderly people (≥ 65 years old) in four wards of Tan Phu district, Ho Chi Minh City from December 2021 to May 2022. Interviews will be conducted 2 times, 2 weeks apart, on the same subject. Results: Cronbach's alpha coefficient for SPMSQ is 0.72. The intraclass correlation coefficient is 0.89. Based on the DSM-5 criteria, the cut-off point of SPMSQ for the entire study population was 3 with sensitivity 87.5% and specificity 77.4%; AUC = 0.89. In elderly people with primary education or less, the cut-off point was 5, with sensitivity and specificity of 60% and 92.3%; AUC = 0.81. In elderly people with education above primary school, the cut-off point was 3 and the sensitivity and specificity were 85.6% and 85.9%; AUC = 0.91. Conclusions: The Vietnamese version of SPMSQ is valid and reliable enough to screen for cognitive disorders and can be used for cognitive screening of the elderly.
