Main Article Content
Abstract
Background: Dementia is a common health problem among older adults; causing hospitalization, loss of independence and reduced quality of life. The Short Portable Mental Status Questionnaire (SPMSQ) 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 population. Objectives: to assess the psychometric properties of the SPMSQ for detection of cognitive disorders in Vietnamese older adults. Methods: This cross-sectional study was conducted through face-to-face interviews with 334 elderly people (≥ 65 years old) in two communes Vinh Kim, Thuan Hoa, Cau Ngang District, Tra Vinh Province. Surveys were conducted at two timepoints, 2 weeks apart, on the same subject. Reliability was assessed by internal consistency using Cronbach’s alpha, test-retest reliability by intraclass correlation coefficient (ICC). ROC curve was performed to determine cut off point. Results: Cronbach's alpha coefficient for SPMSQ was 0.73. The ICC was 0.82. Based on the DSM-5 criteria, the cut-off point of SPMSQ for the entire study population was 4 with sensitivity 86.8% and specificity 74%; AUC = 0.86. Conclusions: The Vietnamese version of SPMSQ is valid and reliable enough to screen for cognitive disorders and can be used for cognitive screening among Vietnamese older adults
