Psychometric Evaluation of the Dementia Stigma Measure with Vietnamese Adults: An Exploratory and Confirmatory Factor Analysis Approach

ObjectivesThis study aims to conduct a psychometric evaluation of the Dementia Stigma Measure (DSM) with Vietnamese adults in two different studies.MethodsIn Study 1, exploratory factor analysis (EFA) of the original 11-item scale was conducted on a sample of 325 Vietnamese community-dwelling adults in a Northern area. In Study 2 with 407 adults living in Southern Vietnam, confirmatory factor analysis (CFA) was conducted using structural equation modeling to test the validity and reliability of the modified DSM with retained factors and items found in Study 1.ResultsThe EFA results in Study 1 suggested five retained items loaded on one factor. The CFA with another sample with close demographic characteristics but in a different region of Vietnam showed good model fit indices.ConclusionsBoth studies supported the one-factor structure of the modified five-item DSM, a valid and reliable brief measure of public stigma for Vietnamese community dwellers.
