Psychometric evaluation of the Brief Cognitive Screening Battery: Indonesian version

Abstract

Dementia is a significant public health challenge, particularly in low-and middle-income countries such as Indonesia, where underdiagnosis is common. Objective: To investigate the psychometric properties of the Brief Cognitive Screening Battery – Indonesian Version (BCSB-INA), a culturally-adapted tool aimed at improving the early detection of dementia. Methods: The tool was tested on a sample of 140 older adults, covering various cognitive domains through multiple subscales. Data were analyzed using bootstrap resampling, Kaiser-Meyer-Olkin (KMO) test, Confirmatory Factor Analysis (CFA), and reliability assessments such as Cronbach’s Alpha. Results: The overall reliability, measured by Cronbach’s Alpha, was high (α=0.968). The KMO test yielded a value of 0.889, indicating sample adequacy for factor analysis. The CFA indicated that most dimensions achieved satisfactory validity, with the majority of items demonstrating acceptable factor loadings. Conclusions: BCSB-INA has demonstrated good reliability and validity throughout its dimensions, suggesting its applicability for use in cognitive assessments in the Indonesian context.
