Background and objectives. The Oxford Cognitive Screen (OCS) is a valuable tool for assessing cognitive function, particularly in the context of aphasia and neglect. This study aims to assess the validity and reliability of the Indonesian version of OCS (OCS-INA), which has been adapted and translated following WHO guidelines. Materials and methods. The adaptation and translation process of OCS, in accordance with WHO guidelines, preceded the validity and reliability testing of OCS-INA. The study included participants aged 18 years and above with normal cognitive function, as assessed by the Moca-INA. Data collection took place in social institutions and healthcare facilities that met the specified inclusion criteria. Results. Among the 104 participants meeting the inclusion criteria, a majority were male (51.92%), with ages ranging from 20 to 87 years, and the highest age group being above 60 years (60%). Most participants had a high school education level (35.58%) and were not employed (62.5%). Validity testing, using the Spearman correlation coefficient formula, revealed that the majority of domains had calculated correlation coefficients (r values) exceeding the table values (0.1927). In terms of reliability, the kappa p statistic indicated very good agreement for six examination tasks: semantic (0.874), orientation (0.842), verbal memory (0.822), episodic memory (0.870), and visual field test (1.000). Good agreement scores were obtained for the picture naming test (0.774), sentence reading (0.726), and calculation (0.774). Conclusions. In conclusion, OCS-INA demonstrates both validity and reliability as a screening tool for cognitive impairment. It serves as a valuable complement to existing instruments used for similar purposes.
