Abstract

The Clock Drawing Test is usually used to evaluate prospective patients with cognitive decline as a screening tool. This test is well-known for having rapid administration and flexibility across different cultures. The objective of this study was to explore the psychometric properties of the Clock Drawing Test using the Many-Facet Rasch Measurement approach. We modified the 18-point clock drawing test, specifically adjusting the scale into three levels: poor, fair, and good. This study also involved the Global Deterioration Scale (GDS) as a screening tool to classify participants' cognitive decline status. The Many-Facet Rasch model was applied to analyze 9,045 rating sequences, three clinical psychologist raters, 208 participants, and 15 items. We found the psychometrics information of this modified test was sufficient with the summary of Rasch statistics along with rating scale, item, and rater difficulties analysis. Based on the Wright map, the majority of the items grouped in the middle level, along with the rating scale of this test provided category measure of (-1.73), 0.0, to 1.74. Item 5 “number spacing equal” was the most challenging item for the participants, while item 3, “number all the same (Roman/Arabic)” was the most unchallenging item. Moreover, items 1, 15, and 6 were indicated as misfit items. Rater agreement yielded at 74%. According to ROC analysis, this test effectively predicted participants with mild cognitive impairment and mild dementia based on GDS criteria. Similar studies are recommended to improve the usage of the many facets of Rasch approach in the screening process under many raters' circumstances.
