description: <b>Aim:</b> This study aimed at improving the utility of the fine motor subscale of the comprehensive developmental inventory for infants and toddlers (CDIIT) by developing a computerized adaptive test of fine motor skills. <b>Methods:</b> We built an item bank for the computerized adaptive test of fine motor skills using the fine motor subscale of the CDIIT items fitting the Rasch model. We also examined the psychometric properties and efficiency of the computerized adaptive test of fine motor skills with simulated computerized adaptive tests. <b>Results and conclusions:</b> Data from 1742 children with suspected developmental delays were retrieved. The mean scores of the fine motor subscale of the CDIIT increased along with age groups (mean scores = 1.36–36.97). The computerized adaptive test of fine motor skills contains 31 items meeting the Rasch model’s assumptions (infit mean square = 0.57–1.21, outfit mean square = 0.11–1.17). For children of 6–71 months, the computerized adaptive test of fine motor skills had high Rasch person reliability (average reliability &gt;0.90), high concurrent validity (rs = 0.67–0.99), adequate to excellent diagnostic accuracy (area under receiver operating characteristic = 0.71–1.00), and large responsiveness (effect size = 1.05–3.93). The computerized adaptive test of fine motor skills used 48–84% fewer items than the fine motor subscale of the CDIIT. The computerized adaptive test of fine motor skills used fewer items for assessment but was as reliable and valid as the fine motor subscale of the CDIIT. Implications for RehabilitationWe developed a computerized adaptive test based on the comprehensive developmental inventory for infants and toddlers (CDIIT) for assessing fine motor skills.The computerized adaptive test has been shown to be efficient because it uses fewer items than the original measure and automatically presents the results right after the test is completed.The computerized adaptive test is as reliable and valid as the CDIIT.
