| Summary: | <h4>Background</h4> <p>Oxford Cognitive Screen is designed for assessing cognitive functions of poststroke patients.This study was aimed to assess the psychometric properties of the Chinese (Putonghua) version of theOxford Cognitive Screen-Putonghua (OCS-P) for use among poststroke patientswithout neglect.</p> <h4>Methods</h4> <p>Expert reviewpanel evaluated content validity of theChinese-translated items. After pilot tested the translated items, the patients and healthy participants completed the OCS-P as well as theMontreal Cognitive Assessment (MoCA-ChiB) andGoldenberg’s test.Agroup of patients completedOCS-P for the second timewithin seven days.Data analyses included confirmatory factor analysis, item difficulty and item-total correlation, inter- and intrarater reliability, internal consistency, and between-group discrimination.</p> <h4>Results</h4> <p>One hundred patients and 120 younger (𝑛 = 60) or older (𝑛 = 60) healthy participants completed all the tests. Modifications were required for items in the “Picture Naming”, “Orientation”, and “Sentence Reading” subscales.Confirmatory factor analysis revealed a three-factor structure for theOCS-P subscales.The internal consistency coefficients for the three identified test dimensions were 0.30 to 0.52 (Cronbach’s alpha). Construct validity coefficients between the OCS-P and MoCA-ChiB subscales were 0.45 < 𝑟 < 0.79 (𝑝 < 0.001) and the “Praxis” subscale of OCS-P and Goldenberg’s test was 𝑟 = 0.72 (𝑝 < 0.001). The interrater reliability coefficients for the subscales were in general higher than the intrarater reliability coefficients.The “Picture Naming” and “Numerical Cognition” subscales were the most significant (𝑝 = 0.003) for differentiating patient participants from their older healthy counterpart.</p> <h4>Conclusion</h4> <p>This study generated satisfactory evidence on the content validity, substantive validity, construct validity, inter- and intrarater reliability, and known-group discrimination of theOCS-P.They support its application among poststroke patients who speak Putonghua. Future studies could review the existing five-dimension domains for improving its structural validity and internal consistency as well as generate evidence of the OCS-P for use among the poststroke patients with neglect.</p>
