Objective To explore the applicability of BSID-Ⅲ Cognitive Scale in China to test the reliability and validity of BSID-Ⅲ. Methods BSID-Ⅲ were translated into Chinese,and back translated into English.1 440 infants were randomly selected in Wuxi,Taiyuan and Chenzhou,aged from 16 days to 42 months.Cognitive tests were performed in all infants by BSID-Ⅲ. Results Test-retest reliability was 0.946.The internal consistent reliability,Cronbach coefficient was 0.987.Spearman coefficients of validity was 0.93. Conclusion BSID-Ⅲ Cognitive Scale shows good reliability and validity.It is feasible to assess the cognitive development of infants and toddlers in China.It is practicable and necessary to use it.
