| Objective:To assess the application of Cognitive sub-tests of Bay ley scales of Infant and Toddler Development III and exam the influencing factors of normal infant cognitive development, to provide valid tools and exact data.Methods:According to the principle of informed consent,480infants were randomly selected in Wuxi, Taiyuan and Chenzhou respectively, aged from17days to42months and10days and the girl to boy ratio of1:1. Cognitive tests were performed in all infants and the related factors were investigated with the self-designed questionnaire.Results:1The sample size:1444age appropriate infants were collected in the study, including722boys and722girls.2Application:Test-retest reliability is0.961、0.899、0.963in Wuxi, Taiyuan, and Chenzhou, average test-retest reliability is0.946. Cronbach coefficient is0.986、0.987、0.987in Wuxi, Taiyuan, and Chenzhou, and the average Cronbach coefficient is0.987.3Cognitive development in girl group and boy group:There were no significant difference between girl group and boy group in in Wuxi, Taiyuan, and Chenzhou respectively(P>0.05). Significant difference can be found in the total sample(P <0.01).4Cognitive development in the three setting:Infants in Wuxi scored more highly than that in Taiyuan and Chenzhou(P<0.01).5The difference of cognitive developmental quotient was not found among groups of delivery mode and maternal age at childbirth(P>0.05).6The difference of cognitive developmental quotient was not found among the three groups of Kaup index in the study(P>0.05).7There are no significant difference between groups of number of children in Wuxi and Taiyuan(P>0.05). But the difference is significant in Chenzhou and in the total sample(P<0.05). The scores of the infants in higher education group (mother and father) were significantly higher than that in Primary and secondary group (P<0.01). There was significant difference among the occupation(mother and father) groups(P<0.01). The infants in specialty technical staff group (mother and father) scored significantly higher than that in the officer group and other service group.8.Of the factors, stepwise multiple linear regression showed that parental occupation and paternal education had the most important effect on children’s cognitive development..Conclusion:Bayley III Cognitive Scale shows good reliability. It is feasible to assess the development of infants and toddlers in china. The parents with higher education level have a good family environment for the cognitive development in normal children. |
