Development of the Infant and Toddler Developmental Checklist in China
Objective To raise caregivers'awareness of young children's mental health and childhood development and promote evidence-based parenting practice,we developed the Infant and Toddler Developmental Checklist,and tested the psychometric validity of the checklist to promote early identification of developmental difficulties.Methods By pooling and screening existing developmental milestones and analyzing the infant and toddler developmental data we collected from a multicenter cross-sectional survey,we selected 5 domains and formed the items for the Infant and Toddler Developmental Checklist.We set the passing age of each item as 75% of the children in this age could achieve a certain behavior.The internal consistency coefficient,retest reliability,and tester reliability were used to evaluate the reliability,and the content validity,criterion validity,and structural validity were used to evaluate the validity.Results We developed the Infant and Toddler Developmental Checklist based on the survey data of 144 developmental milestones of 8010 healthy infants and toddlers in 30 districts and counties of 15 provinces in 2020,and with reference to the schedule of primary public health examination.The checklist consists of 5 dimensions:gross motor,fine motor,language,cognition,and social and self-care,covering 8 times visiting from 0 to 3 years old,with a total of 40 items.In terms of reliability,the scale had a retest reliability of 0.990,a tester reliability ICC value of 0.941,and an internal consistency coefficient Cronbach's α coefficient of 0.977,indicating that the stability and internal consistency of the checklist were good.In terms of validity,the content validity index I-CVI was 0.820-1 and S-CVI was 0.929,indicating good content validity.We tested the checklist against Gesell using the non-attainment of two milestones in the matched month age group as the discriminant criterion.The result showed the checklist had a sensitivity of 73.6% and a specificity of 80.7% .Conclusion Through this study we established a psycho-behavioral developmental checklist for infants and toddlers,which is aligned with the primary public health examination schedule for children,with good psychometric properties.Our findings and output provided support for evidence-based parenting and family care and early childhood development.
