Objective To research and design suitable development delay screeningMethods for monitoring 0~1 year old infants within the community,and to provideMethods for early screening and monitoring of children with cerebral palsy.Methods 1)ScreeningMethods design:monthly screening content was designed to cover ages from 1~12 months,and passed through the expert argumentation.2)Study of the reliability,validity and application:Cluster sampling (n=2 711) was performed in infants aged 1~12 months from 6 community health service centers of three city districts.A positive group with positive cases (n=59) and a negative control group with negative cases (n=177) were all performed the test-retest reliability study,and two groups all carried out Denver Developmental Screening Test (DDST) to research criterion-related validity.Developmental condition and muscular tension of the positive referral cases evaluated for application study.3)Statistical analysis was performed by SPSS17.0. Results 1)Reliability:the method provided 100% professional reliability and test-retest reliability.2)Validity:the method possessed criterion-related validity and the positive testing of motor screening were significantly correlated with DDST Results and gross motor developmental delay (r=0.77,P=0.000 respectively).3)Application:screening positive rate was 2.18%.Gross Motor developmental delay was diagnosed in 65.63% of the positive referral cases,but total rates of gross motor developmental delay and edge state was 100%,including 43.75% with abnormal tension of muscle.The diagnosis of cerebral palsy,central coordination disorder and muscular tension dysfunction each included 1 case.Conclusion The screening method is suitable to child health care doctors for motor developmental delay screening among 0~1 year old infants within the community,and with good reliability and validity has value in its application.
