[Study of the reliability of a parenteral questionnaire used in a pediatric follow-up of 18-month-old children].

: We are conducting a validation study of questionnaire to the parents according to the Griffiths Mental Developmental Scale, used in pediatric follow-up of obstetric studies among the Italian population. The questionnaire concerns the child's gross and fine motor and language development, swallowing, respiratory, hearing and vision problems, and hospital admissions within the first 18 months of life. The purpose of this study is to examine the degree of agreement between parental and professional assessment of normal and high-risk infants development at 18 months of life.
