Developmental delays and autism: Screening and surveillance.

Abstract

Screening and surveillance are crucial components to the early detection of developmental disorders in children, which enables early interventions that provide the best chances for improved outcomes. Identifying a developmental disorder is the initial step in evaluating the disorder. Surveillance is a flexible, continuous, longitudinal process aimed at identifying concerns, and it should be performed at every well-child visit. Screening involves administering a brief, standardized tool normalized for specific ages and stages of development to identify any developmental delays or specific concerns such as autism. Screening is recommended at every office visit and whenever a parent expresses a concern. Two general types of screening tests are available: problem-specific screening and broadband developmental screening. For each type, there are multiple different tests available that can be administered by a parent or a health care provider. Factors to consider in the test selection are the age range for which it is intended, time it takes to complete and score, cost, whether the test is paper-based or electronic, and the language availability.
