Which screening tool is cited as an example for developmental surveillance in infants?

• A. Denver Developmental Screening Test
• B. Bayley Scales of Infant Development
• C. ASQ
• D. Peabody

Answer: (C)

Developmental surveillance relies on ongoing monitoring of a child’s development across visits, using tools that can be repeated over time to catch emerging concerns. The Ages and Stages Questionnaires fits this purpose well because it is a parent-completed screening tool designed for serial use in infants, quickly covering multiple domains (communication, motor skills, problem solving, personal-social) and flagging areas that may need further evaluation. Its quick format and accessibility for families make it practical for regular use during well-child visits, helping clinicians track progress and identify children who may benefit from deeper assessment. The other options are more comprehensive assessments or longer, resource-intensive tools that aren’t as well suited for routine surveillance in primary care.
