The Survey for the Well-Being of Young Children (SWYC) is a screening tool typically completed by parents during pediatric visits for children under five and a half years of age. The SWYC consists of several different scales that measure motor, language, social, cognitive, and social-emotional development. The questionnaires assess three domains: developmental, emotional/behavioral, and family context. There are five parts to the SWYC including the Developmental Milestones checklist, Parent’s Observations of Social Interactions (POSI), Baby Pediatric Symptom Checklist (BPSC), Preschool Pediatric Symptom Checklist (PPSC), parent’s concerns, and family questions. The SWYC takes 15 minutes to complete.
SWYC results predict the performance on early literacy examinations in kindergarten, demonstrating that identifying children who need intervention before kindergarten can improve school readiness. The BPSC, the PPSC, and the POSI demonstrate moderate to strong internal consistency reliability. The POSI has acceptable sensitivity in identifying the risk for autism in children at least to age 48 months. The Developmental Milestones checklist, the BPSC, and the PPSC are moderately accurate at correctly identifying children at risk for developmental delays and low to moderate accuracy at identifying children who are not at risk for delays.
