The Survey of Well-being of Young Children (SWYC)™ is a tool that can be used for general developmental surveillance and screening of young children in the pediatric primary care context. This tool may be aid in identifying a young child’s risk of developmental-behavioral issues and in informing interventions through conversations between the child’s caregiver and provider.
- Developmental milestones
- Behavioral/emotional development
- Family risk factors
- Optional: Autism specific screening
Administration Format: parent/caregiver self-report
Administration Time: ~15 minutes
Reliability and Validity (Perrin 2016, User Manual): through initial reliability and validity research, the SWYC was found to be comparable to older and familiar developmental screening instruments.
- Milestones: concurrent validity testing suggested SWYC milestone forms had moderate to large correlations with Ages & States Questionnaire, 3rd Edition (ASQ-3) (0.40 – 0.70), excluding the 2 month form. Accurately detected parent report of developmental delays comparable to using other screening instruments. The overall sensitivity was 76% and specificity was 77%.
- Behavioral Development (baby): factor analysis identified 3 BPSC subscales (irritability, inflexibility, difficulty with routines) based on child’s behavior and reliability testing suggested adequate Cronbach’s alpha across subscales, excluding irritability (<0.70). Test-retest reliability was also adequate across the three scales (0.70 for “Irritability,” 0.81 for “Inflexibility,” and 0.78 for “Difficulty with Routines”). Correlation was mild to moderate for subscales across other metrics (ASQ:SE, PHQ-2, PSI-SF).
- Behavioral Development (preschool): factor analysis identified one bifactor model and thus a single PPSC score. Reliability testing suggested adequate Cronbach’s alpha across samples (86 – 0.92). Test-retest reliability was also adequate, with an interclass correlation coefficient of 0.75. PPSC scores were compared across other metrics (ASQ:SE, CBCL) and consistently found high sensitivity and specificity.
- Autism Screening: adequate internal reliability was found with a Cronbach’s alpha ranging from 0.83 – 0.86, SWYC sensitivity in primary care contexts (89%) was significantly higher than the M-CHAT’s (71%), and somewhat higher in referral (83% versus 94%).
- Family Risk: these questions were not separately validated as part of the SWYC.
