The Survey of Well-being of Young Children

The Survey of Well-being of Young Children (SWYC)™ is a freely-available, comprehensive screening instrument for children under 5 years of age. The SWYC was written to be simple to answer, short, and easy to read. The entire instrument requires 15 minutes or less to complete and is straightforward to score and interpret. The SWYC is approved by MassHealth for compliance with the Children's Behavioral Health Initiative screening guidelines.

Recognized by the American Academy of Pediatrics

According to the AAP policy statement on developmental surveillance and screening, “it is appropriate to perform additional developmental screens using validated tests. These screenings should be recognized separately, with appropriate coding, billing, and payment and with the additional cost acknowledged in capitated expectation.” The policy statement provides “a list of developmental screening tests and their psychometric testing properties,” noting that “these screening tests, which are focused on parent-completed tools, have acceptable psychometric properties.” The table includes the SWYC Milestones under “general developmental screening tests”, the BPSC and PPSC under “behavioural screening tests”, and the POSI under “Autism Screening: Promising Tests”.

Utilizing the SWYC in your practice

The current version of the SWYC has been extensively researched, and further research is ongoing. In addition, the current version is widely disseminated. For these reasons, any changes to the components of the SWYC are strongly discouraged. In unusual circumstances, requests for exceptions will be considered by the authors (

On the other hand, translations of any and all components of the SWYC are strongly encouraged. The process we recommend for translations is described in chapter 4 of the SWYC Manual, and final versions should be made available to be posted on the website.
