| Summary | Comments about sensitivity to change | This is a screening measure; sensitivity to change is likely to be limited |
| General remarks | The SWYC is a free, brief, accessible and comprehensive screener for early developmental concerns. Qualitiative research with AIAN communities (Whitesell et al, 2015; https://www.ncbi.nlm.nih.gov/pubmed/26312600) indicated that it is likely to be a good fit in general, but research is needed to understand its reliability and validity in this population. |
