Validation of parental screening tool S-PMV11: Convergent validity with Bayley-III in assessing developmental...

With the increasing use of developmental screening tools, there is a growing need to validate parental screening methods for the early detection of developmental difficulties in children, regarding their psychometric properties.

This study evaluates the convergent validity of the S-PMV11 parental screening tool by comparing its outcomes with the Bayley Scales of Infant and Toddler Development (Bayley-III), the gold standard for direct assessment.

We analyzed data from 30 children and found significant correlations between S-PMV11 scores and Bayley-III assessments across cognitive, language, and motor skill domains. Notably, expressive communication showed the strongest correlation, indicating that parents are reliable assessors of developmental risks.

Despite limitations related to potential overestimation in Bayley-III, our findings support the S-PMV11 as a valid tool for early identification of developmental challenges, enhancing early intervention strategies in pediatric healthcare.
