Purpose: To evaluate how screening tools Parents’ Evaluation of Developmental Status (PEDS) and Parents’ Evaluation of Developmental Status: Developmental Milestone (PEDS:DM) compare with diagnostic tool Bayley Scales of Infant and Toddler Development, 3rd Edition (BSID).
Method: Children from the Growing Up In Singapore Towards Health Outcomes cohort who completed 18 and 24 month(m) PEDS, PEDS:DM and 24m BSID in English were included. Preterm births were excluded. Delay in developmental domain is defined as parental concern for PEDS; failing domain-specific question for PEDS:DM; domain score of ≤1 standard deviation (SD) for BSID. Predictive validity of 18m PEDS and PEDS:DM with 24m BSID and concurrent validity and accuracy of 24m PEDS and PEDS:DM with 24m BSID were compared using Cohen’s Kappa (κ) and κ p-value.
Conclusion: PEDS and PEDS:DM have fair to moderate predictive validity, concurrent validity and high NPV in language domain. Alternative screening tools should be considered for non-language domains in our population.
