OBJECTIVE: Validate a tool to determine neurodevelopmental impairments (NDIs) in >2- to 5-year-old children in a country with limited child development expertise. METHODS: Rapid Neurodevelopmental Assessment (RNDA) is a tool designed to detect functional status and NDIs across multiple neurodevelopmental domains. Validity was determined in 77 children enrolled by door-to-door sampling in Dhaka and who were administered the RNDA by 1 of 6 testers (4 developmental therapists, 2 special education teachers) and simultaneously administered a test of adaptive behavior (AB; Independent Behavior Assessment Scale) and intelligence quotient (IQ) tests (Bayley Scales of Infant Development II, Stanford Binet Intelligence Scale, Wechsler Preschool and Primary Scales of Intelligence) by psychologists. RESULTS: Interrater reliability ranged from good to excellent. There were significant differences in AB in mean percentile scores on the Independent Behavior Assessment Scale for motor (P = .0001), socialization (P = .001), communication (P = .001), and full-scale (P = .001) scores in children with >= 1 NDI ("any NDI") versus no NDI. Significant differences in those with versus those without "any NDI" were found on IQ scores. Sensitivity and specificity for "significant difficulties" (defined as AB z-scores < -2 SDs and/or IQ < 70) and "mild difficulties included" (AB z-scores < -1SD and/or IQ <85) were 90% and 60% and 80% and 76%, respectively. CONCLUSIONS: The RNDA validity results are promising for use by child care professionals in field and clinical settings, but the tool needs further replication and refinement for assessment of specific impairments of vision, hearing, and seizures.
