Validation of a rapid neurodevelopmental assessment tool for 10- to 16-year-old young adolescents in Bangladesh.

Objective To validate a Rapid Neurodevelopmental Assessment (RNDA) tool for use by child health professionals to determine neurodevelopmental impairments (NDIs) in young adolescents aged 10-16 years in Bangladesh. Study design In a convenience sample of community children ( n = 47), inter-rater reliability was determined between four testers, and concurrent validity was determined by simultaneous administration of an intelligence quotient (IQ) test (Wechsler Intelligence Scale for Children, Revised) by a child psychologist. Results Inter-rater reliability was excellent between the testers on the 47 children administered the RNDA (kappa = 1.00). Significantly lower IQ scores were obtained in those identified with 'any ( >1) NDI' ( n = 34) compared with those with no NDI ( n = 13) on Verbal IQ ( P-value < 0.0001), Performance IQ ( P-value < 0.0001) and Full-scale IQ ( P-value < 0.0001) scores on the Wechsler Intelligence Scale for Children, Revised. Conclusion The RNDA shows promise as a tool for use by child health professionals for identifying NDIs in young adolescents aged 10-16 years. A larger study sample is needed to determine its usefulness for identification of some impairments not found in the study population, i.e. gross motor, fine motor, hearing and seizures.
