Development and Validation of a New Lucknow Development Screen for Indian Children Aged 6 Months to 2 Years

Abstract

A chart was prepared using selected milestones from Baroda norms of Bayley Scales of Infant Development and Gesell’s schedules on y-axis and age in months on x-axis. A child failing to achieve any milestone to the left of the chronological age was screen positive. Interrater and test-retest reliability were calculated. For validation, the screen was administered to mothers of 142 children aged 6 to 24 months attending Pediatric Outpatients or Neurology Clinic of CSM Medical University, Lucknow, India. Acutely ill children were excluded. A full Developmental Assessment Scale for Indian infants was then done on the same children. Sensitivity and specificity were 95.9% and 73.1%, respectively. It is concluded that Lucknow Development Screen can be effectively used for screening in the community.
