AB  - BACKGROUND: The Bayley Scales of Infant and Toddler Development is widely used 
      worldwide. The objective of the current study was to measure the stability of the 
      Bayley Scales during early childhood and its relationship with intellectual 
      abilities at four years in young Nepalese children. METHODS: In a prospective 
      cohort we used the Bayley 3rd edition to measure early child development in 529 
      Nepalese children at 6-11, 18-23 and 30-35 months. At four years, we used the 
      Wechsler Preschool and Primary Scale of Intelligence (WPPSI) to measure 
      intellectual abilities. We expressed the stability of the Bayley scores by 
      intraclass correlation coefficients (ICCs) and concordance correlation 
      coefficients (CCCs). The relationship between the Bayley scores and the WPPSI 
      full-scale IQ (FSIQ) at four years was examined in regression models. RESULTS: 
      The ICCs between the Bayley scores across timepoints were 0.01 (95 % CI -0.06, 
      0.04), 0.19 (95 % CI 0.15, 0.26) and 0.22 (95 % CI 0.17, 0.28) for the Cognitive, 
      Language and Motor composite scores. The CCC for the composite scores ranged from 
      0.05 to 0.20 between 6 and 11 and 30-35 months and from 0.20 to 0.36 between 18 
      and 23 and 30-35 months. The Bayley scores at 6-11, 18-23 and 30-35 months 
      explained 3 %, 20 % and 36 % of the variation of the FSIQ. CONCLUSION: The 
      stability of the Bayley scales is poor in early childhood, and its relationship 
      with future intellectual abilities is poor in infancy but improves slightly with 
      age in early childhood. Findings from this large community-based cohort of 
      healthy at-risk children are relevant when measuring early child development 
      worldwide.
