Abstract
Objective—To evaluate the utility of the Bayley Infant Neurodevelopmental Screener (BINS),
standardized in the US, for South American infants, 3 to 24 months of age.
Method—Thirty-five physicians administered the BINS to 2,471 South American infants
recruited during routine well-child visits, 578 (23%) from Brazil and 1,893 (77%) from six other
South American countries. The BINS was translated into Spanish and Portuguese and participating
physicians were trained to administer the BINS. Physician inter-rater agreement with training tapes was 84.4%; test-retest reliability for age item sets ranged from 0.80 to 0.93 (Pearson’s r).
Infants were classified into being at low, moderate, or high risk for developmental delay or
neurological impairment based on their total BINS score. The sample was stratified by infant’s
age, sex and language (Spanish and Portuguese). The BINS scores were compared to the scores of
the US infant sample used to standardize the BINS.
Results—Female infants performed higher than male at 16 to 20 months and 21 to 24 months;
male infant scores were more variable at 5 to 6 months. Scores on only two items were
significantly different between Spanish and Portuguese speaking participants. South American
scores were typically significantly higher than the US sample, and a lower proportion of infants
were classified as being at high risk in the South American sample than in the US standardization
sample.
Conclusion—Overall, the results of this study indicate that the BINS is feasible and appropriate
for neurodevelopmental screening in South America. Further studies are needed to confirm the
BINS utility in South America, including its use with a clinical sample.
