Social inequalities in maternal opinion of child development in southern Brazil.

Aims And Methods: Concurrent validity of maternal opinion of child development was estimated in a cross-sectional, population-based survey of 6-59-mo children (n=3025), using a standard measure devised from the Denver Developmental Screening Test.

Results: Sensitivity, specificity and negative predictive value increased with maternal education and family income. Positive predictive value was higher in low-income families and children with impairments, low birthweight and long hospital stays.
