Many global settings lack indigenous measures of child development, making the adaptation of available instruments necessary. The aim of this study was to reliably adapt the core subtests of the Wechsler Preschool and Primary Scale of Intelligence-III (WPPSI-III) to assess cognitive abilities in young children in rural Pakistan. A systematic…

There were few differences in functioning change between programs, but applied behavior analysis (ABA) was most…
