dc.description.abstract In low- and middle-income countries measuring early childhood development with standard tests in large scale surveys and evaluations is difficult and expensive. Therefore, screeners and caregiver reports, of unknown validity in these circumstances, are frequently used. We examine the feasibility, reliability, and concurrent validity of short tests currently used including three multi-dimensional screeners—the Ages and Stages Questionnaires (ASQ-3), the Denver Developmental Screening Test (Denver-II), the Battelle Developmental Inventory screener (BDI-2)—and two single-domain tests—the MacArthur-Bates Short-Forms (SFI and SFII) and the WHO Motor Milestones (WHO-Motor)—in 1,311 children 6-42 months in Bogota, Colombia. We compare scores on these short tests to those on the Bayley Scales of Infant and Toddler Development (Bayley-III). The Bayley-III, our ‘gold standard’, was given at a center by psychologists; whereas the short tests were administered at home by fieldworkers, as in a survey setting. Concurrent validity with the Bayley-III is low below 19 months for the cognitive, language, and fine motor scales but increases with age, becoming moderate-to-high over 30 months. In contrast, gross motor scales’ concurrence was high under 19 months and then decreased. Of the single-domain tests, the WHO-Motor had high validity with gross motor under 16 months, and the SF expressive scales showed moderate correlations with language under 30 months. Overall, the Denver-II was the most feasible and valid multi-dimensional test and the ASQ-3 performed poorly under 31 months. Results do not vary by household socio-economic status. Predictive validity investigation is needed to further guide the choice of instruments for large scale studies. en
