RESUMO
BACKGROUND: Child development assessment tests serve many purposes, including educational placement, identifying cognitive weaknesses, and initiating early interventions. Much of the research associated with developmental testing has been conducted in high-income countries, offering limited guidance on adapting these tests to other settings. OBJECTIVES: As part of the first phase of a study exploring the impact of childhood vaccines on cognition and school attainment, we aimed to assess the feasibility of enrolling children from the community, documenting immunization, and conducting child development assessments for children between 18 months and 8 years of age in a rural setting in Haryana, India. METHODS: To ensure assessments are optimally tailored to the context, child development assessment tests require valid translation and cultural adaptation. This report describes the rigorous seven-step adaptation process we designed for the contextually appropriate adaptation of the following three child development assessment tests: the Bayley Scales of Infant Development-IV, the Stanford Binet Intelligence Scale Fifth Ed. for Early Childhood, and the Wechsler Intelligence Scale for Children IV. RESULTS: This process involved translating tests into the local language, back-translating them for accuracy, adapting them to the rural context via several iterations, and field-testing to refine and validate adaptation quality. CONCLUSIONS: This adaptation process may be beneficial for other researchers involved in adapting child development assessment tests to other settings. Further, this adaptation process may inform other researchers involved in adapting tests for diverse settings.
