Developmental Assessment Methods in Low- and Middle-Income Contexts
Rigorous developmental assessment methods in diverse cultures and contexts are needed to provide a stronger theoretical and evidence base for community and clinical interventions and policies across the globe. However, cognitive and developmental assessment is challenging in contexts where standardized assessments tools do not exist. Inherent bias can be introduced when transferring such assessments from one context to another. Accurate assessment requires both that the method is valid and that the method is implemented correctly. Implementation is challenging in large trials, in which thousands of children must be assessed in rural settings by data collectors who have no prior experience in developmental assessment. We have developed and published systems for test selection, adaptation, and evaluation to ensure the validity of assessment methods in different contexts, as well as systems for training, implementation, and quality control to administer cognitive and developmental assessments at high quality in large-scale trials. We have also developed several new versions of the Developmental Milestones Checklist, which is a tool designed for developmental assessment in low-resource contexts, and is currently being used to evaluate randomized trials in five countries.
