BACKGROUND: The foundational elements for optimal well-being and health are established during the early stages of life. When progress does not meet expectations, it is necessary to explore possible disorders, health conditions, or other probable factors affecting it. Health professionals in our country must have access to developmental screening instruments that facilitate early detection of these potential risks and delays, thus enabling timely intervention. METHODS: After a pre-selection of the evidence and adequate training of a multi-sectoral panel, a virtual deliberative dialog was held with key stakeholders and decision-makers to determine the most appropriate development screening instrument for the Peruvian context. The evidence was analyzed and discussed in light of the established criteria. In addition, factors pertaining to implementation on a national level were discussed. RESULTS: A set of instruments were obtained and prioritized in the following order: Evaluation of Child Development (EDI, Spanish acronym) ranked first, followed by the Abbreviated Developmental Scale Third Edition (EAD-3, Spanish acronym) and the Ages and Stages Questionnaire (ASQ-3, Spanish acronym), based on the established criteria. The primary components implicated in the execution of this evaluation on a national scale were subsequently identified. CONCLUSIONS: This deliberative dialog has enabled a first approach to the selection of a development screening instrument on the national level, providing valuable information to guide the implementation process.
