Abstract
ABSTRACT Purpose: to develop and validate the content of the communication screening instrument for children aged 0 to 36 months. Methods: an instrument comprising nine categories organized into five domains, according to developmental milestones per age group. The research was conducted in two stages. The first included item construction and theoretical content validation by seven judges with expertise in child language. The second included the empirical validation by the target population, in which three speech-language-hearing pathologists applied the instrument to 30 parents in a school in Recife, PE, Brazil. First-stage data analysis focused primarily on verifying agreement between the judges. In the second stage, the examiners suggested adjusting some items, and the children's performances were stratified. Results: a high level of interjudge agreement was observed in the first stage (CVI > 0.90). In the second stage, the performances stratified into quartiles confirmed the instrument’s feasibility for discriminating normally developing children from those at risk of a communication disorder or needing attention. Conclusion: the process ensured the instrument's content validity, with further validation steps being recommended.
