Development and diagnostic accuracy of dyslexia early identification flowchart for pediatric practice

This study developed and evaluated the Rapid Automatized naming, Phonological Awareness, and Letter Identification (RAPALI) flowchart for early dyslexia identification in pediatric settings. Using early literacy skills at kindergarten level from the Thai emergent literacy for predicting dyslexia longitudinal study, the RAPALI flowchart effectively identified dyslexia risk at grade 3 level, boasting an AUC of 0.71, a sensitivity of 95.5%, and a negative predictive value of 99.1%. RAPALI demonstrated acceptable specificity and positive predictive value. The user-friendly flowchart aids early identification, interventions, and preventive measures for dyslexia, benefiting affected children and their families. However, further validation and adaptation are needed.
