This SIG 17 activity focuses on the prevalence and identification of communication disorders in Japan, Guatemala, and global contexts. The first study conducted in Japan examines the prediction of special educational needs in children who stutter using a screening test for three neurodevelopmental disorders (specific learning disorder, attention-deficit/hyperactivity disorder, and autism spectrum disorder). The second study explores clinical practices for speech sound disorders in Guatemala, particularly the use of nonspeech oral motor exercises. Last, the third study provides insights into the frequency of aphasia worldwide. By examining these diverse contexts, participants will gain a comprehensive understanding of communication disorders and their identification in different regions.

Learning Outcomes
You will be able to:

• summarize clinical practices for speech sound disorders in Guatemala, including the use of nonspeech oral motor exercises
• describe the global prevalence of aphasia after stroke, examining rates across various countries and income levels
• explain the importance of cultural and contextual factors in the prevalence and identification of communication disorders in diverse populations

Assessment Type
Self-assessment—Think about what you learned and report on the Completion Form how you will use your new knowledge.
