BEHAVIORAL

Written language intervention

Young adults with Intellectual and Developmental Disabilities (IDD) are taught reading comprehension strategies in three phases (before, during, after) using a graphic organizer as visual support. At the beginning of each phase, the interventionist: (a) defines the strategies, (b) describes and models how to use the strategies, and (c) answers questions about the strategies. Then the participant practices the strategies during 45-min sessions, two times per week, over 3 months. Each session follows the teach-model-coach-review format, the interventionist: (a) reviews the strategies (5 min), (b) models the strategies using a think-aloud (10 min), (c) prompts the participant to practice the strategies with support (15 min), (d) prompts the participant to use a think-aloud to practice the strategies independently using a functional literacy text (10 min), and (e) reviews and summarizes the session (review; 5 min).
