Trial Outcomes & Findings for Written Language Intervention for Adults With Intellectual and Developmental Disabilities (NCT NCT05851937)

NCT ID: NCT05851937

Last Updated: 2026-01-14

Results Overview

Total number of different reading comprehension strategies used correctly. A blank version of the FRAME intervention graphic organizer including only the picture icons of the reading comprehension strategies was displayed alongside a functional text stimulus (e.g., text messages, e-mails) that was designed to closely reflect participants' daily written communications. the examiner prompted the participant to begin reading the functional text. Each think-aloud was scored for the participants' accurate use of reading comprehension strategies. A percent accuracy score was calculated based on (a) the total number of strategies implemented correctly (out of nine; excluding Strategy 4 \[read text aloud\] because all participants were expected to read the text) and (b) implementing the strategies at the appropriate time (before, during, after reading) to earn up to three additional points (max score = 12). Higher scores reflect better performance.

Written Language Intervention
Participants will receive 3 months of weekly written language intervention sessions via telepractice. Participants will be assessed at three time points to monitor outcomes. 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).

SECONDARY outcome

Timeframe: 3 months after start of intervention

Percentage of multiple choice comprehension questions answered correctly. The interventionist prompted the participant to read a functional text stimulus aloud and then prompted the participant to answer five (two literal, three inferential) multiple-choice questions that were read aloud by the interventionist. This task was repeated across a total of six functional literacy stimuli, two in each of the following domains-employment, independent living, and social. A percent accuracy score was calculated for each of the functional literacy stimuli, and a total average score was reported across all functional literacy stimuli. Higher scores reflect better performance.

SECONDARY outcome

Timeframe: 3 months after start of intervention

Respond to functional text using spoken modality. The assessor displayed a functional text and prompted the participant to help them verbally respond to the functional text sample. All the functional texts utilized in the spoken language measure requested three pieces of information (e.g., state your name, e-mail, T-shirt size) and thus were scored using a 4-point (0-3) rubric rating with 1 point awarded for each piece of information provided. Higher scores reflect better performance. This task was repeated across a total of six functional literacy stimuli, two in each domain; an average score was reported.

SECONDARY outcome

Verbal summary of functional text. The assessor displayed a functional text and prompted the participant to read the text and then provide a summary of all the important information. Summaries were scored using a rubric that evaluated content, accuracy, paraphrasing, and organization each using a 4-point (0-3) scale. Higher scores reflect higher performance.
