Effect of Video Embedded with Hotspots with Dynamic Text on Single-Word Reading by Children with Multiple Disabilities.

Background: The purpose of the study was to evaluate the effects of an intervention using an AAC app programmed with video visual scene displays (VSDs) embedded with hotspots with the Transition to Literacy (T2L) feature on single-word reading.

Method: Three school-aged children with multiple disabilities participated in a multiple baseline across participants design. Four names of characters in favorite movies and shows served as target words for each participant.

Results: All three children demonstrated an increase in accurate identification of target words from baseline to intervention with Tau-U effect sizes for the participants of 0.69, 0.76, and 0.84, all of which were statistically significant (<0.05).

Conclusions: Clinicians can consider including the intervention evaluated in the current study as one component of literacy intervention for school-aged children with multiple disabilities. Future research should further evaluate video VSDs and the T2L feature for use with individuals with multiple disabilities.
