A personal digital assistant for improving independent transitioning in adolescents with high-functioning autism spectrum disorder

Objective: This study evaluated the effectiveness of a personal digital assistant (PDA) on independent transitioning between activities in a day treatment centre for youth with high-functioning ASD. Methods: Within a multiple baseline design across four participants, data were collected on participant's transitioning and staff's prompting behaviour. Intervention by staff consisted of one technical instruction session on use of the PDA and non-specific instruction following incorrect transitions while not using the PDA, in the natural setting. Results: Analysis revealed a significant increase in percentage independent daily transitions, which resulted from the independent use of the PDA. The change in staff's prompt use during intervention was mainly the result of a significant decrease in the use of non-specific prompts in correcting participant's transition behaviour. Conclusion: A brief intervention was effective in improving independent transitioning using a PDA. Findings are evaluated in light of their clinical implications and suggestions for future research are discussed.
