Description

INTRODUCTION
• Empirical evidence demonstrates benefits of AAC communication for individuals with intellectual and developmental disabilities
• However, trends of refusal and abandonment of AAC systems by these populations have been documented
• Diffusion of Innovations by Everett Rogers introduces a framework conceptualizing why some innovations encounter uptake while others suffer abandonment or refusal
• The framework includes four factors that are cited as contributing to uptake: the innovation, communication channels, time, and the social system
• This study examines the characteristics important to the innovation factor in order to provide data specific to the innovation of AAC systems
• These characteristics include relative advantage, compatibility, complexity, trialability, observability, and re-invention

RESEARCH QUESTIONS
• What is the current literature on AAC abandonment and refusal?
• How do the addressed factors of refusal/abandonment in the literature correlate to Rogers’s Diffusion of Innovation?
