ABSTRACT
AAC efficacy study is important to establish best practices, maximize outcomes, ensure accountability, and in some cases justify cost. Conducting efficacy research in the research of AAC, however, faces significant challenges due to the heterogeneity of the population of people who use AAC, the complexity of AAC systems and interventions. In this paper, discussions are organized around the following issues: (1) theoretical background of AAC efficacy, (2) participant selection, (3) intervention goal (dependent variable) and intervention methods (independent variable), (4) experimental design, generalization and maintenance, and (5) comparative efficacy study. Issues about the treatment integrity and social validation and methods to ensure those are also discussed in relation to both dependent and independent variables.
