    Abstract:
    Purpose The objective of this study was to investigate the relationship between 2 variables that influence augmentative and alternative communication (AAC) use, caregiver operational competency (i.e., the ability to navigate, customize, and program the device), and AAC system buy-in (i.e., understanding that the device acts as the child's voice and should be treated as an extension of his or her physical body), to determine if there was a relationship between these variables and device use at home and at school in school-age children with autism who use AAC. Method The device use of 29 school-age children ( M age = 7.82 years) with an educational diagnosis of autism who use AAC was tracked using the logging feature on the participants' AAC devices. Participants' parents ( n = 29) and teachers ( n = 14, some teachers reported on multiple students) completed a questionnaire assessing caregiver operational competency and AAC system buy-in. Minutes of data use were extracted from each participant's AAC device ( Cross & Segalman, 2016 ) and averaged across three randomly selected dates. Results The parents and teachers reported high rates of operational competency and buy-in. However, only 10 of the children used their devices at home during the weekends. Despite high rates of parent- and teacher-reported operational competency, participants did not use their devices at high rates. Conclusion Speech-language pathologists may also need to focus on other aspects of parent and teacher training, such as creating communication opportunities for students who use AAC to increase device use at home and at school.
