Abstract
Background: ASDs with lower functioning have always been eliminated from using high-tech AAC based on myths that are too high for their abilities. The current study examined the role of IQ on using the augmentative and alternative communication system (AAC) that runs on an iPod touch to improve spontaneous communication of low functioning ASDs children in their daily communication needs. Material/Methods: 22 subjects, diagnosed with an ASD, were randomly assigned to receive a standardized AAC and were divided to three groups based on their IQ level; the AAC sessions were for a period of 8 weeks. Measures included changes in professionally completed Pervasive Developmental Disorder Behaviour Intervention (PDDBI), and Aberrant Behaviour Checklist (ABC). Results: Results indicated no significant difference between the three groups in terms of ABC and PDDBI, the three groups gained the same benefits from the high - tech AAC. Conclusions: ASDs with lower functioning could gain benefits from high-tech AAC with the same rate as kids with high functioning. (C) 2015 The Authors. Published Elsevier Ltd.
