“…The 2013 GRI count reported an incidence of 3% of ASD in the DHH student population [4] and similarly, other researchers have reported a higher incidence of ASD in the DHH population than is found in the population of hearing students [8,25,88] but there is not consensus in the literature of whether prevalence is actually higher [30]. However, it is also thought that the diagnosis of ASD is often overlooked in the population of students who are DHH [25,88] and diagnosis is complicated by the lack of standardized assessment instruments for ASD that are appropriate for the DHH population, difficulties in audiological assessment, overlapping characteristics of ASD and DHH, and diagnostic overshadowing [25,27,28,30,40,88]. The literature base in DHH-ASD is limited but includes identification and assessment [28,30,31,89], social interaction and behavior [90][91][92][93], speech development [13,32,41], sign language [94][95][96], AAC [97], family supports [98,99], and teacher perceptions [34,100].…”
