Purpose: The pediatric and adult versions of the SCAN-3 test (Keith, 2009a, 2009b) are widely used to screen and diagnose auditory processing disorders. According to the instruction manual, the test administration is flexible in that it may be administered through an audiometer at 50 dB HL or a portable CD player at the patient or administrator's most comfortable listening level (MCL). Because MCL may vary across individuals, even in those with normal hearing sensitivity, this study explored whether the presentation level affected scores on the SCAN-3 for both pediatric and adult populations...

Purpose: Effective clinical communication is pivotal to the provision of quality hearing health care. To date, audiology students reportedly felt ill-prepared when counseling patients about their hearing impairment, yet there is a paucity of studies exploring how clinical communication is taught and learned in audiology programs. Thus, the aims of the study were (a) to explore final year audiology students' perspectives of their own clinical communication skills during an in-house university clinical placement and (b) to explore students' perceptions of their clinical communication education...

Purpose: The aim of this study was to determine if there are factors that can predict whether a child with hearing loss will also have vestibular loss. Method: A retrospective chart review was completed on 186 children with hearing loss seen at Boys Town National Research Hospital for vestibular testing from 1999 to 2015 through neurosensory genetics clinic or cochlear implant candidacy. Each child's medical chart was reviewed to obtain the following data: vestibular loss severity (classified as normal, bilateral, or mild to moderate), degree of hearing loss (bilateral pure-tone average [PTA]), imaging abnormalities (classified as "normal" or "abnormal"), parental concerns for gross motor delay (classified as "yes, there is concern" or "no, there is not a concern"), parent report of age when their child sat (months) and walked independently (months), comorbidities (classified as "yes" if there were 1 or more comorbidities or "no" if there were no comorbidities), and score on the Developmental Profile-3...

Purpose: The Chinese Sound Test (Hung, Lin, Tsai, & Lee, 2016) has been recently developed as a modified version of the Ling Six-Sound Test (Ling, 2012). By incorporating Chinese speech sounds, this test should be able to estimate whether the listener can hear across the Chinese speech spectrum. To establish the clinical validity of the test, this study examined the relationship between the aided audiometric thresholds and the distance thresholds. Method: Sixty children with bilateral hearing aids were recruited...
