This was a pioneer study whose purpose was to investigate the auditory processing abilities of inmates residing in a medium security prison using the SCAN-A: A Test for Auditory Processing Disorders in Adolescents and Adults. Subject selection criteria was met if the subject passed an otoscopic examination and a pure tone threshold hearing screening. Forty-one inmates, with a mean age of 33.1, met the selection criteria. The SCAN-A was administered according to the examiner manual specifications. Responses were recorded for later quantitative analysis. Scores for the auditory figure-ground, competing words, and competing sentences subtests, and the total test were significantly lower than scores for the nonnative sample. Subjects were judged to have "questionable to disordered" central auditory processing abilities. Findings should be interpreted cautiously because of questions raised regarding the structure of the SCAN-A. Further investigation of the prevalence of central auditory processing disorder (CAPD) within the prison system is warranted.
