Abstract

There is a lack of reliability data within the literature for behavioral tests of auditory processing disorder (APD). Thus, the purpose of this study was to evaluate the test-retest reliability of three tests of temporal processing (Frequency Pattern, Duration Pattern, and Gaps In Noise tests) in normal hearing, young adults. The methods of this study included administering the Frequency Pattern (FP), Duration Pattern (DP) and Gaps In Noise (GIN) tests according to each test's owner's manual to normal hearing adults at one test session and then again seven to nine days later. The data was analyzed using a general linear model analysis of variance (ANOVA) for each test individually in order to compare the mean scores obtained at test session one to the mean scores obtained at test session two. Additionally, Pearson r correlation coefficients were analyzed for each test in order to investigate the reliability of each test. The results of this study indicated that there were no significant differences between the mean scores of any of the tests administered across testing sessions. Additionally, moderate to strong correlation data was found (.446 < r < .71). Thus, this study concludes that the FP, DP, and GIN tests are reliable clinical tools.
