The primary purpose of this study was to determine list equivalency of Harris' revision of the CID Everyday Sentence Lists under three signal-to-noise ratios: 0 dB, −3 dB, and −6 dB. On the basis of list means, nonsignificant groupings of lists were found at each noise level; however, lists were not equivalent at any level on the basis of a ± 10% standard error of measurement (%YO confidence interval). It is concluded that Harris' revision of the CID Everyday Sentences should not be used in their present form for intraindividual comparisons.
