Equivalent forms and split-half reliability of the NU-CHIPS administered in noise

The effects of white noise on the equivalent forms reliability and internal consistency reliability of the Northwestern University-Children's Perception of Speech Test (NU-CHIPS) were examined. Subjects were 36 normally hearing 10-year-old children who were assigned randomly in equal numbers to one of three experimental groups. Each group was administered all four forms of the NU-CHIPS at one of three signal-to-noise ratios (S/N = -4, S/N = 0, S/N = +2). The reliability of the NU-CHIPS when presented in noise is diminished relative to its reported reliability when administered in quiet as revealed by Pearson product-moment correlation coefficients.
