The psychometric characteristics of a phonological processing battery were examined using kindergarten (n = 95), first grade (n = 49), and second grade (n = 89) subjects enrolled in public schools. The phonological battery consisted of subtests measuring phonological awareness, phonological access, and phonological coding. The battery also included reading achievement, general intellectual ability, and letter naming/sound knowledge subtests as criterion measures. / The reliability of the battery was assessed by examining both internal consistency estimates and test-retest reliability across all three grades. The internal consistency coefficients for the battery across all ages were satisfactory, with coefficients in the general range of.72 to.95. Test-retest reliabilities over an average interval of 12 weeks were considerably lower (range of.59 to.79 across subtests and grades). / Evidence for the construct validity of the battery included significant correlations among measures of phonological awareness, phonological coding, and phonological access across all three grade levels. For the kindergarten and second grade samples, phonological awareness subtests were significantly correlated, even when the effects of IQ were removed from the matrices. Although the correlations between subtests measuring the three types of phonological processing abilities were minimally significant, factor analytic data supported the existence of separate factors, each of which included subtests representing the three types of phonological processing abilities. / Finally, concurrent validity evidence supported a moderate relationship between the phonological processing measures and reading achievement. Multiple regression analyses identified several subtests which accounted for significant proportions of the variance in reading achievement. Based on the reliability and validity data obtained using this data, a condensed battery was recommended for future research on phonological processing and reading. / Source: Dissertation Abstracts International, Volume: 51-02, Section: B, page: 1015. / Major Professor: Joseph K.
