Factor analysis and matrix invariance of the HRNB-C category test.
This study examined the factorial invariance of the six individual Halstead-Reitan Neuropsychological Battery for Older Children (HRNB-C) Category subtests. The test scores for two large samples of learning disabled children were factor analyzed. A three-factor solution emerged for each group with a clear pattern of variable loadings. Category subtests IV and V load on Factor 1, subtests III and VI on Factor 2, and subtests I and II on Factor 3. Variable loadings were not only of similar pattern, but also magnitude and sign for both samples. Moreover, comparison statistics indicate an excellent fit between the two factor matrices. Results support the conclusion that the HRNB-C Category Test measures more than a single underlying construct.
