| Popis: | The major objective of the current investigation was to provide an evaluation of the validity of the ITPA for language-impaired children using confirmatory factor analysis. In addition to an examination of the validity of the traditional ITPA models, a new model is tested. The new model is based on considerations of the structural complexity of the ITPA subtests. and allows one to interpret ITPA results in processing terms. The results suggest that four-factor models provided the best representation of the ITPA scores in language-impaired children. Compared with the traditional ITPA models, the new model showed either an improved or equal goodness of fit. Language-impaired children tested with the ITPA (n = 100) exhibited a profile pattern suggesting that subtests with low processing demands are "easier" than tests with high processing demands. Thus, the present study supports the contention that language-impaired children suffer from constraints on information processing. |
