Zusammenfassung:The utility of the Rasch logistic measurement model in longitudinal analyses of children's self-concept was investigated. Calibration of an 80-item self-concept measure from the responses of 1,000 elementary school children resulted in the identification of 25 items that fit the model. Repeated measures analyses of variance used to assess the effects of an experimental intervention program on changes in individuals' self-concept tended to support the usefulness of the measure in reducing the number of test items needed to measure the latent variable in question. Some evidence on the claim for item subtest equivalence also was obtained. (Author/RC)
