Meten van taalbegrip en taalproductie:constructie, normering en validering van de Reynell Test voor taalbegrip en de Schlichting Test voor taalproductie

摘要

This thesis renders an account of the research, conducted for of the construction, standardisation and validation of two tests for the measurement of language development in children between the ages of fifteen and seventy­eight months. The tests that were developed are the Reynell Test voor Taalbegrip (RTB) and the Schlichting Test voor Taalproductie (STP). The tests are designed to diagnose children's language problems. The starting point for the design was formed by the Reynell Developmental Language Scales (RDLS; Reynell, 1977, 1985). The RTB can be seen as an elaborate revision (and Dutch translation) of the RDLS. The STP was newly designed during the research project. The central question in this thesis concerns the instrumental utility of the tests: do the tests answer their purpose? To answer this question a description is given of the construction of the tests, the guidelines for this construction and the standardisation research. Also an account is given of the research conducted in order to establish the reliability and the validity of both tests.
