A Dutch test series for the measurement of aphasic disturbances is introduced. Factor analyses demonstrate three factors that can be interpreted clearly as spontaneous speech, production and comprehension of speech. This structure is very stable during a follow-up of one year. The tests and the production, comprehension and severity scores derived from them have high indices of reliability. Norms based on 147 cerebrovascular aphasics and 179 normal controls have been calculated.
