title: Validity of the Luria-Nebraska language scales in aphasia.
abstract: The language scales of the Luria-Nebraska Neuropsychological Battery (LNNB) were administered to patients classified as either Broca's (n = 7) or Wernicke's (n = 7) aphasics. Group comparisons were made on the standard scales (e.g., Receptive Speech, Expressive Speech, Reading & Writing) and on 13 factor-analytically derived subscales (McKay & Golden, 1981). Results indicated that the standard T-score profile failed to discriminate the distinctively different language syndromes. Only two of the 13 factor scales differentiated the groups. Although Wernicke's patients were more impaired than Broca's patients on factor-analytically derived measures of basic language comprehension, it was concluded that the subscales added little to the standard profile in terms of aphasia syndrome identification. Distinctively different profiles of impaired and retained language abilities did not emerge on the LNNB factor scales. The battery cannot be recommended for use with aphasic patients.
