Relationships Between Language Skills As Assessed by the Halstead-Reitan Battery and the Luria-Nebraska Language-Related Factor Scales in a Nonaphasic Patient Population.

The study involved a comparison between language tests derived from the Halstead-Reitan and Luria-Nebraska neuropsychological test batteries. Language-related measures from each battery were entered into a factor analysis based on a sample of 150 nonaphasic neuropsychiatric patients. Five factors were extracted and were named Academic Achievement, Basic Skills, Verbal Intelligence, Auditory Discrimination, and Comprehension of Syntactical Relations. Measures from both the Halstead-Reitan and Luria-Nebraska loaded on most of these factors. A canonical correlation analysis revealed a strong relationship between the Halstead-Reitan and Luria-Nebraska measures. However, it was noted that interpretation of this relationship must be qualified by the association found between the measures used and educational achievement.
