Internal consistency and discriminant validity of the Luria Nebraska Neuropsychological Battery-III

This research presents data pertaining to the development of the recently revised Luria Nebraska Neuropsychological Battery-III. The final version of this test battery consists of 31 clinical scales yielding 35 scores. The battery was given to 109 non brain-injured controls and 119 brain-injured subjects. High internal consistency was demonstrated for each clinical scale. Results further indicated that the test battery was very effective at discriminating between normal and brain-injured subjects, as significant between-group differences on 33 of 35 scores were observed. Significant between-group differences were also observed on 25 of the 35 scores when age and education were covaried out of the analyses; those scales not displaying significant between-group differences generally measured very basic over-learned skills.
