Comparisons were made between initial test scores of the Luria-Nebraska Neuropsychological Battery, the Factor scales and the Localization scales, and a second set of scores derived from a readministration of the battery. Thirty random, unscreened, psychiatric inpatients with a wide variety of diagnoses served as subjects. Patient condition was not controlled, and no subjects were dropped from the data pool. Sixteen males and 14 females with a mean age of 31.8 years (SD = 12.7), mean education of 9.3 years (SD = 3.2), and a test-retest interval mean of 8.1 months (SD = 6.0) participated. All patients had significant emotional difficulties which resulted in repeated hospitalization, and all were cooperative with test procedures. Test-retest scores for the 14 Luria scales ranged from .83 to .96, averaging .89 and for the eight Localization scales, and the reliability ranged from a low of .78 to a high of .95, with a mean of .89. The factor scales test-retest reliability coefficients ranged from .01 to .96, with a .75 average for the 30 scales. All the correlations, except two on the Factor Scales, were significant at p less than .001. These results support the findings of an earlier study which focused on the 14 Luria scaled scores only. The data suggest that the Luria Battery is reliable over time.
