Abstract

The Luria-Nebraska Neuropsychological Battery (LNNB) is a comprehensive assessment system based on Luria's theory of functional systems of the brain. It remains as the most popular neuropsychological battery across different cultures in past 20 years. This study was to develop a standardized Chinese version of the LNNB on the basis of Luria's theory and the critics' viewpoints. The study have four objectives: (1) to translate and adapt the original test battery into the Chinese language, (2) to conduct item analysis and convert raw scores to scale scores, (3) to establish local norm and total critical level prediction formula, and to derive individual critical level prediction formula for each clinical scale, (4) to compare the differential validity of two kinds of formulas.The new version was evaluated for its representativeness, appropriateness, as well as clarity of test items. The final Chinese version still had 11 clinical scales which consisted of 270 items, called ' LNNB-C'. LNNB-C was then administered to 75 normal controls and 47 brain-damaged patients. Based on test results, new cutoff points of impaired scores for scoring LNNB-C items were established. Overall, new cutoff points for 110 items were established. The number of revised items was similar to the Greek version of the LNNB. Normative data were developed for all 11 clinical scales based on the scores of LNNB-C with 130 normal controls. The critical level prediction formula was derived by a linear multiple regression analysis, with age and education as the independent variables and the mean of T-scores of all clinical scales as the dependent variable. This total-formula of LNNB-C was found to be similar to American and Greek's. In addition, age, education, and sex were found to have differential effects on performance of different clinical scales. Individual-formulas were thus derived separately for different critical scales of LNNB-C. At last, using individual-formula to differentiate patients from controls didn't raise the sensitivity, but it did raise the specificity a little.
