Factor Analysis of the Clinical Scales on the Luria-Nebraska Neuropsychological Battery, Form II

PDF Version Also Available for Download.

Description

The Luria-Nebraska Neuropsychological Battery (LNNB) was published in 1980 as an attempt to provide clinicians with a standardized version of the neuropsychological assessment and diagnostic procedures proposed by A. R. Luria and A, L. Christensen. Research on the LNNB included a series of factor analyses for each of eleven clinical scales. The analyses were completed on the combined scores obtained from a sample of normal, brain-damaged, and psychiatric populations. A second version of the LNNB was published in 1985 as a largely parallel version of Form I, but included changes in stimulus materials, administration procedures, and scoring procedures. The present ... continued below

Description

The Luria-Nebraska Neuropsychological Battery (LNNB) was published in 1980 as an attempt to provide clinicians with a standardized version of the neuropsychological assessment and diagnostic procedures proposed by A. R. Luria and A, L. Christensen. Research on the LNNB included a series of factor analyses for each of eleven clinical scales. The analyses were completed on the combined scores obtained from a sample of normal, brain-damaged, and psychiatric populations.
A second version of the LNNB was published in 1985 as a largely parallel version of Form I, but included changes in stimulus materials, administration procedures, and scoring procedures. The present study completed factor analyses on same eleven clinical scales using data generated with the newer LNNB Form II. The statistical procedures and criteria employed in the present investigation were identical to those used earlier on Form I to allow for comparisons between the two resulting sets of factor structures. The patient populations were different, however, in that all subjects in the current study were receiving inpatient care in a private psychiatric hospital which specializes in long-term treatment.
Despite the changes in materials and procedures and the difference in subject parameters, the factors identified in the present investigation are similar to those seen in the Form I studies. However, two trends were observed when comparing the two sets of factor structures. First, in the present study several items were excluded from the statistical procedures because they were performed perfectly by almost everyone and the resulting scores lacked statistical variance. Second, more homogenous factors were obtained with the Form II analysis. That is, some of the complex LNNB Form I factors were reduced to two or more simpler factors. The results of the study lend support to Luna's conceptual model of higher cortical function and to the reliability of the LNNB as an assessment instrument.
