Comparison of the NES and CNS/B neuropsychological screening batteries

Computer and hand administered neuropsychological tests are utilized in the evaluation of central nervous system changes associated with environmental or occupational exposure to neurotoxicants. This study compares the computerized Neurobehavioral Evaluation System (NES) developed by Baker et al., 1985, with the hand administered California Neuropsychological Screening Battery (CNS/B) developed by Bowler et al., 1986. Both batteries were designed for screening of the effects of neurotoxicants on the central nervous system and require less than one hr to administer. Both screening batteries consist of tests of: mood, word knowledge, attention, concentration, learning and memory and psychomotor and visuomotor and visuospatial abilities. They were administered in a standardized fashion to 106 subjects. Results indicate strong positive correlations for tests of word knowledge, moderate correlations for attention and concentration, while weaker correlations were obtained for tests of memory, psychomotor and visuomotor and visuospatial ability. The NES may be more useful for large epidemiological studies while the CNS/B appears more useful for individual screening and clinical studies.
