Factor analysis of computerized and traditional tests used in mild brain injury research.
The present study examines the relation between a set of computerized neuropsychological measures, Automated Neuropsychological Assessment Metrics (ANAM), and a set of traditional clinical neuropsychological tests. Both sets of tests have been employed in recent studies of mild brain injury. Factor analysis and stepwise regression indicate that both sets of tests measure similar underlying constructs of cognitive processing speed, resistance to interference, and working memory. The present findings indicate strong concordance between computerized and traditional neuropsychological measures and support the construct validity of ANAM and similar procedures.
