An orthogonal factor solution for the receptive speech scale of the Luria-Nebraska Neuropsychological Battery

Previous principal components factor analyses with oblique rotation to simple structure have produced widely disparate results for the Receptive Speech Scale of the Luria-Nebraska Neuropsychological Battery (LNNB). Four of six scales based on the second factor solution lack internal consistency. A new principal components factor solution was computed with Varimax orthogonal rotation to simple structure for the current study. Three factors emerged that matched the strongest factors of the previous factor solutions closely. Internal consistency of the obtained factors was satisfactory. Theoretical implications and issues for clinical application were discussed.
