Abstract:

Describes a factor analysis with principal components extraction and varimax rotation performed on 19 California Verbal Learning Test age-uncorrected scores from a sample of 75 patients with traumatic brain injury (TBI) caused by moderate and severe closed head injuries. A 6-factor solution was obtained that accounted for 80% of the total variance and was similar to those reported previously. The factors were labeled General Verbal Learning, Response Discrimination, Learning Strategy, Proactive Effect, Self-monitoring, and Serial Position.
