Abstract
The influence of factors such as cerebral injury characteristics, education, perceptual organization skills, and speed of information processing on performance on the Rey Complex Figure Test & Recognition Trial (RCF) was examined by means of hierarchical regression analyses in 100 consecutively referred persons with traumatic brain injury at a median of 2.5 months post-injury. Patients with premorbid (e.g., psychiatric history) or comorbid (e.g., financial compensation-seeking) complicating factors were excluded. Perceptual organization skills and the presence of a diffuse intracranial lesion but not education or speed of processing were statistically significant predictors of the variance in RCF variables. A large proportion of the sample improved by at least a standard deviation from independent delayed recall to multiple-choice recognition, and this was mediated by perceptual organization skills but not by injury parameters. It is concluded that performance on the RCF after traumatic brain injury is affected relatively more by perceptual organization skills than by injury severity characteristics.
