Clinical Utility of the Tower of London—Drexel University, Second Edition (TOL^DX) After Adolescent Traumatic Brain Injury

Abstract

The performance of 43 adolescents with traumatic brain injury was evaluated on the Tower of London—Drexel University, second edition (TOL^DX; Culbertson & Zillmer, 2005), and compared to that of 43 demographically matched healthy controls. TOL^DX variables had a classification accuracy of 69.77%, with clinical patients demonstrating deficits in pre-planning of a schema as well as keeping subgoals in spatial working memory during execution. Time to follow commands and diffuse lesions on neuroimaging accounted for moderate amounts of variance in TOL^DX variables. The findings support the clinical utility of the TOL^DX in the assessment of adolescents with traumatic brain injury.
