Abstract
The relationship between depression and performance on selected neurocognitive tests was examined in two mild head injury samples (n 1 =72, n 2 =50). A series of hierarchical regression analyses showed that scores on depression-related scales of both the MCMI-II (Millon Clinical Multi-Axial Inventory; Millon, 1987) and MMPI-2 (Minnesota Multiphasic Personality Inventory; Hathaway & McKinley, 1989) were largely independent of cognitive performance. Depression may be prevalent in mild injury, but it is unlikely to mediate deficits observed on commonly used measures of problem solving, visual-motor speed, prose and figural recall.
