A t-test was used to examine group differences on
age, education, and premorbid IQ (WRAT-4) variables. Fisher’s exact test was
used to examine group differences on gender, race, premorbid mental health, and
duration of loss of consciousness variables. Chi-square test was used to
examine group differences on mechanism of injury. Mann-Whitney U test was used
to examine group differences on days since injury variable.
