Abstract:

Objective: To examine whether the Wide Range Achievement Test-3 (WRAT-3) Reading subtest (S. Jastak & G. S. Wilkenson, 1984; G. S. Wilkinson, 1993) measures premorbid intelligence in persons with traumatic brain injury (TBI). Participants: Sixty individuals (63% male, 78% Caucasian, mean age = 38 years) tested during acute rehabilitation hospitalization following TBI and 1 year later. Results: Slight (4.4 points) increase in WRAT-3 Reading scores was observed but with greater, although nonsignificant (p = .12), increase for those with greater injury severity. Conclusions: The WRAT-3 Reading subtest is a better hold test for individuals who sustain mild TBI.
