Development and public release of the Penn Reading Assessment Computerized Adaptive Test (PRA-CAT) for premorbid IQ.

ABSTRACT: An important component of neuropsychological testing is assessment of premorbid intelligence to estimate a patient's ability independent of neurological impairment. A common test of premorbid IQ-namely, the Reading section of the Wide Range Achievement Test (WRAT)-has been shown to have high measurement error in the high ability range, is unnecessarily long (55 items), and is proprietary. We describe the development of an alternative, nonproprietary, computerized adaptive test for premorbid IQ, the Penn Reading Assessment (PRA-CAT). PRA-CAT items were calibrated using a 1-parameter item response theory model in a large community sample (N = 9,498), Ages 8 to 21, and the resulting parameters were used to simulate computerized adaptive testing sessions. Simulations demonstrated that t
