Wn. Robiner et al., USE OF THE REYNOLDS, WILLSON, AND CLARK WAIS-R SHORT-FORM IN A BRAIN-INJURED POPULATION - A CAUTIONARY NOTE, Clinical neuropsychologist, 11(1), 1997, pp. 91-95
A short form (Information, Arithmetic, Picture Completion, and Block D
esign) of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) devel
oped by Reynolds, Willson, and Clark (1983) was used to estimate Full
Scale IQ in brain-injured persons. Estimated IQ correlated .91 with WA
IS-R Full Scale IQ, but overestimated IQ by a mean of 5.94 points. The
pattern of overestimating IQ with brain-injured persons (p < .001) su
ggests that the Reynolds et al. short-form (RWCSF) procedure is not ap
propriate for brain-injured patients and raises questions about its us
e with other individuals who have cognitive or neurological impairment
