Abstract

Regression equations developed by Crawford, Allan & Jack (1992) to estimate full-length WAIS-R IQs from seven short-forms were evaluated in healthy (N = 153) and neurological (N = 471) cross-validation samples. In the healthy sample the correlations between the short-forms and full-length IQs did not differ significantly from those obtained by Crawford et al. (1992). In the neurological sample the six- and seven-subtest short-forms, proposed by Crawford et al. (1992) and Warrington, James & Maciejewski (1986) respectively, differed from the other short-forms in that they had significantly higher criterion validity coefficients and did not systematically under- or overestimate IQs.
