Validity of WAIS short forms.
A short-form intelligence test is commonly validated by determining irs correlation with the full scale from which it is taken, but it has been argued that this measure is less meaningful than the extent to which the short form agrees with the full scale in classifying individuals. A table is presented showing the theoretical agreement between the best duad, triad, tetrad, and pentad short forms of the WAIS and the Full Scale. Data on agreement may be more helpful than correlational data to the clinician who must decide whether to use a short form in place of the Full Scale.
