The present study was conducted in order to evaluate abbreviated forms of the Wechsler Preschool and Primary Scale of Intelligence for a kindergarten population. Full scale WPPSIs were administered to 24 kindergarten students and the protocol were rescored into each of the following short forms: split-half; Information, Vocabulary, Arithmetic, Comprehension, Picture Completion and Block Design; Information, Arithmetic, Picture Completion and Block Design; Information, Vocabulary and Block Design; and Vocabulary and Block Design. The scores obtained on the abbreviated forms were then compared with the full scale WPPSI as well as with WISCs and Binets for the same population. It was found that all abbreviated WPPSls correlated more highly with the WPPSI full scale than with either the WISC or the Binet. Part-whole correlations of each of the short forms with the full form showed that the split-half was the most closely related to the full scale (r=.920), followed in order by the 6-, 4-, 3-, and 2- subtest combinations. Brevity of the short forms was directly related to their variance and deviation from the full scale. On the basis of the standard error of estimate for the abbreviated forms, as well as their relatively frequent misrepresentation of intelligence classification, it was concluded that they are best suited for nothing more specific than gross intellectual screening. Generalizations from the present study were limited because of the small size and relatively narrow intellectual and socioeconomic range of the population.
