Subscale classification schemata for the Stanford-Binet, form L-M

366 Stanford-Binet (S-B) protocols were scored according to subscale categories proposed by Valett (1963–64), Sattler (1965), and Meeker (1969). The mean age of the Ss was 9.24 years and the mean IQ was 99.43. Intercorrelations were computed for the subscales, sex, socioeconomic status, mental age, and vocabulary score and factor analyses performed on each of the subscale intercorrelation matrices. The intercorrelations were significant for all variables except sex. Only one general factor was found for each of the schemata. It was concluded that in the absence of factorial validity, the use of such subscales is invalid.
