Comparison of the Peabody Picture Vocabulary Test and the Stanford-Binet Intelligence Scale in School Age Children

<p>The correlate relationships and directionality and magnitude of mean differences between MAs and IQs of the Peabody Picture Vocabulary Test and Revised Stanford-Binet Intelligence Scale (both 1960 and 1972 norms) were investigated in a sample of 225 school age children. It was found that MAs of two instruments were more highly correlated than the IQs. For the total sample, no significant differences were found between mean MAs of the two instruments. The correlation between PPVT and the 1960 Revised Stanford-Binet IQs and the correlation between PPVT and 1972 Revised Stanford-Binet IQs were found to be identical. The PPVT was found to consistently overestimate both 1960 and 1972 Revised Stanford-Binet IQs. The 1972 restandardization of the Stanford-Binet appears to have increased the difference in IQs of the two instruments. It is suggested that the PPVT be used for screening purposes only and even then with caution. It is also suggested that the PPVT be restandardized on a sample more representative of the U.S. population in order to improve its efficiency in predicting Stanford-Binet IQs.</p>
