Relationship between scores on the Columbia mental maturity scale and the Peabody picture vocabulary test--revised.

Abstract

Screening instruments are vitally important for determining whether or not a child may need a further and more complete assessment. They can also help school personnel make decisions concerning the selection of curriculum materials and learning tasks that are available for all the children. Screening instruments are used to make such decisions because they are quick to administer and cost effective. The present study was designed to establish concurrent criterion-related validity. The relationship between the Peabody Picture Vocabulary Test-Revised (PPVT-R) and the Columbia Mental Maturity Scale (CMMS) was investigated. Fifty-one children (27 boys and 24 girls) were tested with both instruments. They ranged in age from 3 years to 7 Revised AN ABSTRACT OF THE THESIS OF Charlene A.

Furthermore, a Pearson product-moment coefficient was calculated to determine the relationship between the CMMS and PPVT-R. It was very low (r= .18). A 2 X 2 factorial design was conducted to determine if there were gender differences between the CMMS and the PPVTR scores. The Gender X Tests was significant, E(1,49) = 6.26, R<.05. The significant differences were found between the males and females scores on the PPVT-R. The males scored significantly higher. Also, the males scored significantly higher on the PPVT-R than they scored on the CMMS (R<.05). The similar mean scores suggest that the two tests are capable of producing comparable assessments. Nevertheless, the low correlation coefficient demonstrates that the two tests do not produce comparisons of the same equality.
