Correlations Among the Quick Picture Reading Test and the Shipley Institute of Living Scale with the Slasson Intelligence Test-Revised

The purpose of this study was to appraise the potential interrelatedness of three instruments of potential use to school and educational psychologists. This study examined intercorrelations among scores on the Quick Picture Reading Test-Research Edition (QPRT), the Shipley Institute of Living Scale (SILS)- Research Edition, and the Slosson Intelligence Test Revised-3 (SIT-R-3). A sample of 120 children and adults with ages from 7 to 82 completed each test. The results demonstrate correlations between the SIT-R-3, the QPRT, and the SILS vocabulary standard scores were relatively high, while the other correlation coefficients obtained were slightly lower. These results suggest that while the tests may measure some common aspects of reading ability and intelligence, they are also each measuring some particular dimensions of intelligence, providing unique information about the participant.
