The Quick Test as a Screening Device for Intellectually Subnormal Children

Abstract

For a sample of 40 educable retarded children, correlations between WISC IQs and Quick Test IQs were .53 (Verbal Scale), .32 (Performance Scale), and .50 (Full Scale). The QT mean IQ was significantly higher than the mean WISC Verbal and Full Scale IQs; there was no significant difference between the QT mean IQ and the mean WISC Performance IQ, although the correlation between these scales was somewhat lower. The findings suggest that, as with the adult retardate, the Quick Test assesses functional language ability of mentally retarded children moderately well and thus may be used in conjunction with other data for screening purposes.
