Correlations between the Quick Test Forms 1 and 3 and Peabody Picture Vocabulary Test for Children and Youth with Learning Problems

Abstract

The Quick Test, Forms 1 and 3 and the Peabody Picture Vocabulary Test were administered to 94 children and youth (58 boys and 36 girls) who were referred to a clinic for suspected learning problems. Chronological ages for the sample ranged from 7–4 to 14–5, with a mean of 12–8. Analysis showed no significant differences between the means of the boys and girls on the scores of Quick Test 1 and 3. A pervasive pattern of strong positive correlations was found between the Peabody Picture Vocabulary Test and Quick Test, Forms 1 and 3; and between the two forms of the Quick Test. The findings indicate that the Quick Test provides a reasonable estimate of conventional verbal intelligence as well as being very stable even with populations whose intelligence test performance is often highly variable.
