dc.description.abstract This thesis explored the concurrent validity of the Quick Test (QT) as a brief individual measure of intelligence by correlating it with the Wechsler Preschool and Primary Scale of Intelligence (WPPSI). The subjects were 72 urban preschool children (15 black, 57 white) from Muncie, Indiana. The subjects ranged in age from 4½ to 6½ years, and were chosen from diverse socioeconomic backgrounds. Subjects were randomly assigned to two groups, each comprised of 36 females and 36 males. Tests were administered by two graduate students in clinical psychology and rotated to control for the effects of testing order. The correlation coefficients between the QT and WPPSI Full, Verbal and Performance Scale IQs were r = .64, r = .67 and r = .52, respectively. All correlations were significant at the .001 level. The strong correlation (r = .67) between the WPPSI Verbal and QT IQ suggests that the QT may be a good brief measure of verbal intelligence. The mean IQs for the WPPSI Full (102), Verbal (99), and Performance (106) were all significantly different (p < .001) from the QT mean IQ of 92. This seems to suggest that the WPPSI and QT mean IQs should not be used interchangeably. Standard deviations for the WPPSI Verbal, Performance, Full Scale, and QT IQs were 14.63, 16.85, 15.92, and 20.51, respectively. The present concurrent validity is strong enough to support the use of the QT as a brief individual measure of verbal intelligence.
