Measures of Concurrent Validity and Alternate-Form Reliability of the Test of Nonverbal Intelligence

Abstract

The subjects, 60 undergraduate students, were administered the Test of Nonverbal Intelligence (TONI) individually. The Shipley Institute of Living Scale was administered in small groups. A Pearson correlation of .56 was obtained for TONI Quotients, Forms A and B. TONI Quotients, Forms A and B, correlated with Shipley estimated WAIS—R IQ .50 and .46, respectively, and corrected to .71 and .64, with Shipley Total T scores, .52 and .44, respectively (corrected to .71 and .61), with Shipley Abstraction T scores, .51 and .42, respectively (corrected, .63 and .52), and with Shipley Vocabulary T scores .26 and .32, respectively (corrected to .63 and .52). TONI scores seem more closely related to Shipley Total and Abstraction scores than to Shipley Vocabulary.
