Relationships between scores on the Kaufman brief intelligence test and the Wechsler adult intelligence scale: third edition.

Abstract

This study investigated the concurrent validity of the Kaufman Brief Intelligence Test (K-BIT) as a test of adult intelligence. Participants were 20 undergraduate Psychology students of Emporia State University. Results indicated the Kaufman Brief Intelligence Test estimates IQ levels at an average of three points less than the Wechsler Adult Intelligence Scale, Third Edition (WAIS-III). All correlations between comparable scales were high according to Guilford correlation criteria (Sprinthall, 2000). The K-BIT appears to be valid as a test of adult intelligence within this population.
