Concurrent Validity and Diagnostic Efficiency of the Kaufman Brief Intelligence Test in Assessing Severe Discrepancy in Reevaluations of Students with Learning Disabilities.
Canivez, Gary L.
This study examined the concurrent validity and diagnostic efficiency of the Kaufman Brief Intelligence Test (K-BIT) with 75 elementary and middle school students with learning disabilities, who had been referred for triennial multidisciplinary re-evaluations. High and significant correlations were found between the K-BIT and the Wechsler Intelligence Scale for Children-III (WISC-III). However, K-BIT Vocabulary-Matrices discrepancies were not in agreement with WISC-III Performance IQ-Verbal IQ discrepancies. Substantial agreement was found between the presence or absence of achievement-ability discrepancies identified by the K-BIT Composite and the Woodcock-Johnson Revised Tests of Achievement (WJ-R ACH) and those identified by the WISC-III full scale IQ and the WJ-R ACH. Results suggest that diagnostic precision can be maintained and time may be saved by utilizing a brief ability measure (K-BIT) as a substitute for a comprehensive ability measure (WISC-III) in the re-evaluation process of students with learning disability.
