Concurrent validity of the universal nonverbal intelligence test and the Leiter International Performance Scale-Revised

摘要

One hundred elementary- and middle-school students were administered the Universal Nonverbal Intelligence Test (UNIT; B.A. Bracken & R.S. McCallum, 1998) and the Leiter International Performance Scale-Revised (Leiter-R; G.H. Roid & L.J. Miller, 1997). Correlations between UNIT and Leiter-R scores were statistically significant (p < .001), ranging from .33 to .74. The UNIT Full Scale score was 5 points higher than the Leiter-R Full Scale score, t = 4.73, p < .001. (c) 2006 Wiley Periodicals, Inc.
