Concurrent validity study of the Slosson Intelligence Test-Revised in mental retardation testing.
The new Slosson Intelligence Test-Revised and the recommended abbreviated battery of the Stanford-Binet Intelligence Scale: Fourth Edition were given to individuals whose Stanford-Binet IQs ranged from 36 to 110. The Slosson-R correlated highly with the Stanford-Binet, r = .92. However, except for the moderately retarded category, the Slosson-R unsatisfactorily matched the Stanford-Binet's assignment of individuals to IQ categories. In contrast, when all individuals were classified as either having or not having mental retardation, the match rate was much better. The Slosson-R can adequately screen for mental retardation, but its ability to accurately assign individuals to specific IQ categories appears to be limited.
