Interesting article “in press” in Intelligence that compares WAIS and Stanford Binet IQ scores (across different editions except the current SB5 and WAIS-IV) for adults with intellectual disability (ID/MR). Although the mixing together of scores across different editions makes it impossible to make SB/WAIS-specific edition comparisons, the finding that the WAIS scores were, on the average (mean), almost 17 points higher may surprise many psychologists. The authors discuss the real-life implications (i.e., Atkins ID death penalty decisions; eligibility for SS benefits, etc.) of different scores from different tests. As outlined in a prior IAP AP101 special report , differences of this magnitude between different IQ tests should not be surprising.

I ran a search of the ProQuest Digital Dissertation Database in search of studies involving the most recent versions of the WAIS-IV and WISC-IV .

I should have included the following tables in my original AP101 Brief # 6 report re: my analysis of the CHC content of the FS IQ scores for the various editions of the WISC–WIS-IV/WAIS–WAIS-IV intelligence batteries.

Below is a response to my prior post regarding Wechsler-like scaled score issues. The response was on the NASP listserv and the authors gave me permission to reproduce it “as is” below. I’m pleased that they concur with the recommendations at the end of the paper post. Kevin McGrew’s argument can be turned around to show that using subtest score metrics with larger SDs also may lead to misinterpretation if a change of 1 raw score point leads to a change of many standard score points. So, the issue is not as simple as which subtest metric is better (e.g, the Wechsler / Kaufman metric or the WJ metric).
Read the rest here:
