IQ test selection could be life-or-death decision: WAIS v SB score differences in ID/MR sample

Monday, February 15th, 2010

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.  Silverman, W., Miezejeski, C., Ryan, R., Zigman, W., Krinsky-McHale & Urv, T.

Friday, November 6th, 2009

In the past I mentioned (at ICDP sister blog) the importance of APA Divisions 33 (Intellectual and Developmental Disabilities) and 41 (American Psychology-Law Society) for psychologists and other professionals interested in Atkins cases.  I recently joined both (although I’ve yet not received confirmation of my secret decoder ring and handshake for Div 33).
