The purpose of this study was to derive an embedded validity index of effort for the Stanford-Binet Intelligence Scales-Fifth Edition (SB5; Roid, 2003a) and to validate this index using an analog sample of individuals feigning mild mental retardation (MR). Of the data provided by Dr. Roid, 307 healthy individuals aged 18-35 with full scale intelligence quotients (FSIQ) greater than 70 were included in this study (n = 307) as well as 31 individuals with FSIQ scores in the MR range. Also, a sample of 108 undergraduate students at Louisiana State University was asked to participate in this study in exchange …
