Note: FSIQ= Full Scale Intelligence Quotient, WAIS-III = Wechsler Adult Intelligence Scale, 3^rd Edition, WRAT-3 = Wide Range Achievement Test, 3^rd Edition, RBANS = Repeatable Battery for the Assessment of Neuropsychological Status, SZ-PASS = Individuals with schizophrenia that passed the RBANS Effort Index, SZ-FAIL = Individuals with schizophrenia that failed the RBANS Effort Index. A total of 330 patients had WAIS-III data: 299 SZ-PASS and 31 SZ-FAIL, a total of 329 patients had WRAT-3 data: 298 SZ-PASS and 31 SZ-FAIL, and a total of 330 patients had RBANS data: 299 SZ-PASS and 31 SZ-FAIL.
