摘要
The Disability Determinations Service (DDS) obtains evidence about an applicant from sources that may include the Psychological Consultative Examination (PCE), which usually includes a mental status examination and Wechsler Scale findings. Although evidence for good effort is necessary to validate the findings, psychologists have been officially discouraged from determining effort by the use of formal tests. In Chafetz, Abrahams, and Kohlmaier (2007), indicators of effort within the PCE in WAIS-age (adults) and WISC-age (children) claimants were determined, and a PCE Malingering Rating Scale was developed. In the present study, this new scale was used along with established symptom validity tests (SVTs) to determine base rates and additional predictors of malingering within the PCE. Claimants were apportioned into separate effort groups in a "dose-response" manner: Definite Malingerers, Chance-Level, Fail Both (SVT and Rating Scale), Fail One, Fail Indicators, and Not Fail. Data from separate studies using the Test of Memory Malingering (TOMM), and the Medical Symptom Validity Test (MSVT) were used to assign claimants into separate effort groups. An evidence-based assessment approach utilized these base-rates to calculate post-test odds. Other predictors of effort within the PCE include the presence of conduct disorder symptoms, and the number of other family members on Disability.
