Abstract

Malingered psychopathology has the potential to be a costly social problem and there is a need for studies that compare the malingering detection capabilities of tests of psychopathology. This study investigated the capacity of two measures to detect simulated psychopathology. Forty-one first-year psychology students were randomly allocated to experimental groups that included malingering and control conditions. Analogue malingerers were given a financial incentive to simulate believable psychological impairment. Controls received standardised test instructions and the prize incentive, contingent on good effort. Using a between-groups simulation design, group differences on the Personality Assessment Inventory and the revised Symptom Checklist 90 were assessed. Group comparisons revealed elevation of the majority of clinical index scores among malingerers and a consistent pattern of results across tests. Analysis of the test operating characteristics of the malingering indices for these measures revealed superior detection of simulated malingering using the PAI, particularly Rogers' Discriminant Function, although classification accuracy of all malingering indexes was improved when adjusted cut-offs were used. Overall, results from this study demonstrate the vulnerability of the PAI and SCL-90-R to simulated psychopathology, but also the capacity of these measures to detect such performance when specific indexes are used.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
