Assessing patient’s subjective experience of illness is an important component of neuropsychological assessment. This information can be assessed using standardized self-reported complaint (SRC) checklists and may have specific applications in the assessment of malingering. Previous research suggests that subjective complaints can be faked under some circumstances, however, the extent to which this occurs when assessments are made using standardized SRC measures is less well understood. In addition, if complaints can be faked, this raises the question: What might reduce the likelihood of faked symptom reports? In this study, we randomly allocated 60 first-year undergraduate subjects to one of the three conditions: malingering, malinger-with-warning, and control. Using a repeated-measures analogue design, we assessed differences between groups on selected SRC measures. The measures used were the Neuropsychological Symptoms Checklist (NSC), the General Health Questionnaire-30 (GHQ-30), and the Depression, Anxiety, and Stress Scales (DASS). We expected to find that SRC measures would be vulnerable to faking, but also that warning malingerers about the possibility of detection would reduce faking behavior. Further, control group scores on SRC measures were calculated to produce preliminary complaint base rate data for these tests. Our results showed that SRC measures were vulnerable to faking. In addition, contrary to expectations, we found that warnings did not significantly deter malingering, although we observed that a trend in the expected direction and future studies with a larger sample size or a modified warning may be needed to further investigate warning efficacy. Broader implications of these findings are discussed in light of deterrence theory and recent debate over the use of SRC measures in the assessment of malingering. © 2002 National Academy of Neuropsychology.
