Abstract

Background: In recent years, there has been a growing concern of potential ADHD malingering in society. This has created a greater demand for developing and testing measures to detect feigning. The study aims to build upon the established framework for identifying feigned ADHD in the following ways: by investigating whether a previously unvalidated for ADHD symptom validity measure, the Self-Report Symptom Inventory (SRSI), is effective at detecting feigned ADHD; by further validating existing measures. Method: One hundred twenty-two participants took part in the study, comprising three separate groups: ADHD patients (N = 25); feigning (N = 43); control (N = 55). The current study uses a simulation design to test several measures in their efficacy at identifying feigned ADHD, including the: Self-Report Symptom Inventory Pseudo Symptom scale (SRSI-PT); Conners’ Adult Attention Deficit/Hyperactivity Rating scales (CAARS); the Reliable Digit Span (RDS). Results: The following specificities and sensitivities were observed, respectively: 64%, 72.09% for the SRSI-PT; 100%, 65.12% for the CAARS CII; 100%, 34.88% for the CAARS ACI; 100%, 67.44% for the RDS. Conclusion: The SRSI-PT has proven to be a promising measure for detecting feigned ADHD as it was found to have a high sensitivity and a similar effect size as the promising CAARS F-scale from a similar study. It was also found to have a low specificity (64%). Discussion: The SRSI-PT has been observed to have a high sensitivity and low specificity. With future analysis and revision of pseudo items commonly reported by ADHD patients, the specificity could improve. Keywords: ADHD, feigning, malingering, SVT, PVT.
