Potts HE, Lewandowski LJ, Lovett BJ. Identifying Feigned ADHD in College Students: Comparing the Multidimensional ADHD Rating Scale to Established Validity Measures. Journal of attention disorders. 2022 Oct;26(26). 1622-1630. PMID: 35466735 [PubMed]
There is increased concern for malingering in ADHD evaluations due to presence of incentives such as accommodations and medications. Although several validity tests are available to classify malingering in non-ADHD populations, there is no test with proven effectiveness to detect feigned ADHD. This study investigated the ability of the MARS Symptom Validity Index 4 (MARS SV-index 4) and two published validity tests (the Word Memory Test [WMT] and Clinical Assessment of Attention Deficit-Adult [CAT-A] Infrequency scale) to detect malingered ADHD.
