RESUMEN
Recently there has been growing concern that college students may feign symptoms of ADHD in order to obtain academic accommodations and stimulant medication. Unfortunately research has only begun to validate detection tools for malingered ADHD. The present study cross-validated the results of Sollman, Ranseen, and Berry (2010) on the efficacy of several symptom validity tests for detection of simulated ADHD among college students. Undergraduates with a history of diagnosed ADHD were randomly assigned either to respond honestly or exaggerate symptoms, and were compared to undergraduates with no history of ADHD or other psychiatric disorders who were also randomly assigned to respond honestly or feign symptoms of ADHD. Similar to Sollman et al. (2010) and other recent research on feigned ADHD, several symptom validity tests, including the Test of Memory Malingering (TOMM), Letter Memory Test (LMT), Digit Memory Test (DMT), Nonverbal Medical Symptom Validity Test (NV-MSVT), and the b Test were reasonably successful at discriminating feigned and genuine ADHD. When considered as a group, the criterion of failure of 2 or more of these SVTs had a sensitivity of. 475 and a specificity of 1.00.

Twenty-four studies utilizing the Wechsler Adult Intelligence Scale (WAIS) Digit Span subtest--either the Reliable Digit Span (RDS) or Age-Corrected Scaled Score (DS-ACSS) variant--for malingering detection were meta-analytically reviewed to evaluate their effectiveness in detecting malingered neurocognitive dysfunction. RDS and DS-ACSS effectively discriminated between honest responders and dissimulators, with average weighted effect sizes of 1.34 and 1.08, respectively. No significant differences were found between RDS and DS-ACSS. Similarly, no differences were found between the Digit Span subtest from the WAIS or Wechsler Memory Scale (WMS). Strong specificity and moderate sensitivity were observed, and optimal cutting scores are recommended.
