Objective: A common SVT is the Test of Memory Malingering (TOMM). Clinicians have recently begun using an abbreviated version of the TOMM; however, to date, no research has specifically looked at children with ADHD. Our hypothesis is that children with ADHD who pass TOMM1 also pass Trial2. Method: Data were collected on 144 children (boys = 66%, girls = 34%; age range 6–18) who were referred due to academic and behavioral problems. All children were diagnosed with ADHD. No children were involved in litigation, custody disputes, or recent accidents or had intellectual disability or brain injuries. Participants completed a neuropsychological evaluation and data was analyzed via SPSS. Analyses included frequencies, SN, SP, PPV, and NPV. Results: Mean FSIQ was 88.7 (15.9). On TOMM1, 40% (n = 58) of the sample scored below the established cutoff. Of those who scored above the TOMM Trial2 cutoff on Trial1, 100% (n = 86) went on to meet/exceed the cut score for Trial2. TOMM Trial1 scores were significantly positively correlated with TOMM Trial2 scores (r = .631, p = .000). For TOMM1, optimal results were >40 (SN = 90%, SP = 92%, NPV = 99%). Conclusion(s): Growing data support a high likelihood of passing Trail2, if Trial1 was passed. Our results indicate that a score < 40 on Trial1 is suggestive of poor effort and a high likely to fail the TOMM in children with ADHD. If a passing score is achieved during Trial1, 99% of cases also passed Trial2. Only administering Trial1 to determine effort could be time and diagnostically efficient.
