Detection of Feigned ADHD Using the MOXO-d-CPT

Abstract

Objective: The objective of this study was to assess the MOXO-d-CPT utility in detecting feigned ADHD and establish cutoffs with adequate specificity and sensitivity. Method: The study had two phases. First, using a prospective design, healthy adults who simulated ADHD were compared with healthy controls and ADHD patients who performed the tasks to the best of their ability ( n = 47 per group). Participants performed the MOXO-d-CPT and an established performance validity test (PVT). Second, the MOXO-d-CPT classification accuracy, employed in Phase 1, was retrospectively compared with archival data of 47 ADHD patients and age-matched healthy controls. Results: Simulators performed significantly worse on all MOXO-d-CPT indices than healthy controls and ADHD patients. Three MOXO-d-CPT indices (attention, hyperactivity, impulsivity) and a scale combining these indices showed adequate discriminative capacity. Conclusion: The MOXO-d-CPT showed promise for the detection of feigned ADHD and, pending replication, can be employed for this aim in clinical practice and ADHD research.

Eye Tracking During a Continuous Performance Test: Utility for Assessing ADHD Patients

“…The study received an institutional review board (IRB) committee approval and all participants provided written informed consent. The study sample partially overlapped with that of Berger et al (2019).…”

Feigned ADHD Associated Cognitive Impairment: Utility of Integrating an Eye-tracker and the MOXO-dCPT

“…Utility of conjunctive and disjunctive rules to detect feigned ADHD-associated cognitive impairment. Berger et al (2021) created a scale, termed feigned ADHD scale which integrates the contributions of traditional MOXO-dCPT indices to detect feigning. As part of the current study, we assessed the utility of a scale to differentiate the simulators and genuine ADHD patients.…”

“…Finally, they performed the MOXO-dCPT, the WMT's DR-subtest, and filled a debriefing survey inquiring about their motivation to follow the experimental instructions. ADHD patients also filled a brief questionnaire inquiring whether they feigned impairment when originally diagnosed (for additional information, see Berger et al, 2021).…”

Childhood mental health and adult family relationships: How ADHD shapes experiences with intimate unions and parenthood

“…This perspective undergirds the justification of medical treatments aimed at moderating brain activity in efforts to improve attention and reduce hyperactive or impulsive behavior. Proponents of the biomedical model might point to visible differences in brain scans for youth with and without ADHD to characterize the disorder, and to computerized tests and other diagnostic tools to help validate diagnoses (Berger et al., 2019; Lim et al., 2013; Pavlova & Uher, 2020; Quinn, 2003; Shaw et al., 2007; Thomas & Gaffney, 2017; Tucha et al., 2015; Wang et al., 2019).…”
