Detection of Feigned ADHD Using the MOXO-d-CPT.

Area of Science:

• Neuroscience
• Psychology
• Clinical Research

Background:

• Distinguishing genuine Attention Deficit Hyperactivity Disorder (ADHD) from malingered presentations is crucial for accurate diagnosis and treatment.
• The MOXO Continuous Performance Test (MOXO-d-CPT) is a potential tool for assessing ADHD symptoms.

Purpose of the Study:

• To evaluate the MOXO-d-CPT's effectiveness in detecting feigned ADHD.
• To establish reliable cutoffs for specificity and sensitivity in identifying simulated ADHD.

Main Methods:

• A two-phase study comparing healthy adults feigning ADHD, healthy controls, and diagnosed ADHD patients (n=47 per group).
• Utilized the MOXO-d-CPT and a performance validity test (PVT) in a prospective design.
• Retrospectively analyzed MOXO-d-CPT classification accuracy against archival data.

Main Results:

• Individuals simulating ADHD performed significantly worse on all MOXO-d-CPT indices compared to controls and ADHD patients.
• Three specific MOXO-d-CPT indices (attention, hyperactivity, impulsivity) demonstrated adequate discriminative capacity.
• A composite scale integrating these indices also showed significant discriminative ability.

Conclusions:

• The MOXO-d-CPT demonstrates potential for detecting feigned ADHD.
• Further replication is recommended before widespread clinical and research application for feigned ADHD detection.
