Detection of malingered attention deficit hyperactivity disorder

Area of Science:

• Psychology
• Neurodevelopmental Disorders
• Clinical Assessment

Background:

• Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder impacting adults.
• Accurate diagnosis is crucial, but malingering (feigning symptoms for external gain) poses a challenge.
• Self-report measures are commonly used but their validity in detecting feigned ADHD is under investigation.

Purpose of the Study:

• To investigate the efficacy of a self-report rating scale in detecting simulated adult Attention Deficit Hyperactivity Disorder (ADHD).
• To compare the performance of individuals feigning ADHD with genuine ADHD patients and a control group.

Main Methods:

• Adult university students (N=78) were divided into control, naïve simulation, and coached simulation groups.
• Adults with a diagnosed ADHD (N=12) also participated.
• All participants completed the Brown Attention Deficit Disorder Scale for Adults, with simulation groups instructed to feign ADHD.

Main Results:

• Both the naïve and coached simulation groups successfully feigned ADHD symptoms on the self-report scale.
• The self-report scale was unable to differentiate between genuine ADHD and simulated ADHD in this study.
• This suggests a significant limitation in using such scales for detecting malingering.

Conclusions:

• Self-report rating scales, like the Brown Attention Deficit Disorder Scale for Adults, are not sufficiently sensitive to detect malingering of adult ADHD.
• Clinical assessments for adult ADHD should incorporate multiple methods beyond self-report to ensure diagnostic accuracy.
• Further research is needed to develop more robust methods for identifying feigned ADHD in clinical and forensic settings.
