Microsoft Kinect-based Continuous Performance Test: An Objective Attention Deficit Hyperactivity Disorder Assessment

Area of Science:

• Child and Adolescent Psychiatry
• Biomedical Engineering
• Neuroscience

Background:

• Accurate and objective evaluation of Attention Deficit Hyperactivity Disorder (ADHD) is a major challenge in mental healthcare.
• Early identification and prompt treatment of ADHD are crucial to mitigate negative outcomes.
• Current assessment methods often lack objectivity, necessitating novel approaches.

Purpose of the Study:

• To develop a novel ADHD assessment instrument utilizing Microsoft Kinect technology.
• To identify cardinal symptoms of ADHD for improved diagnostic accuracy.
• To explore objective measures for ADHD evaluation in children.

Main Methods:

• A cohort of 30 children (aged 8-12) meeting DSM-5 ADHD criteria participated.
• Parental Strengths and Weaknesses of ADHD Symptoms and Normal Behavior (SWAN) scale ratings were collected.
• A Kinect-based Continuous Performance Test (CPT) measured reaction time (RT) and completion time (CT), with commission errors noted.

Main Results:

• Reaction time (RT) showed correlations of -.11, -.29, and -.37 with inattention, hyperactivity, and impulsivity, respectively.
• Commission errors correlated with inattention (-.03), hyperactivity (.01), and impulsivity (.24).
• A significant relationship was observed between Kinect-based CPT performance and ADHD symptomatology via parental reports.

Conclusions:

• The study demonstrates a link between a Microsoft Kinect-based CPT and ADHD symptomatology.
• Findings underscore the need for continued research into objective diagnostic tools for ADHD.
• Objective measures can enhance the accuracy and efficiency of ADHD diagnosis in pediatric populations.
