Reliability and validity of the Online Continuous Performance Test among children

Area of Science:

• Child Psychology
• Neurodevelopmental Disorders
• Cognitive Assessment

Background:

• Attention deficits significantly impact children's academic and social functioning.
• Accurate assessment of sustained attention and response inhibition is crucial for diagnosis and intervention.
• Existing Continuous Performance Tests (CPTs) may have limitations in real-world applicability.

Purpose of the Study:

• To evaluate the reliability and validity of a novel Online Continuous Performance Test (OCPT).
• To assess the OCPT's ability to measure sustained attention, response inhibition, and response time consistency in children.
• To determine if the OCPT can differentiate between children with and without Attention Deficit Hyperactivity Disorder (ADHD).

Main Methods:

• Seventy-three children (ages 6-13) participated, including 47 with ADHD and 24 controls.
• Parental interviews using the Diagnostic Interview Schedule for Children confirmed group diagnoses.
• Children completed the OCPT in a lab, with a follow-up at home one week later.

Main Results:

• The OCPT demonstrated high split-half reliability in both laboratory and home environments.
• Strong correlations were observed between OCPT scores obtained in laboratory and home settings.
• Significant performance differences on the OCPT were identified between children with and without ADHD across both settings.

Conclusions:

• The OCPT is a reliable and valid instrument for assessing children's attention.
• The OCPT shows promise as an effective tool for evaluating attention function in naturalistic settings.
• This online test offers a flexible and accessible method for cognitive assessment in pediatric populations.
