Does the Continuous Performance Test Predict ADHD Symptoms Severity and ADHD Presentation in Adults?

Abstract

<b>Objective:</b> Our study aimed to provide empirical evidence on the usefulness of one of the most popular neuropsychological tests, the Continuous Performance Test (CPT), as a marker of ADHD severity and presentations among adults. <b>Method:</b> ADHD participants were recruited in a specialized center for the diagnosis and treatment of adults suffering from ADHD (<i>n</i> = 201). Measures included the CPT3™ and ADHD symptoms using a clinical interview and self-reported measures. <b>Results:</b> Only 51.7% of the participants were classified as likely to have a disorder characterized by attention deficit, such as ADHD, by the CPT. The relationships between CPT variables and ADHD symptoms were small. The classification error was 80.3% for the inattentive presentation and 22.5% for the hyperactive presentation when using the CPT to identify ADHD presentations. <b>Conclusion:</b> There was no evidence of the clinical utility of the CPT to assess or monitor ADHD in adult populations diagnosed and treated for ADHD.
