Area of Science:

• Child and Adolescent Psychiatry
• Neurodevelopmental Disorders
• Psychological Assessment

Background:

• The Conners Continuous Performance Test II (CCPT-II) is widely used for diagnosing ADHD in children, despite lacking validation in Norwegian populations.
• Evidence regarding the CCPT-II's effectiveness in differentiating between children with and without ADHD is inconsistent.
• This study addresses the need for further validation of the CCPT-II in clinical practice.

Purpose of the Study:

• To examine the correlation between CCPT-II results and ADHD symptoms reported by mothers and teachers.
• To investigate the influence of CCPT-II findings on the diagnostic process for ADHD.
• To assess the utility of the CCPT-II in a representative sample of child and adolescent mental health services.

Main Methods:

• The study analyzed correlations between CCPT-II performance and ADHD Rating Scale scores in 69 children aged 6-15 years.
• Participants were referred to a child and adolescent psychiatric outpatient clinic.
• Statistical analyses were performed to compare CCPT-II results between children with and without ADHD.

Main Results:

• Maternal ADHD symptom ratings showed small to moderate correlations with several CCPT-II measures, including reaction time and overall index.
• Teacher ratings of ADHD symptoms correlated with commission errors and variability.
• Children diagnosed with ADHD exhibited a significantly higher number of commission errors on the CCPT-II compared to controls.

Conclusions:

• Correlations between CCPT-II results and ADHD symptoms were generally small to moderate.
• The CCPT-II's correspondence with other ADHD assessment measures is limited.
• Findings suggest that CCPT-II results should be interpreted with caution in clinical practice.
