Evidence-Based Assessment for Attention-Deficit/Hyperactivity Disorder.

Area of Science:

• Neurodevelopmental Disorders
• Psychiatry
• Public Health

Background:

• Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder impacting diverse populations across the lifespan.
• Undiagnosed ADHD leads to significant public health costs, complicated by high comorbidity and symptom evolution over time.
• Accurate and equitable ADHD assessment is crucial for effective intervention and mitigating negative outcomes.

Purpose of the Study:

• To outline best-practice recommendations for evidence-based ADHD assessment.
• To address the complexities of ADHD diagnosis across different age groups and demographic factors.
• To identify areas for future research in ADHD assessment validity and application.

Main Methods:

• Predictive analysis of existing ADHD assessment literature and guidelines.
• Synthesis of recommendations for incorporating various rating scales (ADHD-specific, broadband) and informant types.
• Consideration of cognitive factors like IQ, academic achievement, and executive function in assessment protocols.

Main Results:

• Recommended ADHD assessment integrates ADHD-specific and broadband rating scales from multiple informants.
• Assessment strategies should adapt based on age: averaging parent/teacher ratings for children under 12.
• For adolescents and adults, informant reports are prioritized over self-reports when discrepancies exist.

Conclusions:

• Evidence-based ADHD assessment necessitates a multi-informant approach tailored to developmental stage.
• Further research is needed to validate assessment tools for treatment response, developmental changes, and underrepresented populations.
• Enhancing ADHD assessment accuracy across all demographics is vital for improving public health outcomes.
