When diagnosing ADHD in young adults emphasize informant reports, DSM items, and impairment

Area of Science:

• Psychiatry
• Neurodevelopmental Disorders
• Clinical Psychology

Background:

• Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder.
• Diagnosis in young adulthood presents challenges due to symptom persistence and diagnostic criteria evolution.
• Understanding diagnostic accuracy is crucial for appropriate intervention.

Purpose of the Study:

• To examine the diagnostic accuracy of attention-deficit/hyperactivity disorder (ADHD) in young adults.
• To compare self-report versus informant ratings for current and childhood functioning.
• To evaluate the utility of adult-specific ADHD items versus Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria.

Main Methods:

• Utilized data from 200 young adults with childhood ADHD diagnoses and 121 controls.
• Assessed current and childhood functioning using self- and informant reports.
• Compared diagnostic utility of DSM-based items and adult-specific ADHD symptom measures.

Main Results:

• A majority of young adults with childhood ADHD reported persistent symptoms (75%) and impairment (60%).
• Only 9.6%-19.7% met full DSM-IV-TR criteria for ADHD in young adulthood.
• Parent reports were more sensitive than self-reports, with young adults tending to underreport symptoms.

Conclusions:

• Current ADHD diagnostic criteria may not fully capture persistent ADHD in young adults.
• Informant reports are vital for accurate ADHD assessment in this age group.
• Emphasis on functional impairment and cautious interpretation of retrospective reports are recommended for ADHD diagnosis.
