Assessing adult ADHD using a self-report symptom checklist

Area of Science:

• Psychiatry
• Neurodevelopmental Disorders
• Clinical Psychology

Background:

• Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that can persist into adulthood.
• Accurate diagnosis in adults is crucial for effective management and treatment.
• Self-report measures are commonly used in ADHD assessment.

Purpose of the Study:

• To compare self-ratings of DSM-IV ADHD symptoms in adults with a previous ADHD diagnosis versus age- and sex-matched controls.
• To evaluate the diagnostic utility of DSM-IV ADHD criteria in adult populations.

Main Methods:

• Adults with a prior ADHD diagnosis and a control group completed self-rating scales for DSM-IV ADHD symptoms.
• Statistical analyses were performed to contrast symptom endorsement between the two groups.
• Predictive power analysis was used to assess the likelihood of a prior diagnosis based on symptom endorsement.

Main Results:

• Adults previously diagnosed with ADHD endorsed significantly more symptoms of inattention and hyperactivity-impulsivity compared to controls.
• 13 out of 18 DSM-IV ADHD symptoms were endorsed more frequently by the ADHD group.
• High likelihood of a prior ADHD diagnosis was found in individuals endorsing ADHD symptoms.

Conclusions:

• Self-reported DSM-IV ADHD symptoms effectively differentiate adults with a previous diagnosis from controls.
• The DSM-IV criteria requiring 6 symptoms of inattention or 6 symptoms of hyperactivity-impulsivity appear applicable for adult ADHD assessment.
• These findings support the validity of self-report symptom ratings in adult ADHD diagnosis.
