Evaluating Adults for ADHD: Essential Questions to Ask

When evaluating adults for ADHD, you must conduct a comprehensive psychiatric interview that specifically focuses on core ADHD symptoms beginning in childhood, obtain detailed substance abuse history, and critically, gather collateral information from a spouse, parent, or significant other—because adults with ADHD characteristically underestimate their symptoms and impairments 1.

Core Symptom Assessment

Childhood Onset Questions

  • Ask specifically about ADHD symptoms starting before age 7 (or age 12 per DSM-5 criteria). This is non-negotiable for diagnosis 1.
  • Obtain information from parents or siblings about childhood functioning, as retrospective self-reports are unreliable 2, 3.
  • Use structured tools like the Wender Parent's Rating Scale or Wender Utah Rating Scales to systematically assess childhood symptoms 1.

Current Symptom Inquiry

Focus on these specific domains:

  • Concentration problems and inattention
  • Impulsivity and poor impulse control
  • Poor anger control
  • Job instability and work performance issues
  • Marital difficulties and relationship problems 1

Critical Collateral Information

This is where most evaluations fail: Adults with ADHD have "notoriously poor insight" and systematically underestimate their symptoms 1. Research confirms that young adults with ADHD underreport current symptoms while those without ADHD overreport them 2.

  • Always obtain information from a spouse, significant other, parent, or close friend 1
  • Parent report is more diagnostically sensitive than self-report 2
  • There may be no significant benefit to combining self-report with informant report beyond informant report alone 2

Substance Abuse History

Because of the high comorbidity rate, you must obtain a detailed drug and alcohol history 1:

  • Current and past substance use patterns
  • Consider obtaining a urine drug screen 1
  • Assess for substance use disorders that may mimic or complicate ADHD

Functional Impairment Assessment

DSM criteria require impairment in at least two realms 3:

  • Home functioning
  • School/work performance
  • Social interactions

Ask specific questions about:

  • Job changes, terminations, or chronic underperformance
  • Relationship instability
  • Financial management problems
  • Daily task completion difficulties

Differential Diagnosis Questions

Rule out conditions that masquerade as ADHD 1:

  • Bipolar disorder: Ask about mood episodes, grandiosity, decreased need for sleep
  • Depression: Assess for anhedonia, guilt, suicidal ideation
  • Anxiety disorders: Distinguish from generalized anxiety, social phobia
  • Personality disorders (especially Axis II disorders)
  • Learning disabilities: Obtain educational history
  • Narcolepsy: Ask about irresistible sleep attacks
  • Borderline intellectual functioning: Review educational and occupational history
  • Medical conditions: Thyroid disorders, sleep apnea, neurological conditions

Structured Assessment Tools

Use validated rating scales 1:

  • Wender Parent's Rating Scale (for childhood symptoms)
  • Wender Utah Rating Scales
  • Brown Attention-Deficit Disorder Scale for Adults
  • Conners Adult ADHD Rating Scale

Important caveat: While behavior rating scales alone have adequate sensitivity, they have poor specificity 4. DSM-IV items are more predictive of diagnostic group membership than adult-specific non-DSM items 2.

Medical History Components

  • Complete medical history and physical examination
  • Screening laboratory tests to rule out medical mimics 1
  • Medication history (some medications cause attention problems)
  • History of head injury or neurological illness

Common Pitfalls to Avoid

  1. Relying solely on self-report: This is the most critical error. Adults with ADHD lack insight into their deficits 1.

  2. Missing childhood onset: ADHD by definition begins in childhood. Adult-onset "ADHD" symptoms suggest another diagnosis 1.

  3. Overlooking substance abuse: High comorbidity rates make this essential to assess 1.

  4. Ignoring functional impairment: Symptoms without impairment don't meet diagnostic criteria 3.

  5. Failing to rule out bipolar disorder: This is frequently misdiagnosed as ADHD in adults 1.
