What the Test Looks Like
The Core Components of a Professional Evaluation
When you finally sit down with a qualified professionalwhether thats a psychiatrist, a clinical psychologist, or an ADHDspecialistyou can expect three main ingredients:
- Diagnostic interview: A deepdive into your life story, from childhood school days to current work challenges.
- DSM5 criteria checklist: The DSM5 criteria for ADHD in adults require at least five symptoms of inattention or hyperactivityimpulsivity that have persisted since childhood and cause functional impairment.
- Standardized rating scales: Tools like the Adult ADHD SelfReport Scale (ASRS), ConnersAdult, or the Brown Attention Scale give a quantified picture of your symptoms.
Whos In the Room?
Besides the clinician, youll often be asked to bring a collateral informantsomeone who sees you in another context, such as a spouse, partner, close friend, or even a coworker. Their perspective helps confirm whether symptoms show up across different settings, which is a key part of the diagnosis.
Sample Interview Flow (StepbyStep)
| Step | What Happens | Typical Time |

| 2 Initial Visit | Clinical interview, medical review | 3045min |
| 3 Rating Scales | Patient & informant complete questionnaires | 1015min each |
| 4 Optional Psychometrics | Continuous Performance Test or executivefunction batteries | 3060min |
| 5 Feedback Session | Results discussion, diagnosis, treatment plan | 2030min |
How Long Does It Take
Typical Timelines Across Settings
Timeframes can vary dramatically depending on where you seek help:
- Private practice: Usually 12weeks from first contact to diagnosis.
- NHS (UK): Waiting lists often mean 412weeks for a full assessment (NHS ADHD assessment).
Factors That Speed Up or Slow Down Diagnosis
Things that can make the process smoother:
- Using a reputable free screener before your appointment.
