What to Expect From an Adult ADHD Assessment
Getting assessed for ADHD as an adult can feel like a big step. Whether you've suspected for years or only recently started connecting the dots, knowing what to expect can help ease some of the uncertainty.
Before the assessment
Most providers will send you questionnaires to complete before your appointment. These typically include standardised screening tools like the DIVA (Diagnostic Interview for ADHD in Adults) or the Conners Adult ADHD Rating Scales. You may also be asked to provide a developmental history — information about your childhood, school experience and family background.
Some providers will ask for a collateral history from someone who knew you as a child, such as a parent or sibling. This isn't always required, but it can strengthen the assessment.
During the assessment
The assessment itself is usually a structured clinical interview lasting between one and three hours, depending on the provider. A psychiatrist or specialist clinician will talk you through your symptoms, how they affect your daily life, and when they first appeared.
Expect questions about:
- Attention and focus — Do you struggle to concentrate on tasks? Do you frequently lose things or forget appointments?
- Hyperactivity and restlessness — Do you feel an internal sense of restlessness? Do you find it hard to sit still in meetings?
- Impulsivity — Do you make snap decisions? Do you interrupt people in conversation?
- Impact on daily life — How do these traits affect your work, relationships and wellbeing?
The clinician will also consider whether your symptoms might be better explained by another condition, such as anxiety or depression. This is a normal part of a thorough assessment.
After the assessment
You'll usually receive your results either on the day or within a few weeks, depending on the provider. If you receive an ADHD diagnosis, the clinician will discuss treatment options with you. These may include medication, therapy, coaching, or a combination.
If you're assessed through a private or Right to Choose provider, they'll typically write to your GP recommending a shared care agreement for ongoing prescribing and monitoring.
How to prepare
The best thing you can do is be honest and specific. Think about concrete examples of how ADHD traits show up in your life. It can help to keep a brief diary in the weeks leading up to your assessment, noting situations where you struggled with focus, organisation or impulsivity.
Remember: the assessment isn't a test you can pass or fail. It's a clinical evaluation designed to understand how your brain works, so you can get the right support.
