The Other ADHD Tests Nobody Tells You About
Share
Most people who dig into ADHD testing come across WURS (Wender Utah Rating Scale) pretty quickly.
It’s a good starting point, especially because it looks back at childhood symptoms – something a lot of adult ADHD assessments forget about.
But here’s the thing: WURS is just one piece of the puzzle.
If you’re serious about understanding ADHD in adults (for yourself or someone close), there are other tools that add context, detail and accuracy.
Let’s go through them in plain language.
1. ASRS – the quick screener
The Adult ADHD Self-Report Scale is the one most people start with. It was developed by the World Health Organization (WHO) together with Harvard, and it’s basically a two-part form:
-
Part A – 6 questions. This is the short screener.
-
Part B – 12 more questions if you want to go deeper.
It looks at the last 6 months of your life. It’s not about childhood – it’s about right now.
The nice thing? It’s free, fast (5 minutes), and honestly, if you only do Part A you already get a decent indication of whether it’s worth investigating further.
2. CAARS – when you need more detail
Conners’ Adult ADHD Rating Scales is like the grown-up version of a microscope.
It comes in two flavours: you fill one in yourself and someone who knows you well (partner, friend, parent) fills in the observer form.
It’s broken down into subscales for things like inattention, hyperactivity, impulsivity, emotional swings, etc.
This one is more clinical – think detailed, norm-referenced, very data-heavy.
3. BAARS-IV – Barkley’s approach
Russell Barkley is one of the top researchers in ADHD, so it’s no surprise his test gets used a lot.
BAARS-IV (Barkley Adult ADHD Rating Scale) digs into:
-
Your childhood symptoms (so you’re looking back)
-
Your current symptoms (right now)
It’s very focused on the timeline – when things started, whether they’ve stuck around, and how they show up today.
If you like things clear and structured, this one is solid.
4. DIVA-5 – the interview
This one’s different.
DIVA-5 (Diagnostic Interview for ADHD in Adults) isn’t a questionnaire you take home. It’s an interview done by a trained clinician.
The big advantage is that it’s conversational. The clinician walks you through real-life examples of each symptom, in both childhood and adulthood, and helps you make connections that you might miss in a checklist.
A lot of clinics in Europe consider DIVA-5 the gold standard for adult ADHD diagnosis.
5. Brown ADD Scales – executive function focus
This one is a bit of a curveball because it’s not just about ADHD symptoms as listed in the DSM.
It looks at how your brain actually handles daily life:
-
Getting started on tasks
-
Staying focused
-
Following through
-
Managing emotions
-
Keeping things in working memory
If your biggest struggle is organisation, procrastination, planning or emotional regulation, the Brown ADD Scales might reveal what the basic checklists don’t.
How they fit together
Here’s the simplest way to think of these:
-
WURS – looks at your childhood.
-
ASRS – quick snapshot of right now.
-
CAARS / BAARS-IV – deep dive into symptoms and how severe they are.
-
DIVA-5 – structured conversation with a professional.
-
Brown ADD – zooms in on executive function.
Most clinics will mix and match these rather than relying on just one.
Why this matters
If you’re exploring ADHD, whether for yourself or someone else, it helps to know that there isn’t one single magic test.
Each of these tools gives a different perspective. Together, they form a fuller picture.
And just to be super clear: self-tests are for guidance. They’re not a diagnosis.
The real clarity comes when you take these results to a clinician who knows how to read them in context.
