What diagnostic tools are used?

Validated tools support the clinical interview. They do not replace it. Diagnosis is always a clinical judgement made by your clinician, drawing on multiple sources of evidence.

QbCheck and QbTest

Computerised objective tests of attention and activity. They measure focus, impulsivity, and movement during a structured task. Results are compared with age-matched norms and read alongside the clinical interview.

DIVA-5

The Diagnostic Interview for ADHD in adults, version five. A structured interview that maps current and childhood symptoms onto recognised diagnostic criteria. It is widely used internationally and considered the gold standard for adult ADHD interview.

Rating scales and questionnaires

Validated self-report and observer-report scales such as the Adult ADHD Self-Report Scale and Conners scales. These help quantify symptoms and impact.

Collateral history

Where appropriate, your clinician may ask for input from a partner, parent, or teacher to triangulate the clinical picture. This is especially useful when childhood history is incomplete.

Your clinician chooses the tools most relevant to your case. Not every assessment uses every tool.
