ADHDtest.ai
ADHDtest.ai is an online ADHD screening platform for adults who want structured evidence before pursuing a formal diagnosis. You complete a multi-section questionnaire aligned with DSM-5 criteria, then get an instant likelihood indicator across inattention, hyperactivity, and executive function domains. The service was established in 2023 and has completed more than 2,350 assessments.
The assessment battery combines three validated psychometric instruments: the ASRS-v1.1 (WHO Adult ADHD Self-Report Scale), the Brown Attention-Deficit Disorder Scales (BADDS), and the Wender Utah Rating Scale (WURS-25) for childhood symptom history. An analysis layer cross-references scores across 86 data points and screens for comorbid conditions such as anxiety, depression, and sleep disorders, following WHO guidance that ADHD should not be evaluated in isolation.
Clinical content is developed under supervision of HCPC-registered psychologists and licensed counselors, including Adeel Sarwar (DClinPsy) and Dr. Marc Mandell (LPCC). Reports are designed as supporting documentation for GP or psychiatrist appointments, not as a replacement for a qualified clinician's diagnosis.
The platform also hosts separate online tests for anxiety, depression, bipolar disorder, BPD, OCD, PTSD, and other mental health conditions. The interface is available in English, German, Spanish, French, Portuguese, and Danish.

Is ADHDtest.ai free to use?

What is the difference between the ADHD Report and Pro Assessment on ADHDtest.ai?
The ADHD Report on ADHDtest.ai costs $9.99 as a one-time payment and delivers a downloadable PDF with scores, symptom breakdown, and clinical scale results. The Pro Assessment costs $49.99 and adds an AI-generated clinical narrative, executive function profile, comorbidity screening indicators, coping strategies, and next-step recommendations.
Is ADHDtest.ai a clinical diagnosis?
No. ADHDtest.ai provides validated screening tools, not a formal clinical diagnosis. Only a qualified healthcare professional such as a psychiatrist or clinical psychologist can diagnose ADHD. The reports are designed as structured evidence you can bring to a diagnostic appointment.
How long does the ADHDtest.ai assessment take?
The full ADHDtest.ai assessment takes between 30 and 60 minutes across multiple sections covering current symptoms, childhood behavior, executive function, and optional comorbidity screening. You can save progress and return later to finish.
What clinical scales does ADHDtest.ai use?
ADHDtest.ai uses the ASRS-v1.1 (WHO Adult ADHD Self-Report Scale) for current symptom screening, the Brown Attention-Deficit Disorder Scales (BADDS) for executive function profiling across six domains, and the Wender Utah Rating Scale (WURS-25) for retrospective childhood symptom assessment.
Can I use an ADHDtest.ai report for an NHS referral or GP visit?
Many ADHDtest.ai users take the Pro Clinical Report to their GP or psychiatrist as supporting evidence. The report includes standardized scale scores, a DSM-5-aligned symptom profile, and a clinical narrative, though healthcare professionals are not obligated to accept third-party screening results.
Does ADHDtest.ai offer refunds?
ADHDtest.ai does not offer refunds once a paid report has been accessed because reports are generated and delivered digitally within minutes. For technical issues preventing report delivery, contact [email protected].
