ADHD Mirror is a free, clinically-informed ADHD self-assessment tool for adults. Unlike standard ADHD quizzes, this assessment is based on the ASRS v1.1 Part A screening methodology developed by the WHO and Harvard Medical School — the same framework used by clinicians to screen for adult ADHD.
Most online ADHD tests use simple yes/no checklists. ADHD Mirror uses a two-tier scoring system that separately measures your core ADHD signal score and screens against the 7 highest-predictive questions from the Adult ADHD Self-Report Scale (ASRS). It also accounts for masking — the coping behaviours that cause many people with ADHD, particularly women, to score lower than their symptoms warrant.
The assessment covers inattentive symptoms, hyperactivity, impulsivity, emotional dysregulation, executive dysfunction, hyperfocus, and functional impairment. It also screens for overlapping conditions including anxiety, depression, sleep disorders, and burnout — all of which can look similar to ADHD or co-occur with it.
This free ADHD assessment is designed for adults who suspect they might have ADHD, have never been formally assessed, or feel that previous assessments did not capture the full picture. It is particularly useful for women with ADHD, people with inattentive ADHD (sometimes called ADD), and adults who have developed strong masking or coping strategies.
Your results include an overall ADHD likelihood rating (High, Moderate, or Low), a detailed breakdown across 7 symptom clusters, a personalised narrative based on your specific pattern of answers, and a downloadable GP summary you can take to your doctor to start the conversation about a formal ADHD assessment. The tool is completely free, takes approximately 5 minutes, and does not require an account or email address.
Common signs of ADHD in adults include difficulty concentrating on tasks, chronic disorganisation, forgetfulness, impulsivity, emotional dysregulation, time blindness, procrastination, and difficulty completing tasks even when motivated. Many adults with ADHD also experience hyperfocus — periods of intense concentration on things they find interesting — which can make ADHD harder to recognise.
Masking refers to the strategies people with ADHD develop to hide or compensate for their symptoms. This is particularly common in women and girls, who are socialised to appear organised and in control. High masking can cause ADHD assessments to underestimate the real impact of symptoms. ADHD Mirror accounts for masking as a separate factor and adjusts scores accordingly.
To get an ADHD diagnosis in the UK, speak to your GP first. Your GP can refer you to a psychiatrist or clinical psychologist for a formal assessment. ADHD Mirror generates a GP-ready summary to help you start that conversation.
No self-assessment tool can diagnose ADHD — only a qualified clinician can do that. However, this assessment uses the ASRS Part A screening methodology validated by the WHO and Harvard Medical School, which means it can tell you whether your experiences align with how ADHD typically presents in adults. Think of it as a meaningful starting point, not a verdict.
Masking is when a person with ADHD learns to hide or compensate for their symptoms — appearing organised or calm on the outside while struggling significantly on the inside. This is especially common in women, girls, and people diagnosed later in life. This tool treats masking as a separate factor and adjusts scores accordingly.
Most online ADHD quizzes use simple yes/no checklists with no clinical grounding. ADHD Mirror uses a two-tier scoring system based on the ASRS Part A screen, weighted by which symptom clusters are most predictive of ADHD in adults. It also separately assesses masking, emotional dysregulation, executive dysfunction, functional impairment, and screens for overlapping conditions like anxiety, depression, and burnout.
Yes. Women and girls are significantly underdiagnosed with ADHD, often because they present with inattentive symptoms and are more likely to mask effectively. This assessment is designed to be sensitive to these differences.
Start by speaking to your GP. You can download a GP-ready summary from this tool to bring to your appointment. Your GP can then refer you for a formal assessment with a psychiatrist or clinical psychologist who specialises in ADHD.
Yes. Many adults reach their 30s, 40s, or even later before receiving an ADHD diagnosis. Adult diagnosis is increasingly common and fully recognised by the NHS.
