The following ADHD Self-Screening Test is designed to help identify whether you are experiencing common symptoms associated with Attention-Deficit/Hyperactivity Disorder (ADHD). This questionnaire is based on the World Health Organization's ASRS v1.1 tool and typically takes about 5 minutes to complete.

About this ADHD test

What is the ASRS v1.1 adult ADHD test?

The Adult ADHD Self-Report Scale (ASRS v1.1) is a screening questionnaire developed with the World Health Organization. It has 18 questions, based on the symptoms ADHD is diagnosed by, and asks how often each one has applied to you over the past six months.

The first six questions, Part A, are the screener. The research behind the scale (Kessler et al., 2005) found them the most predictive of ADHD in adults, and they are the only ones that are scored. The other twelve, Part B, are not scored. They give a clinician more detail to explore with you at an assessment.

Scoring

How the ADHD self-assessment is scored

Each question has five answers, from Never to Very Often. For each Part A question, some of those answers fall in a shaded range. Four or more answers in the shaded range is a positive screen: symptoms highly consistent with ADHD in adults, and a reason to arrange a full assessment.

A screening test can be wrong in both directions. Anxiety, low mood and poor sleep can cause similar difficulties, and some people who have ADHD score below the threshold. That is why NICE guidance (NG87) says ADHD should be diagnosed by a specialist after a full clinical assessment, and never on a rating scale alone.

Questions

ADHD test: common questions

No. An online ADHD test is a screening tool: it shows whether your answers fit a pattern often seen in adults who have ADHD. Only a specialist can diagnose ADHD, after a full clinical assessment. NICE guidance (NG87) says a diagnosis should not be made on a rating scale alone.

Yes. The test is free and takes about five minutes. You see your result straight away, on the same page, and you do not need to give your name or an email address to see it.

Yes. Your answers are stored without your name, email address or any other detail that identifies you, and with the date only, so we cannot link them to you. We only ever hold your answers with your name if you choose to send them to us yourself.

Four or more Part A answers in the shaded range is a positive screen. It means your symptoms are highly consistent with ADHD in adults, and that a full assessment is worth arranging. It is not a diagnosis.

A low score makes ADHD less likely on this screener, but it does not rule it out. Other things can also cause problems with attention, organisation and restlessness. If these difficulties affect your work, study or relationships, contact us or speak to your GP.

Adults aged 18 and over. The ASRS is an adult self-report scale, so it is not suitable for children. ADHD in a child or young person is assessed differently, with information from parents and school.

You see your Part A score, what it means and which of your answers were in the shaded range. You can print the report or save it as a PDF to take to an appointment or to your GP. If the result is positive, the next step is a full assessment.
