Top ADHD Tests and Quizzes on the Web

ADHD Quiz or ADHD Test, what’s the difference?

Only a healthcare professional can administer a test and assess you.  Online quizzes and tests will give you an idea if Attention Deficit Hyperactivity Disorder (ADHD or ADD) is something to consider, but they are not a replacement for a diagnosis.  In our video The Comprehensive Guide to ADHD we explain why a test is just one facet of a full ADHD diagnosis by a healthcare professional, and what to expect when you get an assessment.  Online quizzes and tests are meant as a starting point for you to explore ADHD.

This independently owned website (not funded by a pharmaceutical company) from Rick Green combines science and humor. Why that combination? As a former teacher at the Ontario Science Centre, Rick discovered that we all learn more easily when something is fun! Rick was diagnosed with ADHD of the combined subtype, at 47. Since then, he’s created the award-winning documentary ADD & Loving It?!, interviewed many of the world’s top ADHD experts, created TotallyADD, and scores of videos about many issues adults with ADHD face. An engaging speaker on the topic of adult ADHD, he has a skill for translating medical knowledge into things we can relate to and understand. Rick has developed this quick, easy, and reliable online ADHD Quiz with that in mind. The quiz is based on an ADHD screener, and is designed to help the user understand ADHD symptoms and which may be creating issues in everyday life.

Symptoms of ADHD

As Dr Steven Kurz told us for our documentary, ADD & Loving It?!; if you’ve seen one person with ADHD… You’ve seen one person with ADHD. The symptoms and severity are widely varied from person to person. Also, note that everyone has some of the Attention Deficit Hyperactivity Disorder symptoms. The difference for adults who have it is that the symptoms are seriously impairing, or ruining multiple areas of their life.

Is An ADHD Quiz Enough?

By now you may be wondering why there are so many tests, questionnaires, quizzes, and screeners available, and whether just taking one of them is enough for you. While it may give you lots of insight into what the symptoms of ADHD are, and whether or not you may be affected by it, only a health professional who is trained to diagnose ADHD can do that. And there’s value in knowing what your particular challenges are so that you are able to then deal with them. A trained health professional may use a quiz, or a screener as a starting point, but they have many more tools, including an interview, to help them make their assessment. For more information on rating scales and screeners, healthline has a comprehensive page listing commonly found rating scales, and what to look for.
