The IDRlabs ADHD Spectrum Test (IDR-ADHDST) was developed by IDRlabs. The IDR-ADHDST is based on the work of Dr. Lenard Adler and his colleagues, who created the ADHD Adult Self-Report Scale (ASRS). The IDR-ADHDST is not associated with any specific researchers in the field of psychopathology or any affiliated research institutions.

The IDRlabs ADHD Spectrum Test was informed by the ASRS’ criteria for attention-deficit/hyperactivity disorder, as published in Kessler RC, Adler L, Ames M, Demler O, Faraone S, Hiripi E, Howes MJ, Jin R, Secnik K, Spencer T, Ustun TB, Walters EE. The World Health Organization Adult ADHD Self-Report Scale (ASRS): a short screening scale for use in the general population. Psychol Med. 2005 Feb;35(2):245-56. doi: 10.1017/s0033291704002892. PMID: 15841682; Adler LA, Spencer T, Faraone SV, Kessler RC, Howes MJ, Biederman J, Secnik K. Validity of pilot Adult ADHD Self-Report Scale (ASRS) to Rate Adult ADHD symptoms.

The work of Dr. Adler and his colleagues has also informed some of the diagnostic criteria in the form of the widely used psychological instrument, the ASRS, for clinical use, especially by qualified mental health professionals. The present test is intended for educational purposes only. IDRlabs and the present IDRlabs ADHD Spectrum Test are independent of the above researchers, organizations, or their affiliated institutions.

The ADHD Spectrum Test is based on a famous and well-regarded inventory for the assessment of the clinical concept of ADHD spectrum and other psychotic disorders. However, free online tests and quizzes such as this one are solely first takes and cannot provide accurate assessments of your potential condition. Hence, the test is intended to be used for educational purposes only. A definitive mental health assessment can be made only by a qualified mental health professional.

As the publishers of this free online ADHD spectrum test, which allows you to screen yourself for the signs and symptoms of this condition, we have strived to make the test as reliable and valid as possible by subjecting it to statistical controls and validation. However, free online quizzes such as the present ADHD spectrum test do not provide professional assessments or recommendations of any kind; the test is provided entirely “as-is.” For more information about any of our online tests and quizzes, please consult our Terms of Service.
