About the ADHD Test (ASRS-18)

The ADHD Test available on this platform uses the ASRS-v1.1 (Adult ADHD Self-Report Scale), developed by experts from the World Health Organization (WHO).

It is considered the international gold standard for initial screening of Attention-Deficit/Hyperactivity Disorder in adults due to its high sensitivity and correlation with clinical diagnoses.

Origin and Development

The ASRS was created by the World Health Organization's Workgroup on Adult ADHD, led by renowned researchers like Ronald C. Kessler (Harvard Medical School). The goal was to create a short, effective tool that could be used outside of a clinical setting to identify adults who might benefit from a full medical evaluation.

Understanding Profiles: ADD vs ADHD

Many people arrive at the test wanting to know if they have "just ADD" or ADHD. Currently, medicine classifies everything under the ADHD umbrella, but with distinct presentations that the ASRS test helps identify:

Predominantly Inattentive

Characterized by difficulty focusing, disorganization, forgetfulness, and procrastination. Less physical agitation, more "daydreaming". Common in adults and women.

Hyperactive / Impulsive

Marked by restlessness, difficulty sitting still, excessive talking, and acting without thinking. In adults, it often manifests as an internal sense of "motor running".

Combined Presentation

The most common type. The individual presents significant criteria of both inattention and hyperactivity/impulsivity, affecting various areas of life.
