ASRS v1.1
A screening tool for adult ADHD developed with the WHO.
What is it?
The ASRS v1.1 (Adult ADHD Self-Report Scale) was developed by a World Health Organization working group. It comprises 18 questions inspired by the DSM criteria for ADHD.
The first 6 questions (Part A) form the main screen: they are the most predictive. The other 12 (Part B) provide complementary insight.
Why it is used
Part A is calibrated with different thresholds depending on the question. You count the number of responses falling within the "significant zone": from 4 responses out of 6, the screen is positive and points toward an in-depth assessment.
It is one of the most widely used screening tools for adult ADHD, being short and validated.
Its limits
A positive screen is not a diagnosis. Many factors (sleep, stress, anxiety, depression) mimic the symptoms of ADHD. The diagnosis rests on a specialist assessment, including the developmental history.
