Adult ADHD Screening Standards
This ADHD screening for adults uses the Adult ADHD Self-Report Scale (ASRS), a recognised screening tool used internationally to identify patterns of ADHD symptoms in adults. The ASRS screening test is widely used in clinical settings and is designed to support informed conversations between individuals and qualified clinicians.
While this ASRS test online can help highlight possible ADHD traits, it is intended as a screening tool only and does not provide a diagnosis. Any formal diagnosis requires a structured clinical assessment carried out by a qualified professional.
