The Adult ADHD Self-Report Scale (ASRS) is a brief questionnaire developed by the World Health Organization to help identify symptoms that may be consistent with Attention Deficit Hyperactivity Disorder. It is not a diagnostic tool on its own, but it can highlight patterns that deserve further evaluation by a qualified professional. The six questions above form "Part A" of the ASRS, which research has shown is particularly effective for initial screening.
Each question is scored from 0 to 4 based on how often you experience the described symptom, from "Never" to "Very Often." Four or more responses scored in the "Often" or "Very Often" range generally suggest that ADHD may be present. Mathematically we can represent each question response as a variable . The total score is . Because some questions carry more weight than others, mental health professionals typically focus on how many items fall in the top two frequency categories rather than the exact sum.
If your score indicates frequent struggles in several areas, consider discussing the results with a clinician experienced in ADHD assessment. They may perform additional interviews or gather reports from family or teachers to make a formal diagnosis. Even if you do not meet the threshold, the exercise can reveal patterns of inattention or hyperactivity that affect daily life. Many people benefit from organizational strategies, behavioral therapy, or, in some cases, medication to manage symptoms.
This calculator does not replace a comprehensive clinical evaluation. Stress, anxiety, and other medical conditions can mimic ADHD symptoms. Only a professional can determine the cause and appropriate treatment. Still, self-assessments like the ASRS offer a starting point for self-awareness and conversation. Repeating the questionnaire over time may help you monitor how symptoms change with lifestyle adjustments, therapy, or medication.
The ASRS is a quick tool to gauge whether your experiences align with common symptoms of adult ADHD. It empowers you to reflect on patterns of inattention and hyperactivity that might otherwise seem like personality quirks. Use the results to inform discussions with a healthcare provider and to explore strategies for improving focus and managing impulsivity.
