Adult ADHD Self-Report Scale (ASRS)

The Adult ADHD Self-Report Scale (ASRS) is a scientifically developed screening tool designed to identify symptoms commonly associated with Attention-Deficit/Hyperactivity Disorder (ADHD) in adults. Developed with support from the World Health Organization (WHO), the scale is widely used in mental health screening, research, and clinical assessment settings.

The ASRS consists of two sections: Part A and Part B. Part A contains 6 key screening questions that are considered the most predictive of adult ADHD symptoms. Part B includes additional questions that provide a broader understanding of attention difficulties, impulsivity, restlessness, organization problems, and everyday functioning challenges.

Participants rate how often they experience certain behaviors using response options such as Never, Rarely, Sometimes, Often, and Very Often. Higher scores may indicate stronger ADHD-related symptom patterns and functional difficulties.

Research has shown that the ASRS has good reliability and validity as an adult ADHD screening measure. Studies suggest that Part A has strong predictive accuracy for identifying individuals who may require further professional evaluation. However, the ASRS is a screening tool only and does not provide a clinical diagnosis. A complete diagnosis should be made by a qualified healthcare professional through comprehensive assessment and clinical evaluation.

You will be presented with a series of statements describing everyday behaviors and experiences. Read each statement carefully and select the response that best describes how often you experience the behavior in your daily life. Answer honestly and based on your typical experiences over recent months. There are no right or wrong answers.

This assessment is intended for adults who wish to explore patterns related to attention, focus, impulsivity, organization, and activity levels. Participation is voluntary and responses should reflect your genuine experiences for the most meaningful results.

Each response is scored on a 0–4 scale ranging from “Never” to “Very Often.” Higher scores indicate a greater frequency of ADHD-related behavioral patterns. Results are converted into percentage-based scores across multiple dimensions, including Attention Regulation, Organization, Memory, Hyperactivity, and Impulsivity. The final report provides a general overview of symptom tendencies and behavioral patterns.
