Adult ADHD Self Report Scale - 5 (ASRS-5)
What it is
The ASRS-5 is a short and easy-to-complete questionnaire designed to screen for symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) in adults. Developed in line with the DSM-5 criteria, this tool helps identify whether someone might be experiencing common signs of adult ADHD — such as trouble focusing, being easily distracted, struggling to stay organized, or acting impulsively.
While it doesn’t provide a diagnosis on its own, the ASRS-5 is a widely trusted first step in recognising patterns of attention and behaviour that could benefit from further clinical assessment.
How is it used
The ASRS-5 is suitable for adults aged 18 and older. It’s quick to fill out, usually taking around 5 minutes or less. The questions focus on how often someone experiences certain behaviours, such as trouble concentrating, forgetting tasks, or feeling restless. The ASRS-5 is commonly used in healthcare settings, during therapy, or even by individuals who are curious about whether their challenges might be related to ADHD. While it’s not a standalone diagnostic tool, it’s a great way to start conversations with a healthcare professional about whether a deeper assessment might be needed.
What do the scores mean?
The ASRS consists of 6 questions, with each question rated on a scale from 0 (never) to 4 (very often). The questionnaire is divided into two parts: 1. The first 6 questions (Part A) focus on the most predictive symptoms of adult ADHD. These are known as the “screening questions.” A higher score in this section is a strong indicator that ADHD may be present. 2. The remaining 12 questions (Part B) assess additional symptoms that can support the diagnosis.
The scoring is straightforward:
- For each question, a score of sometimes, often, or very often is considered significant.
- If a person scores in the significant range on 4 or more of the 6 questions, it’s a sign that further evaluation for ADHD might be beneficial.
What does the research say?
The ASRS was developed in collaboration with experts from the World Health Organization (WHO), ensuring that it’s a reliable tool backed by scientific research. It’s been shown to be both reliable (meaning it consistently measures symptoms accurately) and valid (meaning it accurately identifies ADHD in adults).
The ASRS is especially helpful because ADHD can sometimes be harder to recognize in adults. It’s a practical tool that helps identify symptoms that might have been overlooked, providing a structured way for adults to reflect on their experiences.
Note: The ASRS is a screening tool, not a diagnosis. If someone’s responses suggest ADHD, it’s important to consult with a healthcare professional for a comprehensive assessment.
