The Adult ADHD Self-Report Scale (ASRS-5) – Free Test


The ASRS-5 is a concise screening tool used to identify symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) in adults. It is a shorter version of the original ASRS, developed by the World Health Organization (WHO) in collaboration with the Workgroup on Adult ADHD.



The ASRS-5 is intended to help individuals and healthcare professionals quickly determine the likelihood of ADHD in adults. It is not a diagnostic tool but rather a preliminary screening to identify those who may need a more comprehensive evaluation.


The ASRS-5 consists of six questions derived from the DSM-5 criteria for ADHD. These questions assess the frequency of symptoms related to inattention, hyperactivity, and impulsivity over the past six months.

Questions and Scoring

Each question is rated on a five-point scale:

  • 0 = Never
  • 1 = Rarely
  • 2 = Sometimes
  • 3 = Often
  • 4 = Very Often


What it Measures:

  • The ASRS-5 focuses on symptoms experienced in the past six months.
  • It assesses two core ADHD categories through six questions:
    • Inattention: Difficulty focusing, concentrating, and staying on task.
    • Hyperactivity-Impulsivity: Restlessness, fidgeting, and blurting out responses.

Test Format:

  • The ASRS-5 consists of six short questions.
  • Each question uses a five-point Likert scale, ranging from “Never” (0) to “Very Often” (4).


  • While the test may be available online, it’s primarily used by healthcare professionals.
  • They might administer it during an initial assessment or to support a referral for a more comprehensive ADHD evaluation.

Important Considerations:

  • Screening Tool, Not Diagnosis: A high score suggests potential ADHD but doesn’t confirm it. Conversely, a low score doesn’t rule it out entirely.
  • Follow-Up: If your score suggests ADHD, discuss it with your doctor or a mental health professional for a comprehensive evaluation.
  • Accuracy: Relies on honest self-reporting.
  • External Factors: Medications or mental health conditions can influence answers. Disclose relevant health information to your doctor.
  • Target Population: Intended for adults 18 years and older.
