The Adult ADHD Self-Report Scale (ASRS-v1.1) is a globally recognized screening tool designed by the World Health Organization to identify and quantify symptoms of neurodivergence in adult populations. While childhood presentations often center on overt behavioral disruptions, adult ADHD frequently manifests as internal restlessness, chronic executive dysfunction, and emotional dysregulation. By offering a standardized symptom count mapped directly to foundational diagnostic criteria, this instrument provides a critical anchor during the often complex differential diagnosis process.

For clinicians, distinguishing underlying attentional deficits from overlapping clinical presentations is a frequent challenge. Symptoms like poor concentration or persistent fatigue can easily be misattributed when professionals evaluate coping strategies or assess patients who are experiencing burnout. The ASRS-v1.1 mitigates this ambiguity by clarifying the specific nature of the functional deficits. Mapping these symptoms accurately helps clinicians determine appropriate therapeutic interventions and clearly explain managing ADHD key skills to their patients.

Using this measure allows professionals to establish a reliable baseline of functional impairment before initiating pharmacological or behavioral treatments. It is also an invaluable asset when exploring how memory actually works with adults who misinterpret their working memory deficits as early cognitive decline. Incorporating the ASRS-v1.1 into routine intake batteries ensures a systematic and evidence-based approach to adult neurodevelopmental assessment.

Example result

Fictitious result, computed from a sample set of answers.

Self-report screening questionnaire for adult attention-deficit/hyperactivity disorder (ADHD) (aged 18 and older), developed by the World Health Organization (WHO) with an international Workgroup on Adult ADHD, based on the Composite International Diagnostic Interview and DSM-IV-TR criteria (consistent with DSM-5). The scale consists of 18 items: Part A (6 items) serves as the rapid screening tool (items most predictive of the diagnosis); Part B (12 items) provides additional clues and allows for a more detailed exploration of symptomatology (inattention and hyperactivity/impulsivity).

Fewer than four responses in the most predictive boxes of Part A: the criterion for a positive adult ADHD screen is not met. A non-positive screen does not replace clinical assessment when attentional difficulties are reported.
Hyperactivity and Impulsivity

Hyperactivity-impulsivity: 9 items (5, 6, 12 to 18) assessing motor restlessness, difficulty remaining seated, excessive talking, and impulsivity (interrupting, difficulty waiting one's turn).

What the test measures

The ASRS-v1.1 systematically evaluates the frequency and severity of core clinical symptoms over the past six months, directly reflecting established diagnostic parameters.

  • Inattention: Difficulties with sustaining focus, organizing tasks, following through on complex projects, and a tendency to make careless errors.
  • Hyperactivity: Physical restlessness, an internal sense of being driven by a motor, and the inability to remain seated or physically relaxed during downtime.
  • Impulsivity: Challenges with conversational turn taking, interrupting others, and an inability to wait patiently in social or professional settings.
  • Executive dysfunction: Chronic struggles with working memory, such as misplacing everyday items or forgetting obligations.

This instrument is validated for use with adult populations aged 18 and older in both primary care and specialized psychiatric settings.

When and why to use it

Integrating the ASRS-v1.1 into clinical practice provides a standardized method for detecting and monitoring specific symptoms in adults.

  • Initial psychiatric intake: To screen for underlying traits in adults presenting with chronic disorganization or academic underachievement.
  • Differential diagnosis: To separate primary executive dysfunction from secondary cognitive overload seen in generalized anxiety disorder or severe depressive episodes.
  • Comorbidity assessment: To clarify symptom overlap when assessing patients for complex presentations, such as bipolar disorder warning signs or specific personality disorders.
  • Treatment monitoring: To track fluctuations in symptom severity and evaluate the functional efficacy of prescribed interventions over time.

Using a validated dimensional measure transforms vague patient complaints of scattered focus into quantifiable data, grounding clinical decisions far more reliably than unstructured clinical impression alone.
