Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist
The ASRS v1.1 structures how often current adult ADHD-related experiences occurred over the past six months. This page is for clinics evaluating the measure on Lirena. It is not a questionnaire to complete here.
Overview
What is the ASRS?
The Adult ADHD Self-Report Scale v1.1 was developed with the World Health Organization and the Harvard Medical School National Comorbidity Survey team. The full checklist contains 18 self-report items, with a six-item Part A screener selected for its performance against clinician assessment.
Development and clinical use
The ASRS v1.1 was introduced in the early 2000s as an adult ADHD screening measure aligned to the symptom framework used at that time. Subsequent validation and normative studies have examined the six-item screener, the full checklist, and symptom burden in large adult samples.

Administration
A focused client experience
Respondents rate how often each experience occurred over the past six months using five frequency options. Results are intended to support a structured clinical conversation about current symptoms, functional impact, developmental history, collateral evidence, and differential diagnosis.
- One question at a time with visible progress
- Large keyboard-operable response choices
- Previous, next, and answer-review steps
- Clear confirmation that results go to the clinic
Response options are presented in a calm, focused layout with progress and review controls.

Methodology
Understand the measure and its scoring conventions
Lirena presents the complete 18-item ASRS-v1.1 Symptom Checklist. Part A, items 1 to 6, is the screener: the screen is positive when 4 or more Part A responses fall in the darkly shaded range, which is Sometimes or more for items 1 to 3 and Often or more for items 4 to 6. Lirena also reports the Part A total, the six responses scored 0 to 4 and summed to a range of 0 to 24 (Kessler et al., 2007). Part B, items 7 to 18, is shown for clinician review without a total, as the WHO form directs.

Questions
What clinics ask before they evaluate the ASRS
These answers stay inside educational catalogue scope. They do not replace official manuals or clinician judgement.
What is the ASRS used for?
The ASRS is an adult self-report screen for current ADHD-related symptom frequency. Clinics use it to structure that account before a clinician reviews developmental history, impairment, collateral evidence, and differential diagnosis.
Does a completed ASRS diagnose ADHD?
No. The ASRS is a screening instrument, not a standalone diagnostic test. A score cannot establish ADHD, presentation, impairment, onset, pervasiveness, or differential diagnosis without clinician-led assessment.
Can I take the ASRS on this page?
No. This is an educational catalogue landing and product showcase. Lirena does not offer a public self-test, automated interpretation, or treatment recommendation from this page.
Which ASRS form does Lirena present?
Lirena presents the complete 18-item ASRS-v1.1 Symptom Checklist. Its first six items are the Part A screener, so the clinician sees the Part A screen and the Part A total alongside the twelve Part B responses.
What does the example PDF show?
The downloadable file is a synthetic four-page layout using an invented response pattern. It shows how the Part A screen, the Part A total and the Part B responses are presented for review. It contains no patient data.
