Weiss Functional Impairment Rating Scale - Self
WFIRS-S is a self-report of functional impairment often used in ADHD pathways. This page is for clinics. It is not a symptom screen and not a public test.
Overview
What is the WFIRS-S?
The Weiss Functional Impairment Rating Scale - Self asks about difficulties in domains such as family, work, school, life skills, self-concept, and social activity. Impairment is a different question from ASRS symptom frequency.
Development and clinical use
The WFIRS family was developed to capture ADHD-related functional impairment rather than symptom counts alone. Self and parent versions exist, and the materials are commonly distributed through CADDRA.

A focused client experience

- 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

Questions
What clinics ask before they evaluate the WFIRS-S
These answers stay inside educational catalogue scope. They do not replace official manuals or clinician judgement.
Is WFIRS-S the same as ASRS?
No. ASRS is a current-symptom screen. WFIRS-S asks about functional impairment.
Does WFIRS-S diagnose ADHD?
No. Impairment evidence still needs clinician interpretation.
Can I complete it here?
No. This page is educational catalogue information.
Which WFIRS form should a clinic use?
WFIRS-S for adult self-report and WFIRS-P for a parent informant. Name the form before any live digital workflow.
