World Health Organization Disability Assessment Schedule 2.0 - 12 item
WHODAS 2.0 12-item is a World Health Organization functioning measure. This page is for clinics. It is not a diagnosis and not a public test.
Overview
What is the WHODAS 2.0?
The WHO Disability Assessment Schedule 2.0 measures difficulties in day-to-day functioning across domains such as mobility, self-care, and participation. The 12-item form is a short version of a longer 36-item instrument. Functioning is not the same construct as a symptom total.
Development and clinical use
WHO published WHODAS 2.0 as a generic functioning measure linked to the ICF. 12-item and 36-item versions, plus interviewer and self-administered modes, exist. Mixing them without naming the version undermines change scores.

Administration
A focused client experience
The person, or an interviewer, completes the authorised 12-item form about recent functioning. Results support treatment planning and review. They do not replace diagnosis or capacity assessments your clinic may run separately.
- 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
The illustration does not reproduce WHODAS items.

Methodology
Understand the measure and its scoring conventions
WHO manuals describe scoring for 12-item and 36-item versions. This page does not independently verify a production scoring rule. Use the official 12-item materials if that is the form you mean.

Questions
What clinics ask before they evaluate the WHODAS 2.0
These answers stay inside educational catalogue scope. They do not replace official manuals or clinician judgement.
Is this the 36-item WHODAS?
No. This catalogue entry is the 12-item form. Do not apply 36-item scoring to it.
Does WHODAS diagnose disability legally?
No. It is a functioning measure for clinical review, not a benefits or legal determination.
Can I complete it here?
No. This landing does not collect answers.
Why use functioning as well as symptoms?
People with similar symptom totals can function very differently. WHODAS structures that second question.
