WHO Disability Assessment Schedule 2.0 WHODAS 2.0


Frequently Asked Questions

What makes the WHODAS 2.0 different from other measures ?

A unique feature of WHODAS 2.0 is its direct link to the ICF, it was developed on the basis of an extensive cross-cultural study, spanning 19 countries across the world. It has excellent psychometric properties. Test–retest studies of the 36-item scale in countries across the world found it to be highly reliable. All items were selected on the basis of item–response theory. It is easy to use, can be self-administered in around 5 minutes, and administered through an interview in 20 minutes. It measures similar constructs as in other measures such as Short Health Survey. But it also measures day-to-day day functioning across a range of activity domains. Although other generic instruments for assessing health status can also be mapped to ICF, they do not clearly distinguish between measurement of symptoms, disability and subjective appraisal.

Is the WHODAS 2.0 different from WHO/DAS (1988) ?

Yes. The original Disability Assessment Schedule WHO/DAS-published by WHO in 1988 – was an instrument developed to assess functioning, mainly in psychiatric inpatients. Since then, the instrument has undergone considerable revision by the WHO Collaborating Centre at Groningen in The Netherlands, and been published as the “Groningen Social Disabilities Schedule” WHODAS 2.0 is an altogether different instrument that has been developed specifically to reflect the ICF.
