World Health Organisation Disability Assessment Schedule (WHODAS II)

The WHODAS II has been developed to assess the activity limitations and participation restrictions experienced by an individual irrespective of medical diagnosis. Respondents are asked to state the level of difficulty experienced taking into consideration how they usually do the activity, including the use of any assistive devices and/or the help of a person. The domains included in the instrument are:
• Understanding and communicating
• Getting around
• Self care
• Getting along with people
• Life activities
• Participation in society

Several versions of the WHODAS II are available. These include interviewer administered versions, self-administered versions, and proxy versions. Varying lengths are also offered. All things being equal, we recommend the 36-item, interviewer-administered version because it provides the most complete profiling of respondents. If, due to time constraints and/or study design, it is not feasible to utilise a 36-item interviewer-administered version, other versions are good alternatives.
