Name of the instrument

World Health Organization Disability Assessment Schedule

Abbreviation

WHODAS 2.0

Number of items

12

Terms of use

Public domain. While the instrument is in the public domain and free of charge, an online registration form must be completed before it is used: http://www.who.int/classifications/icf/whodasii/en/.

Language

English, French and several other languages

Data collection method

Self-report questionnaire, by proxy or by interview, in hard copy, in person or by telephone.

Target population

Adults

Interpretation of the results and thresholds

A five-point scale measures 12 items. There are two methods to calculate the scores. The shortest, simplest method consists in adding up the scores attributed to each item. The total score of this method ranges from 12 to 60. The second method, which is more complex, is an item-response-theory, which allows for the weighting of the items. The algorithm is available on the WHO website. In the article by Sjonnesen et al. (2016), which uses the CCHS 2012 data, it is the simple method that has been preferred. The population-based standards are also available on the WHO website.

Is the questionnaire available in the toolkit?

Yes, see Questionnaire 14.

Other versions

The long version comprises 36 items and the short version, 12 items. Three additional questions measure the extent of the burden of dysfunction.

Name of the instrument

Social functioning questionnaire

Abbreviation

SFQ

16

French, English and Spanish

Data collection method

Self-report questionnaire, in hard copy, in person or by telephone.

Target population

Adults

Interpretation of the results and thresholds

The 16 items of this instrument are ranked on a five-level scale. The eight frequency items (indicator F) are ranked from 1 to 5 (score range 8-40). The eight satisfaction items (indicator S) are ranked from 1 to 5 (score range 8-40). The maximum total score is 25. While doing so is hardly recommended, it is possible to create a global indicator G that represents the sum of the indicators F and S (score range 16-80). The higher the score, the better the social functioning.
