Summary WHODAS 2.0 Theory

WHODAS 2.0 (Information combined with Social Interaction lecture information)
What is the WHODAS 2.0?
→ WORLD HEALTH ORGANIZATION DISABILITY ASSESSMENT SCHEDULE
 A generic assessment instrument for health and disability
 Tool to produce standardized disability levels and profiles
o That are reliable
o Applicable across cultures, in all adult populations
 Used across all diseases, including mental, neurological, and addictive disorders
 Applicable in both clinical and general population settings
 Short, simple, and easy to administer (5 to 20 minutes)
 Directly linked at conceptual level to the International Classification of Functioning,
Disability and Health (ICF)

 What levels of functioning in the 6 domains of life captured by the WHODAS 2.0?
o Cognition – understanding & communicating
o Mobility – moving & getting around
o Self-care – hygiene, dressing, eating & staying alone
o Getting along (Social Interaction) – interacting with other people
o Life activities – domestic responsibilities, leisure, work & school
o Participation – joining in community activities

 How does WHODAS 2.0 differ from the original WHODAS?
o Original WHODAS published in 1988
o WHODAS 2.0 supersedes WHODAS II
 altogether different instrument
 grounded in the conceptual framework of the ICF
o Integrates individual's level of functioning in major life domains and directly
corresponds with ICF's "activity and participation" dimensions
o WHODAS 2.0 was developed through a collaborative international approach
with the aim of developing a single generic instrument for assessing health
status and disability across different cultures and settings

 What are the different versions of the WHODAS 2.0?
o Describe the 36-item version
 Provides most detail
 Allows to compute overall and 6 domain specific functioning scores
 Available as interviewer-, self-, and proxy-administered forms
 Average interview time: 20 min.
 *NOTE changes in scoring
 No longer using a 5 point scale from 1-5 for difficulty
 Now use a 5 point scale from 0-4
o 0 = none
o 1 = mild
o 2 = moderate
o 3 = severe
o 4 = extreme / cannot do

, o Describe the 12-item version
 Useful for brief assessments of overall functioning in surveys
 Allows to compute overall functioning scores
 Explains 81% of the variance of the 36-item version
 Available as interviewer-, self-, and proxy-administered forms
 Average interview time: 5 min
 4 sections + 2 flashcards
 Face sheet
 Demographic and background information
 Preamble
 Core questions
→ in last 30 days how much difficulty did you have in:
o Standing for long periods such as 30 minutes?
o Taking care of your household responsibilities?
o Learning a new task, for example, learning how to get
to a new place?
o How much of a problem did you have joining in
community activities (festivities, religious etc.) in the
same way as anyone else can?
o How much have you been emotionally affected by your
health problems?
o Concentrating on doing something for ten minutes?
o Walking a long distance such as a kilometer [or
equivalent]?
o Washing your whole body?
o Getting dressed?
o Dealing with people you do not know?
o Maintaining a friendship?
o Your day-to-day work?

 Describe the 12+24-item version
 Uses 12 items to screen for problematic domains of functioning
 Based on positive responses to initial 12 items, respondents may be
given up to 24 additional questions
 Only administered by interview / computer-adaptive testing (CAT)
 Average interview time 20 mins

 How is the WHODAS 2.0 administered?
o Self-administration via Paper-and-pencil version of WHODAS 2.0
o WHODAS 2.0 can be administered as an interview in person or over the
telephone.
o Sometimes it may be desirable to obtain a proxy / third-party view of
functioning such as; family members, caretakers, or other observers
