PURPOSE: This systematic review examines research and practical applications of
the World Health Organization Disability Assessment Schedule (WHODAS 2.0) as a
basis for establishing specific criteria for evaluating relevant international
scientific literature. The aims were to establish the extent of international
dissemination and use of WHODAS 2.0 and analyze psychometric research on its
various translations and adaptations. In particular, we wanted to highlight which
psychometric features have been investigated, focusing on the factor structure,
reliability, and validity of this instrument. METHOD: Following Preferred
Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) methodology, we
conducted a search for publications focused on "whodas" using the ProQuest,
PubMed, and Google Scholar electronic databases. RESULTS: We identified 810
studies from 94 countries published between 1999 and 2015. WHODAS 2.0 has been
translated into 47 languages and dialects and used in 27 areas of research (40%
in psychiatry). CONCLUSIONS: The growing number of studies indicates increasing
interest in the WHODAS 2.0 for assessing individual functioning and disability in
different settings and individual health conditions. The WHODAS 2.0 shows strong
correlations with several other measures of activity limitations; probably due to
the fact that it shares the same disability latent variable with them.
Implications for Rehabilitation WHODAS 2.0 seems to be a valid, reliable
self-report instrument for the assessment of disability. The increasing interest
in use of the WHODAS 2.0 extends to rehabilitation and life sciences rather than
being limited to psychiatry. WHODAS 2.0 is suitable for assessing health status
and disability in a variety of settings and populations. A critical issue for
rehabilitation is that a single "minimal clinically important .difference" score
for the WHODAS 2.0 has not yet been established.
