Përmbledhja	The Washington Group Short Set on Functioning is a brief, standardized set of six survey questions designed to identify people at risk of participation restrictions because of difficulty in basic functional domains. Developed by the Washington Group on Disability Statistics under United Nations auspices, the short set asks about difficulty in seeing, hearing, walking or climbing steps, remembering or concentrating, self-care, and communicating, each answered on a common four-level scale running from no difficulty to cannot do at all. Its purpose, as set out by Madans and colleagues in 2011, is to produce internationally comparable disability statistics that can be collected even in a population census and that support monitoring of the UN Convention on the Rights of Persons with Disabilities. The questions are grounded in the functioning perspective of the WHO ICF, deliberately measuring difficulty in carrying out basic actions rather than diagnoses or impairments. A simple cut-off on the difficulty scale converts the answers into a disability classification used to estimate prevalence and to disaggregate other indicators.	The Model Disability Survey is a general-population survey developed jointly by the World Health Organization and the World Bank to generate comprehensive, internationally comparable data on functioning and disability. Unlike instruments that classify people as disabled or not, it operationalizes the biopsychosocial model of the WHO ICF, treating disability as the outcome of an interaction between a person's intrinsic capacity and the environment in which they live. The survey collects detailed self-reported information on how much difficulty people have across many domains of functioning, distinguishing what a person can do in a standardized environment (capacity) from what they actually do in their own environment (performance), and it separately measures environmental barriers and facilitators. As documented by Sabariego and colleagues in 2022, these responses are combined using a Rasch measurement model into a single metric scale, so that disability is represented as a continuum running across the whole population rather than as a yes/no category. The result is a graded picture of functioning suited to prevalence estimation, equity analysis, and policy on a comparable metric.
