The proxy version of the WHO Disability Assessment Schedule (WHODAS) collects information about an individual’s disability and functioning from a knowledgeable informant, such as a family member or caregiver. This version is used when the individual cannot complete the assessment due to cognitive or communication impairments. It includes structured questions assessing abilities in domains like cognition, mobility, self-care, relationships, daily activities, and community participation. This method aids healthcare professionals and researchers in understanding the impact of disabilities and guiding appropriate interventions and support services.
