Third-party disability in ongoing vestibular disorders through the lens of the ICF framework.

To identify presence and nature of Third-Party Disability experienced by Significant Others (SOs) of people with ongoing vestibular symptoms using the World Health Organisation International Classification of Functioning, Disability and Health (WHO-ICF) framework. Qualitative semi-structured interviews were conducted and analysed by mapping transcripts to the WHO-ICF framework. Ten SOs of people with ongoing vestibular symptoms were interviewed. Maximum variation sampling was used. Data mapped to 5 codes in the body functions component of the ICF, highlighting psychological impact on the SO and a broad range of negative emotions; 28 codes in the activities and participations component, showing impaired ability across several areas of the SO's life including social life, communication, general tasks and maintaining domestic balance; and 19 codes in the environmental factors component, highlighting the importance of supportive relationships and functioning health systems. Third-Party Disability was identified, including psychological impacts on the SO, interruption to their daily lives and increased domestic responsibility. Health professionals may lessen disability by encouraging support networks and practicing family-centred care.
