Pain affects people’s quality of life, and is an important issue for social justice in equal health. This paper will present the preliminary analysis on professionals working closely with people with disabilities who, due to their disabilities, have difficulties communicating pain. Such disabilities may include intellectual disabilities, disabilities on the autism spectrum, and severe and persistent intellectual disability following brain injury in adulthood or mental disability not due to normal ageing. Previous studies on pain among groups unable to self-report have mainly focused on the role of the nurse (see for example Hemsley, Balandin & Worrall, 2012; Martin, Connor-Fenelon & Lyons, 2012). Few studies have focused on housing, and knowledge of the Swedish welfare context is lacking. By conducting interviews with professionals working in LSS-housing for people with, for example, intellectual disabilities and disabilities within the autism spectrum, this study explores how the professionals’ work to detect and interpret pain in the residents who have difficulty communicating pain. Through a critical disability perspective we analyses and identifies what barriers and what resources exists, what models that are currently used and what strategies the professionals have, as well as discusses how these insights can engender social justice in health.
