Quality of care is determined not only by political decisions but also by how those policies are understood and managed by professionals when put into action. Home care services, the most common form of elder care in Sweden today, should include social support, which is very important for health and wellbeing. And yet, support for social participation seems to be lacking. Understanding prevalent social constructs and their possible impacts on focus and content of social practice in home care could reveal ways to address social support in home care. Therefore, this article highlights how professionals in home care provision talk about older home care recipients' loneliness and social needs, and how these repertoires are related to professionals' opportunities and obligations to support those social needs. The study included 22 persons from different professions in home care provision, from two municipalities in northern Sweden. Nine individual interviews and four group interviews were conducted, recorded, transcribed, and analyzed using a discourse psychology approach. The results show two interpretative repertoires in which notions of otherness and likeness guided definitions and support regarding loneliness, social needs, and social support. This study reveals assumptions that underpin and structure the practices of home care. As the interpretative repertoires provided differing and partly opposing views on how to provide social support and combat loneliness, it seems important to also address the broader issues of professional identities and how loneliness is defined and approached.
