Only one empirical study, the one by Zingmark, Norberg and Sandman published in 1995, explicitly focuses on at-homeness, the feeling of being metaphorically at-home, as a particular aspect of wellness. However, other studies reveal aspects of at-homeness, but if or how such aspects of at-homeness are related to each other is unclear. For this reason, the aim was to review Scandinavian nursing research related to at-homeness in the context of wellness-illness in severe and long-term conditions in order to take a step towards conceptual clarification of "at-homeness.'' The review included interpretive studies related to severe and long-term illness conducted in Sweden: 10 original articles and 5 doctoral theses. "At-homeness'' was found to be a contextually related meaning of wellness despite illness and disease embedded in the continuum of being metaphorically at-home and metaphorically homeless. This was characterized by three interrelated aspects and four processes: being safe through expanding-limiting experiences of illness and time, being connected through reunifying-detaching ways of relating, and being centred through recognition-non-recognition of oneself in the experience and others giving-withdrawing a place for oneself. This conceptualization is to be regarded as a step in conceptual clarification. Further empirical investigation and theoretical development of "at-homeness'' are needed. The conceptualization will be a step of plausible significance for the evaluation of interventions aimed at enhancing wellness for people with severe long-term illness, such as the frail elderly, and people with chronic illness or palliative care needs.
