Health assets, a term that refers to patients' strengths and potentials, has emerged as an important aspect of health care. A conceptual analysis of health assets revealed five core dimensions: mobilization, motivational, relational, volitional, and protective strengths. How nurses experience and use patients' health assets, however, is unknown. In this qualitative study, 26 expert nurses in cancer care participated in focus group interviews. The nurses had a large repertoire of experiences with cancer patients' health assets. When the data were subjected to thematic analysis, three new core dimensions were revealed: cognitive, emotional, and physical strengths. Balancing processes within and among health assets--identified as an overriding theme--appeared to be affected by individual and contextual variations. The nurses realized that patients' health assets could be better used and voiced a need for the clinical and organizational support to do so. New issues about health assets raised in this study may be caused by its novel context (e.g., expert nurses in oncology care). More research is needed on health assets in other contexts, such as patients with different health problems, and of possible strategies to support nurses' use of health assets.
