The purpose of the study is to explore and describe the lived experience of family members with gastric cancer patients using the grounded theory methodology. The participants were ten spouses of gastric cancer patients who had some kind of treatment at the hospital. They were asked open-ended and descriptive questions in order for them to talk about their experiences in their owl terms. As the interview progressed the questions became more specific to discuss themes and working hypotheses that emerged from the analysis of previous interviews. All interviews were tape-recorded and transcribed for the analysis. Constant the core category that was emerged from the comparative analysis is "magmaggam" which can be described as a psychological distress due to a high level of uncertainty regarding the health of the patient and the future of the caregivers. Psychological distress includes several emotional feelings such as frustration, anxiety, fear, guilty, and self depreciation. Subcategories or strategies related to the core category are 1) managing illness, 2) using folk medicine, 3) giving the patient a reason to live, 4) being patient, 5) losing reality, 6) anticipatory experience on the patient's death and parting, and 7) changing interpersonal relationships. The results of this study would help clinical nurses to develop nursing intervention to help spouses of gastric cancer patients establish efficient coping strategies in dealing with the problems they face.
