It is essential to examine conflict between patients and health care professionals from the patient's perspective. The purposes of this study were to 1) identify sources of conflict, 2) determine nursing interventions that alleviate conflict, and 3) test a conceptual framework of sources of conflict. This phenomenological study focused on children with cancer and their parents' perceptions of conflicts with health care professionals as well as what they thought helped with such conflicts. Their reports of conflict were compared to C. W. Moore's circle of conflict conceptual framework. A purposive sample of 27 participants (9 children, 14 mothers, and 4 fathers) participated in the study. Study findings showed that conflict occurred between health care professionals and families originating from differences in expectations and desires regarding data, interests, structure, relationships, and values, consistent with C. W. Moore's conceptual framework. Nursing interventions reported by children and parents to be helpful in preventing or alleviating conflict were identified. C. W. Moore's framework may provide a valuable structure for assessing conflict and designing nursing interventions to alleviate conflict.
