BackgroundDemoralization is a psychological response that is frequently observed in patients with cancer or advanced diseases. Depression and demoralization syndrome in patients with cancer are closely related to suicidal behavior.ObjectiveThe purpose of this study was to explore the factors affecting demoralization of patients with cancer from a depression perspective, to assist with distinguishing patient emotions and provide appropriate intervention as early as possible, thereby enabling patients to receive proper care.MethodsA systematic review and meta-analysis was employed in this study. The databases included Cumulative Index for Nursing and Allied Health Literature, Cochrane, PubMed/ MEDLINE, PsycINFO, and Centre for European Policy Studies, and reference lists of articles. Experts in this field also were contacted. Based on inclusion criteria, 2 investigators selected the research and reviewed each study's quality according to the Newcastle-Ottawa Scale. Five correlational studies with 32 subjects were identified.ResultsThe countries of studies included Australia, Germany, Taiwan, and the United States. There was a statistically significant difference in depression between patients with cancer in the high-demoralization group and those of the low-demoralization group (odds ratio = 9.65, 95% CI: 6.99-13.33, Z = 15.002, p < 0.0001). Four studies regarded demoralization and depression as distinguishable.ConclusionsThe demoralization of patients with cancer was highly correlated with depression. Therefore, the suicide risk of demoralized patients without depression must also be assessed to prevent patients with high suicide risk from being neglected. If medical staff can perceive patient's demoralization issues earlier, they can more effectively prevent patients' depression from occurring, which benefits suicide prevention.Copyright © 2015 The Academy of Psychosomatic Medicine.
