Background: Both demoralization and depression are common forms of psychological distress in cancer patients. This study aimed to investigate the severity of demoralization in Chinese cancer patients and to explore the factors influencing depression and demoralization and their effects on quality of life to better understand the differences and the relationship between demoralization and depression.
Methods: Cross-sectional study design, in-patients sequentially recruited from a tertiary-level cancer hospital in Beijing between January 2016 and April 2016 completed Mandarin version of Demoralization Scale (DS-MV), Patient Health Questionnaire-9 (PHQ-9), Revised Life Orientation Test (CLOT-R), Beck Hopelessness Scale (BHS), and the 12-items Short Form Health Survey, version 2 (SF-12 V2) and provided socio-demographic and clinical information.
Results: 296/424 (70.0%) of patients completed questionnaires. The mean score of DS is 30.4 (SD = 13.0). There are 28% (83/296) patients who experienced a low level of depression but a high level of demoralization. Resignation medical coping method (b = 0.279, P < .001), hopelessness (b = 0.492, P < .001), positive life orientation (b = -0.170, P < .001), and education level (b = -0.132, P < .001) were found to be predictors of demoralization, while only resignation medical coping method (b = 0.373, P < .001) and hopelessness (b = 0.350, P < .001) were found to be predictors of depression. Depression is a mediator between demoralization and physical aspects of quality of life (γ = -0.1604, LLCI = -0.244, ULCI = -0.080).
Conclusion: Demoralization is a prevalent psychiatric problem in Chinese cancer patients, and a large proportion of patients had low depression but high demoralization. Therefore, screening for demoralization in Chinese oncology practice is essential. A positive life orientation was found to be protective against demoralization.
