Background: Spirituality is a central component of the well-being of terminally ill cancer patients.
Objective: The aim of this study was to examine the mediating or moderating role of spiritual well-being in reducing the impact of cancer-related symptoms on quality of life and the desire for hastened death in terminally ill cancer patients.
Methods: Eighty-five terminally ill cancer patients were assessed using the Taiwanese version of the M. D. Anderson Symptom Inventory, the Functional Assessment of Cancer Therapy-General, the Functional Assessment of Chronic Illness Therapy-Spiritual Well-being, the Beck Hopelessness Scale, and the Schedule of Attitudes Toward Hastened Death.
Results: Spiritual well-being was significantly negatively correlated with symptom severity (r = -0.46, P < .01). Symptom severity negatively correlated with quality of life (r = -0.54) and positively correlated with hopelessness (r = 0.51, P < .01) and the desire for hastened death (r = 0.61, P < .01). Spiritual well-being was a partial mediator and moderator between symptom severity and quality of life. Spiritual well-being was a partial mediator between symptom severity and the desire for hastened death. The meaning subscale of spiritual well-being was a more significant predictor of the desire for hastened death and quality of life than the faith subscale was.
Conclusion: Spiritual well-being may reduce the negative impacts of cancer on quality of life and the desire for hastened death.
Implications for practice: Appropriate spiritual care may reduce the negative impact of severe cancer symptoms on quality of life and the desire for hastened death in terminally ill cancer patients.
