Interactions of Spiritual Well-Being, Symptoms, and Quality of Life in Patients Undergoing Treatment for Non-Small Cell Lung Cancer: A Cross-Sectional Study.

OBJECTIVES

To investigate the relationship of spiritual well-being and quality of life (QOL) in patients undergoing treatment for non-small cell lung cancer (NSCLC) and to identify the role of four different symptoms (ie, appetite loss, dyspnea, pain, and fatigue) in mediating this relationship DATA SOURCES: A total of 132 consecutive patients undergoing chemotherapy, radiotherapy, or concurrent chemoradiotherapy for NSCLC from National University Hospital were examined. Symptoms were assessed using the symptom subscale of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-C30 (QLQ-C30). Spiritual well-being was assessed using the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being scale. Global QOL was assessed using the item on global health status from the European Organization for Research and Treatment of Cancer. Data of all self-reported surveys were analyzed using serial multiple mediation analysis.

CONCLUSION

Spiritual well-being directly affected QOL in patients undergoing treatment for NSCLC. In addition, a serial multiple mediation model showed causal relationships of spiritual well-being on appetite loss, appetite loss on dyspnea, dyspnea on pain, pain on fatigue, and fatigue on QOL.

IMPLICATIONS FOR NURSING PRACTICE

Providing integrated care that considers spiritual well-being may improve the QOL of patients undergoing treatment for NSCLC. Our findings emphasized the need to conduct routine assessments of spiritual well-being and symptoms when characterizing patient QOL.
