Abstract

BACKGROUND: Lung cancer is one of the most common malignant tumours that threaten human health globally. Radical resection under thoracoscopic guidance has been accepted as the major therapeutic option for treating lung cancer clinically. However, the procedure still has some adverse impacts on the comfort of patients following thoracoscopic surgery. OBJECTIVE: To analyse the reliability and validity of the postoperative comfort scale for patients with lung cancer undergoing endoscopic surgery and to evaluate patient comfort. METHODS: With 210 patients with lung cancer undergoing endoscopic surgery as the participants, this study was performed to assess the reliability and validity of the postoperative comfort scale for patients with lung cancer undergoing endoscopic surgery, with the assessment performed by eight experts. RESULTS: The postoperative comfort scale included 28 items and consisted of four dimensions (physiological, psychological, socio-cultural and environmental). The total Cronbach’s alpha coefficient of the scale was 0.851, and the split-half reliability coefficient was 0.875. Meanwhile, the content validity index (CVI) was 0.875∼1, and the scale-level average CVI was 0.99. The Chi-square/degree-of-freedom ratio of construct validity was 2.844, suggesting a good model-fitting. Furthermore, the overall average score of patient comfort was 3.72 ± 0.57, with scores ranging between 3.59 ± 0.71 and 3.83 ± 1.06 across all four dimensions, with the lowest score in the physiological dimension. CONCLUSION: The postoperative comfort scale has good reliability and validity and can be applied for the postoperative comfort assessment of patients undergoing endoscopic surgery for lung cancer. Overall, the degree of patient comfort in this assessment was moderate, meaning targeted measures may be required to further improve patient comfort, especially in the physiological dimension.
