目的 了解肺癌化疗患者健康坚韧性现况及其影响因素。方法 采用便利抽样法，选取2020年7月—2021年8月广州市某三级甲等医院收治的286例肺癌化疗患者作为研究对象，采用一般资料调查表、健康坚韧性量表、一般自我效能感量表和社会支持评定量表进行调查。结果 肺癌化疗患者健康坚韧性得分（114.51±18.23）分。多元线性回归分析结果显示：性别、家庭人均月收入、病理分期、自我效能感、社会支持总分是健康坚韧性得分的主要影响因素，可解释总变异的43.8%。结论 肺癌化疗患者健康坚韧性处于中等偏低水平，医护人员需重点关注男性、家庭人均月收入低、病理分期高的患者，增强患者的自我效能感，调动患者的社会支持系统，以提高患者的健康坚韧性，从而促进患者身心康复。

Objective To investigate the status and influencing factors of health-related hardiness in lung cancer patients undergoing chemotherapy. Methods A total of 286 lung cancer patients undergoing chemotherapy admitted in a grade Ⅲ，class A hospital in Guangzhou from July 2020 to August 2021 were selected using convenience sampling method. The general information questionnaire，Health-related Hardiness Scale，General Self-Efficacy Scale，Social Support Rating Scale were employed for assessment. Results The health-related hardiness scores of lung cancer patients undergoing chemotherapy were（114.51±18.23） points. The results of multiple linear regression analysis showed that gender，family per capita monthly income，pathological stage，self-efficacy，and total social support scores were the main influencing factors of health-related hardiness scores，which explained 43.8% of the total variance. Conclusion The health-related hardiness of lung cancer patients undergoing chemotherapy is at a moderately low level. Medical staff should pay more attention to male patients，patients with lower family per capita monthly income and worse pathological stages. Meanwhile，they need to enhance patients’ self-efficacy and mobilize patients’ social support system，so as to improve patients’ health-related hardiness and promote the physical and mental recovery of the patients.
