目的 探讨信息需求和患者信任在肺癌患者疾病感知与术前焦虑之间的多重中介作用。方法 采用便利抽样法选取上海市某三级甲等医院收治的308例肺癌患者为研究对象，采用一般资料调查表、阿姆斯特丹术前焦虑与信息量表、简化版疾病感知问卷及维克森林医师信任量表对其进行调查。结果 肺癌患者术前焦虑与疾病感知、信息需求呈正相关（r=0.470,r=0＜646,P＜0.001），术前焦虑与患者信任呈负相关（r=-0.400,P＜0.001），信息需求和患者信任在疾病感知与术前焦虑之间起多重中介作用。结论 肺癌患者的疾病感知不仅直接影响术前焦虑，还可通过信息需求和患者信任的多重中介间接影响术前焦虑。

Objective To explore the multiple mediating effects of information needs and patient trust between illness perception and preoperative anxiety in lung cancer patients.Methods Convenience sampling method was used to select 308 lung cancer patients from a tertiary A hospital in Shanghai.The general information questionnaire,Amsterdam Anxiety and Information Scale,Brief Illness Perception Questionnaire,and Wake Forest Physician Trust Scale were used for investigation.Results Preoperative anxiety correlated positively with illness perception and information needs (r=0.470,r=0.646,P＜0.001),and negatively with patient trust (r=-0.400,P＜0.001).Information needs and patient trust played multiple mediating roles in the relationship between illness perception and preoperative anxiety.Conclusions Lung cancer patients’ illness perception not only directly affects preoperative anxiety but also indirectly predict preoperative anxiety through the multiple mediating effects of information needs and patient trust.
