Abstract: Objective: To explore the mediating role of self-management efficacy between fear of progression(FoP), anxiety, and depression among postoperative patients with lung cancer. Methods: With convenience sampling, primary lung cancer patients in a tertiary grade A hospital in Tianjin were selected as the research subjects. The survey was conducted by general information questionnaire, Strategies Used by People to Promote Health (SUPPH), Fear of Progression Questionnaire Short Form (FoP-Q-SF) and Hospital Anxiety and Depression Scale(HADS). Moreover, the mediation model was developed and validated. Results: 320 questionnaires were distributed and 298 questionnaires were collected, with an effective recovery rate of 93.13%. The scores of self-management efficacy, FoP, anxiety and depression among postoperative patients with lung cancer were (97.26 ± 24.36), (28.95 ± 8.75), 6.00(3.00, 8.00) and 4.50(2.00, 7.00), respectively. The patient's anxiety and depression were significantly negatively correlated with self-management efficacy (P<0.001), and were significantly positively correlated with FoP(P<0.001). Self-management efficacy was significantly negatively correlated with FoP (P<0.001). The self-management efficacy of patients after lung cencer surgery had a partial mediation role between FoP and anxiety and depression in postoperative patients with lung cancer. The mediating effect values were 0.024 and 0.033 respectively, accounting for 10.17% and 15.07% of the total effect. Conclusion: Medical staff should pay attention to the psychological state of postoperative patients with lung cancer, and the effective intervention should be carried out to improve their self-management efficacy and reduce the level of FoP, so as to improve patients' negative emotions.
