Objective: To investigate the effect of Teach-back health education combined with graded exposure therapy on postoperative kinesiophobia, psychological resilience, and post-traumatic growth in patients with lung cancer. Methods: A total of 102 patients who underwent lung cancer surgery were selected and divided into an intervention group (n=51) and a control group (n=51) according to the different intervention methods. The control group received routine care, while the intervention group received additional Teach-back health education and graded exposure therapy. The intervention lasted for 4 weeks, after 4 weeks the levels of kinesiophobia (Tampa Scale of Kinesiophobia, TSK), psychological resilience (Connor-Davidson Resilience Scale, CD-RISC), and post-traumatic growth (Chinese-Posttraumatic Growth Inventory, C-PTGI) were evaluated in both groups. Results: After the intervention, the intervention group showed lower scores in all dimensions of the TSK—including kinesiophobia, functional disorder, activity avoidance, and risk perception—as well as in the total score compared to the control group (P<0.05). The intervention group demonstrated higher scores in all dimensions of the CD-RISC—including strength, tenacity, and optimism—compared to the control group (P<0.05). The intervention group exhibited higher scores in all dimensions of the C-PTGI—such as relationship with others, personal strength, spiritual change, appreciation of life, and new possibilities—as well as in the total score compared to the control group (P<0.05). Conclusion: The combined intervention of Teach-back health education and graded exposure therapy has positive clinical value in reducing postoperative kinesiophobia, enhancing psychological resilience, and promoting post-traumatic growth in patients with lung cancer.
