Study on psychological resilience and associated influencing factors in lung cancer patients with bone metastases

Background: Evaluating the psychological resilience of lung cancer (LC) patients helps understand their mental state and guides future treatment. However, there is limited research on the psychological resilience of LC patients with bone metastases.

Aim: To explore the psychological resilience of LC patients with bone metastases and identify factors that may influence psychological resilience.

Methods: LC patients with bone metastases who met the inclusion criteria were screened from those admitted to the Third Affiliated Hospital of Wenzhou Medical University. The psychological scores of the enrolled patients were collected. They were then grouped based on the mean psychological score: Those with scores lower than the mean value were placed in the low-score group and those with scores equal to or greater than the mean value was placed in the high-score group. The baseline data (age, gender, education level, marital status, residence, monthly income, and religious beliefs), along with self-efficacy and medical coping mode scores, were compared.

Results: This study included 142 LC patients with bone metastases admitted to our hospital from June 2022 to December 2023, with an average psychological resilience score of 63.24 ± 9.96 points. After grouping, the low-score group consisted of 69 patients, including 42 males and 27 females, with an average age of 67.38 ± 9.55 years. The high-score group consisted of 73 patients, including 49 males and 24 females, with a mean age of 61.97 ± 5.00 years. χ ² analysis revealed significant differences between the two groups in education level (χ ² = 6.604, P = 0.037), residence (χ ² = 12.950, P = 0.002), monthly income (χ ² = 9.375, P = 0.009), and medical coping modes (χ ² = 19.150, P = 0.000). Independent sample t-test showed that the high-score group had significantly higher self-efficacy scores (t = 3.383, P = 0.001) and lower age than the low-score group (t = 4.256, P < 0.001). Furthermore, multivariate logistic regression hazard analysis confirmed that self-efficacy is an independent protective factor for psychological resilience [odds ratio (OR) = 0.926, P = 0.035, 95% confidence interval (CI): 0.862-0.995], while age (OR = 1.099, P = 0.003, 95%CI: 1.034-1.169) and medical coping modes (avoidance vs confrontation: OR = 3.767, P = 0.012, 95%CI: 1.342-10.570; resignation vs confrontation: OR = 5.687, P = 0.001, 95%CI: 1.974-16.385) were identified as independent risk factors. A predictive model based on self-efficacy, age, and medical coping modes was developed. The receiver operating characteristic analysis showed an area under the curve value of 0.778 (95%CI: 0.701-0.856, P < 0.001), indicating that the model has good predictive performance.

Conclusion: LC patients with bone metastases are less psychologically resilient than the general population. Factors such as self-efficacy, age, and medical coping modes influence their psychological resilience. Patients with low self-efficacy, old age, and avoidance/resignation coping modes should be closely observed.
