Abstract:
Objective:To investigate the status and the relationship of social support, depression, personality and sleep quality in patients with malignant bone tumors and their relationship, and provide scientific basis for postoperative rehabilitation and nursing.Methods:186 patients with malignant bone tumors undergoing chemotherapy in orthopedics department of the Second Xiangya Hospital of Central South University from January 2017 to December 2019 were selected to complete the Center for Epidemiological Studies Depression Scale (CES-D), the Perceived Social Support Scale (PSSS), the Optimism-Pessimism Scale (OPS), and the Pittsburgh Sleep Quality Index (PSQI). The demographic differences of various variables were compared and the correlation among social support, personality, sleep quality and depression in patients with malignant bone tumors were tested. Then, by structural equation model, the mediating role of personality and sleep quality between social support and depression was analyzed.Results:The incidence of depression in patients with malignant bone tumors was 57.6%(107/186), and the incidence of severe depression was 14.7%(27/186). Depression in patients with malignant bone tumors was negatively correlated with scores of social support and pessimism (all P<0.01), and positively correlated with scores of optimism and sleep quality (all P<0.05); Family support, pessimism, sleep quality and daytime dysfunction can effectively predict depression in patients with malignant bone tumors (all P≤0.05); Structural equation model analysis showed that personality and sleep quality play a chain mediating role between social support and depression. Conclusions:The incidence of depression is higher in patients with malignant bone tumors. Family support, pessimism, sleep quality and daytime dysfunction are predictors of depression in patients with malignant bone tumors. Personality and sleep quality play a chain mediating role in the influence of social support on depression.
