Abstract:
Objective:To investigate the current status of fear of falling in postoperative cardiac surgery patients, and to analyze its influencing factors and interrelationships.Methods:A convenience sample of 246 postoperative cardiac surgery patients hospitalized in the Department of Cardiac Surgery, the First Affiliated Hospital of Xiamen University, from December 2023 to December 2024 was surveyed. The Body Image Scale, the Personal Mastery Scale, the Fear of Falling Questionnaire-Revised, and a self-designed demographic and clinical questionnaire were used for data collection. Pearson correlation analysis was conducted to examine the relationships among body image, personal mastery, and fear of falling. PROCESS Model 4 was applied to test the mediating role of personal mastery between body image and fear of falling, with bootstrapping for verification.Results:A total of 246 questionnaires were distributed, and 236 valid responses were obtained (valid response rate: 95.93%) . The body image score was (14.02±6.36) , personal mastery score was (20.44±4.16) , and fear of falling score was (38.28±10.83) . Body image was positively correlated with fear of falling ( r=0.324, P<0.01) , while personal mastery was negatively correlated with fear of falling ( r=-0.552, P<0.01) . After controlling for variables with statistically significant differences in univariate analysis (including sex, age, education level, body mass index, history of syncope, pain level, and self-rated preoperative exercise capacity) , PROCESS analysis showed that body image had a direct positive effect on fear of falling ( β=0.288, P<0.05) , and also indirectly affected fear of falling through personal mastery, with the indirect effect accounting for 49.5% of the total effect (0.237/0.525) . Conclusions:Postoperative cardiac surgery patients require improvement in body image, personal mastery, and fear of falling. Understanding how body image influences fear of falling through personal mastery not only enriches theoretical frameworks but also provides guidance for psychological interventions in clinical practice, thereby meeting patients' psychological support needs during rehabilitation.
