Objective To investigate the current status of control preference in the surgery of lung cancer patients and explore its correlation with perceived social support. MethodsGeneral information questionnaire, control preference scale, and perceived social support scale were used to investigate the lung cancer patients who underwent surgery in Beijing Cancer Hospital from February to May 2022. Results A total of 360 survey questionnaires were distributed, and 344 valid questionnaires were collected, with an effective rate of 95.6%. The expected participation style of patients was passive in 145 patients (42.2%), while the actual participation style was more inclined to be active in 154 (44.8%) patients. The compliance rate of patients’ expected and actual participation styles in the treatment control preference process was 61.9% (Kappa=0.437, P＜0.001). The results of the analysis of influencing factors showed that the level of cultural education was an influencing factor in the actual participation of lung cancer patients in surgery control preference (P=0.029). The results of Spearman's correlation analysis showed that the actual participation of lung cancer patients in surgery control preference was positively associated with perceived social support (r=0.159, P＜0.01), and its dimensions including family support (r=0.152, P＜0.01), friend support (r=0.133, P＜0.05), and other social support (r=0.142, P＜0.01). ConclusionPatients’ expected control preference style is generally consistent with their actual control preference style, which is influenced by their cultural education and positively correlated with perceived social support. Medical and nursing staff should pay attention to the participation style of patients taking surgery decisions, develop decision aids according to different education levels, and develop individualized interventions from the perspective of improving social support initially, to improve patients’ treatment compliance and treatment care satisfaction.
