Objective To explore the impacts of illness perception and coping style on social participation in patients receiving surgery for Stanford type A aortic dissection， so as to provide reference for making intervention measures. Methods A total of 214 patients with Stanford type A aortic dissection who had received surgical treatment were selected by convenience sampling. Brief Illness Perception Questionnaire（BIPQ），Medical Coping Modes Questionnaire（MCMQ）， and Impact on Participation and Autonomy questionnaire（IPA） were used for survey. Bootstrapping was used to analyze the association of social participation with illness perception and coping style. Results For the patients， IPA score was （51.74 ± 16.50） points， BIPQ score was （49.74 ± 12.61）， and the subscales scores of correspondence to confrontation， avoidance， and acceptance-resignation were （22.87 ± 5.18）， （14.96 ± 3.05） and （10.80 ± 3.93）， respectively. Illness perception was positively correlated with social participation（P < 0.01）， confrontation was negatively correlated with illness perception and social participation（P < 0.01）， surrender was positively correlated with illness perception and social participation（P < 0.01）. confrontation and acceptance-resignation play a parallel mediating role between illness perception and social participation（P < 0.01）， accounting for 29.65% and 16.05% of the total effect， respectively. Conclusions Social participation is at a medium and below level in the patients receiving surgery for Stanford type A aortic dissection， coping style is intermediary variable for illness perception and social participation. By increasing the positive illness perception in the patients， medical staff can instruct them to cope actively with their disease and to enhance their social participation.
