Objective To understand the status and influencing factors of post-traumatic growth of oral cancer patients after surgery,and investigate its correlation with psychological resilience and coping styles so as to provide a basis for clinical development of positive psychological intervention program.Methods The medical records of 304 patients who underwent oral cancer surgery were collected retrospectively.The post-traumatic growth inventory(PTGI),Connor-Davidson resilience scale(CD-RISC),and the brief coping style questionnaire(SCSQ)were used for investigation.The factors influencing post-traumatic growth of oral cancer patients after surgery,and its correlation with psychological resilience and coping styles were analyzed.Results A total of 300 patients completed the survey,with a mean total score on the PTGI of(60.40±14.33)points;Therewere186(62.0%)patients with PTGI score≥57(positive group)and 114(38.00%)patients with PTGI score<57(negative group).In the negative group,the proportions of unmarried or divorced patients,those with a monthly income≤4 000 yuan,and those undergoing surgery combined with radiotherapy and chemotherapy was higher than those in the positive group.The CD-RISC scores and positive coping scores on the SCSQ were lower in the negative group,while negative coping scores were higher,with all differences being statistically significant(P<0.05).Logistic regression analysis indicated that marital status,monthly income,treatment modalities,CD-RISC score,and SCSQ score were influencing factors for post-traumatic growth of oral cancer patients(P<0.05).Spearman correlation analysis showed that total PTGI score and scores in each dimension were positively correlated with CD-RISC scores and SCSQ positive coping scores,and negatively correlated with SCSQ negative coping scores(P<0.05).Conclusions More than one-third of oral cancer patients exhibit low levels of post-traumatic growth after surgery.Special attention should be given to unmarried or divorced individuals,those with low income,patients undergoing surgery combined with radiotherapy and chemotherapy,individuals with low psychological resilience levels,and those employing negative coping strategies in order to improve prognosis.
