Abstract: Objective To analyze the level and related psychological factors of alexithymia in clinical nurses in China. Methods The CNKI,Wanfang Database,VIP Chinese Biomedical Journal Database,Pubmed,Cochrane Library,EMBASE,APA PsycINFO,JBI evidence-based database,Proquest database,and CINAHL database were retrieved. The retrieval time was limited from the inception to March 11,2022. The relevant literature on the status of alexithymia and related psychological factors of nurses in China were searched. The studies were screened according to the pre-determined inclusion and exclusion criteria,and the extracted data were imported into Stata 16.0 for analysis. Results 19 studies were included finally,including 18 Chinese studies and 1 English study,and a total of 8 330 nurses in China were investigated. The score on the alexithymia scale of nurses in China was 54.78（95%CI：52.86-56.70）. The subgroup analysis showed the level of alexithymia of nurses in China was affected by age,children,department, education level,region,income,marital status,professional title and working hours,and has little relationship with employment form and research time. The alexithymia of nurses was positively correlated with depression,stress,and job burnout（summary r=0.67, 0.40,0.54,95%CI：0.56-0.81,0.31-0.51,0.48-0.63）,negatively correlated with social support level（summary r=-0.33,95%CI： -0.50--0.18）. Conclusion The nurses are at a high alexithymia level in China,the majority of nurses are in a critical state of alexithymia,and low seniority,having no offspring,divorce,low education level,low income and working in intensive care unit may be risk factors for nurses' alexithymia,the social support can reduce alexithymia level,while job burnout,stress and depression accentuate the level of alexithymia,so targeted intervention can be carried out according to the above factors.
