Abstract: Objective Anxiety and depression are common negative emotions in dialysis patients, which affect quality of life and mental health. The anxiety and depression, coping styles and psychological changes after "trauma (hemodialysis)" were investigated in maintenance hemodialysis patients in order to provide the evidences for clinical psychological nursing. Methods A total of 83 patients were observed. We adopted hospital anxiety and depression mood scale, simple coping style questionnaire, and posttraumatic growth scale for the investigation to these patients. SPSS 18.0 software was used for statistical analyses. Results ①Fifteen cases (18.07%) were suspected of or diagnosed as having anxiety symptoms, and 35 (42.17%) cases were suspected of or diagnosed as having depression. ②Anxiety in the patients was negatively correlated to positive coping factor (r=-0.254, P=0.021) in the simple coping style questionnaire, positively correlated to the negative coping factors (r=0.257, P=0.019), and negatively correlated to self- transformation in posttraumatic growth (r=-0.221, P=0.045), new possibilities (r=-0.227, P=0.013) and relationship with others (r=-0.247, P=0.025) in all dimensions. ③Depression in the patients was positively correlated to medical expense burden (F=5.39, P=0.006), negatively correlated to positive coping factor in simple coping style questionnaire (r=-0.368, P=0.001), positively correlated to negative coping factor (r=0.312, P=0.004), and negatively correlated to total score of posttraumatic growth (PGTI, r=-0.353, P=0.001), self-transformation (r=-0.217, P=0.049), new possibilities (r=-0.371, P=0.001), personal power (r=-0.228, P=0.038), inspiration of life (r=-0.329, P=0.002) and relationship with others (r=-0.250, P=0.023) in all dimensions. Conclusion Anxiety and depression are common symptoms in hemodialysis patients. Positive psychological counseling should be given in clinical nursing work to help the patients recover their physical and mental health.
