Objective Analysis the relationship between influencing factors and self consistency among patients under maintenance hemodialysis. Methods A total of 146 patients under maintenance hemodialysis were investigated , Research tools include: the self-designed basic information questionnaire, Self Consistency and Congruence Scale, The Meaning in Life Questionnaire,and Acceptance Action Questionnaire. One-way anova, correlation analysis,multiple regression analysis were used to analyze the relationship between influencing factors and self consistency. Results The average score of self consistency and congruence was (94.34±16.13). The score of self-stereotype dimension was (21.22±5.16), higher than that of norm of college students (t=5.132,P<0.01).While there was no difference in the other 2 dimensions of self consistency. The predictors of self consistency and congruence included Duration of dialysis, education level, sense of meaning of life, and experiential avoidance of patients,and these explained 55.40% of the total variance. Conclusions Promoting sense of meaning of life and lower experiential avoidance may help to improve self consistency and congruence for patients under maintenance hemodialysis.
