Abstract

Objective To investigate the effect of motivational interviewing on literacy and quality of life of patients on maintenance hemodialysis. Methods Using convenience sampling method, 100 patients on maintenance hemodialysis were selected from March 2016 to March 2018 in a blood purification center of a Class Ⅲ Grade A hospital. According to dialysis time, the patients were divided into the intervention group (n=50) and control group (n=50) . Motivational interviews were conducted in the intervention group. Traditional education methods were used in the control group. The two groups' scores in literacy and quality of life from Health Literacy of Patients with Chronic Diseases Questionnaire and Kidney Disease Questionnaire (KDQ) before and after intervention were compared. Results After 6 months of intervention, the total score of literacy in the intervention group increased from (87.34±2.85) to (97.34±3.02) . The scores of three dimensions of information acquisition ability , communication and interaction ability and willingness to improve health were higher than those before intervention, and the total score of literacy and above three dimensions in the intervention group were higher than those in the control group with statistical differences (P<0.05) . The total score of quality of life in the intervention group increased from (100.64±17.62) to (115.60±16.15) , among which the scores of somatic symptoms , fatigue and relationship with others in the intervention group were higher than those before intervention, and the total score of quality of life and the above three dimensions in the intervention group were higher than those in the control group, the differences were statistically significant (P<0.05) . Conclusions Motivational interviews can improve the literacy level of maintenance hemodialysis patients, enhance their awareness of improving health, change their bad behaviors, and improve their quality of life.
