ABSTRACT
The study was designed to examine the relationships between sleep disturbance, negative affect and quality of life among patients with maintenance hemodialysis. A total of 118 patients in Shanghai, China, with maintenance hemodialysis (>40 years old) participated in the study. They completed three questionnaires: the Positive and Negative Affect Scale (PANAS), the Pittsburgh Sleep Quality Index (PSQI) and the European Quality of 5-Dimensions (EQ-5D-5L). Results showed that male participants’ negative affect scored significantly higher than female participants’.The mean global PSQI score was 8.64 (poor sleepers score 6 or more); sleep disturbance affected 63.6% of the patients, which indicated that in general the participants’ sleep quality was relatively poor.The patients with worse sleep quality and negative affect were more likely to have a lower quality of life. In addition, the effect of the sleep disturbance on quality of life was mediated by negative affect (The Z value of Sobel test was -3.18, p< .01).These findings suggest sleep disturbance and negative affect were common among patients with maintenance hemodialysis and had a negative impact on their quality of life; negative affect may mediate the relationship between sleep disturbance and quality of life.
