Effects of perceived stress, self-acceptance and social support on insomnia in hemodialysis patients: A cross-sectional study.

Objective: The aim of this study was to explore the influence of perceived stress, self-acceptance and social support on insomnia among hemodialysis patients in China.

Methods: A cross-sectional study was conducted in Gansu, China, from May 2022 to July 2022. The Chinese Perceived Stress Scales (CPSS), Athens Insomnia Scale (AIS), Self-acceptance Questionnaire (SAQ), and Perceived Social Support Scale (PSSS) were evaluated in 610 hemodialysis patients.

Results: The prevalence of insomnia among hemodialysis patients was 40.7% in this study. Insomnia was positively correlated with perceived stress (r = 0.742, P < 0.01), and negatively correlated with self-acceptance (r = -0.531, P < 0.01) and social support (r = -0.574, P < 0.01). Self-acceptance played a mediating role in perceived stress and insomnia, with the mediating effect accounting for 13.8% of the total effect. Social support played a moderating role in perceived stress and insomnia (β = -0.008, t = -5.112, P < 0.001).

Conclusions: The results of this study enrich the research on the influencing factors of insomnia in hemodialysis patients and provide theoretical basis and practical guidance for improving the sleep quality of hemodialysis patients.
