Abstract :Aim: This study was conducted to investigate the effects of depression and anxiety on sleep quality in patients receiving hemodialysis treatment and to evaluate these relationships. Methods: The study was conducted in a cross-sectional design in a training and research hospital in Turkey. The study included 101 hemodialysis patients and 100 healthy control participants. The sample size was calculated using G*Power software (effect size = 0.48; α = 0.05; power = 0.95); requiring a minimum of 180 participants. Hospital Anxiety and Depression Scale (HADS); Pittsburgh Sleep Quality Index (PSQI); Insomnia Severity Index (ISI); and Epworth Sleepiness Scale (ESS) were used as data collection tools. Independent samples t-tests and Pearson correlations were used for group comparisons and associations. Multiple linear regression was employed to identify predictors of sleep quality. Results: Depression and anxiety scores were significantly higher in the hemodialysis group compared to the control group (p<0.001). Poor sleep quality was detected in 79.2% of hemodialysis patients; and PSQI scores were significantly higher compared to the control group (p<0.001). Multiple regression analysis showed that anxiety; depression; and marital status were significant predictors of PSQI scores; explaining 56.8% of the variance (adjusted R² = 0.568; p < 0.001). Conclusion: The study showed that depression and anxiety significantly negatively affected sleep quality in hemodialysis patients. These results highlight the importance of incorporating psychosocial interventions within the care of this population and emphasize the need for healthcare providers to address psychological factors when managing sleep disturbances.
