Analyzing the impact of Sleep Disturbances on Major depression through Serial Mediation of Stress and Rumination

Abstract

The influence of sleep disruptions on psychological disorders is profound, particularly in individuals who are diagnosed with Depressive disorder. This research delves into the intricate mechanisms by which sleep issues contribute to clinical depression by focusing on the effects of chain mediation of stress and rumination. A sample of 402 participants, recruited from mental health clinics, and data were acquired by using the Insomnia Severity Index, Perceived Stress Scale, Rumination Response Scale, and Patient Health Questionnaire. The analysis showed notable indirect pathways, illustrating that restless sleep leads to clinical depression via increased stress levels (indirect effect = 0.036, p < .05) and heightened rumination (indirect effect = 0.024, p < .01). Moreover, robust mediation effect has been found when combined both pathways of stress and rumination. Direct outcome analysis proved a strong association between sleep issues and depression (direct effect = 0.554, p < .001), this detailed relationship was constantly being noticed in both male and female cohorts. These findings highlighted the complicated dynamics between sleep quality, stress, rumination, and depression, marking the importance of dealing with these factors in therapeutic interventions. Current research intends to improve the treatment approaches that should focus on both sleep disruptions and corresponding psychological mechanisms to improve psychiatric health and well-being in individuals with Depressive Disorder.
