The effects of sense of coherence and rumination on sleep quality /

Abstract

Sleep quality is a problem for many adults. Poor sleep quality impacts daily function and overall health (American Academy of Sleep Medicine, 2008). The purpose of this study was to determine the effects of sense of coherence (SOC) and rumination on sleep quality. Rumination was measured as a mediating variable. Participants completed an on-line survey through snowball sampling and age ranged from 30-65 years. The majority of participants were female, 64.5% (n = 136), and most participants were Caucasian, 92.2% (n = 188). Results indicted a significant difference with rumination and gender t(209) = 3.02, p = 0.002. Structural equation modeling was used to determine the strength of the effects of SOC on sleep quality. Four path analyses were conducted: the SOC Sleep Quality Model that had a direct pathway between SOC on sleep quality, the Rumination Mediator Model that included rumination mediating SOC and sleep quality, the Complex Model that combined both the SOC Sleep Quality and Rumination Mediator Model, and the Comprehensive Model that incorporated the Complex Model and included sleep hygiene. The results indicate the SOC Sleep Quality Model had the best model fit. Rumination acting as a mediator did not strengthen the relationship between SOC and sleep quality, and sleep hygiene did not strengthen the overall model fit. It is possible that SOC may act as a mediator between rumination and sleep quality. More research is needed to determine the relationship between SOC and sleep quality and SOC and rumination. Sleep specialists and health educators may provide better resources for patients with sleep quality problems. The improvement of sleep quality will lead to better overall health and daily functioning.
