The stress generation literature has established a bidirectional relationship between depression and stressors. Not only do stressful life events predict depressive episodes, but depressive history is also linked to increased, future stressors. One mechanism that has received little attention to account for this relationship is sleep. Sleep difficulties are well associated with depression, both as a predictive and maintenance factor. Beyond depression, sleep disruption is also a factor in various stressful events, from an increased risk of accidents to higher reports of interpersonal conflict. The present study explored the role of sleep quality and sleep duration to account for depression’s association with stressors. Ninety-six college students reported on their depressive symptoms before undergoing a two-week, online diary, where they reported on sleep quality, sleep duration, and the number of stressors experienced. Two, generalized structural equation models (GSEMs) were used to test the unique relevance of both sleep quality and duration, to account for baseline depressive symptoms’ predicting average differences in stressors over the diary. Within each GSEM, a multilevel model was used to explore the daily, within-person association of either sleep quality or duration and the number of stressors reported. Baseline depression was predictive of poorer sleep quality and more stressors. Moreover, sleep quality also mediated the effect of depression on stress generation, accounting for 9.97% of the variance. On a daily level, poorer sleep quality and less sleep duration the night before also predicted more stressors the next day. However, sleep duration was not associated with depression, nor did it mediate the depression’s relationship with stress generation. The results suggest that both sleep quality and duration may help explain future stress generation. Sleep quality, in particular, appears to be a relevant mechanism in the prediction of future stressors from depression. Sleep difficulties may represent a pivotal area of research and intervention in breaking the cycle between depression and stress generation.
