The present study investigated the relationship between stress and sleep. A self-report measure was used to assess three domains: environmental events, personality mediators, and emotional responses. It was hypothesized that one or more of the domains would predict seven different aspects of sleep. 227 college students completed the Derogatis Stress Profile and the Sleep Questionnaire. Analysis indicated that scores on emotional response were the best predictor of five different sleep aspects: depth of sleep, difficulties in waking up, quality and latency of sleep, negative affect in dreams, and sleep irregularity. Presence of environmental events was the best predictor for the length of sleep only. It was concluded that research looking at the effects of stress on sleep must consider all three components of stress and that perhaps the emotional response to stress is the best predictor of sleep complaints.
