Objective: The current study examined sleep disturbance (i.e., sleep duration, sleep quality) as a correlate of stress reactivity and pain reactivity.

Design and Outcome Measures: An ecological momentary assessment design was used to evaluate the psychosocial functioning of men and women with fibromyalgia or rheumatoid arthritis (N = 49). Participants recorded numeric ratings of pain, the occurrence of a stressful event, as well as positive and negative affect 7 times throughout the day for 2 consecutive days. In addition, participants reported on their sleep duration and sleep quality each morning.

Results: Sleep disruption was not found to be an independent predictor of affect. However, sleep was found to buffer the relationship between stress and negative affect and the relationship between pain and both positive and negative affect.

Conclusion: These results are consistent with a model in which good-quality sleep acts as a biobehavioral resource that minimizes allostatic load. ((c) 2007 APA, all rights reserved).

About FMS Global News

Folllowing Rick Usher's death in December 2008, at his request in September of that year, I had agreed, as his principal contributor and an experienced journalist, to run the FMS Global News service due to his heavy commitments to music and raising research funds through this avenue. Following his sad and sudden death I hope to continue his work as he would have wished.
