Abstract Objective To evaluate the reliability of a one-week versus a four-week recall period of the Medical Outcomes Study Sleep Scale MOS-SS in patients with fibromyalgia FM . Methods The MOS-SS was administered by mail to patients with a confirmed diagnosis of FM and a current pain rating of 2 0-10 point numerical rating scale recruited through newspapers support groups and the Internet. Reliability of MOS-SS subscale domains was evaluated using test-retest methodology separated by a 1-3 day interval for the 4-week recall period and a 7-day interval for the 1-week recall period. Patient Impression of Change was evaluated for sleep and for patients with no change the intraclass correlation coefficient ICC and the Pearson correlation coefficient was calculated for MOS-SS subscales. Results Of 129 patients enrolled were female mean age was years self-rated FM severity was moderate-to-severe in of patients. MOS-SS .
