Aims: The purposes of this cross-sectional preliminary study were to examine the relationships between subjective and objective assessments of sleep quality and to analyse the predictors of fatigue in Italian patients diagnosed with Fibromyalgia (FM). Materials: Participants completed a sociodemographic questionnaire and psychometric scales measuring depression (Brief Symptom Inventory-BSI) and perceived fatigue (Checklist of Individual Strength –CIS20). Self-reported measures of sleep were the Sleep Disorder Questionnaire – SDQ; and a standard sleep Diary. Objective information about sleep was recorded for seven days through actigraphy (AMI Motionlogger Watch). Methods: After a medical visit at the Fibromyalgia unit of the university hospital the physicians invited female patients to wear an actigraph for one week. After seven days participating patients returned the actigraph and answered a structured interview conducted by a trained junior psychologist through which the psychometric scales were administered. Results: The majority of the 21 FM patients interviewed (76.2%) described their sleep quality as poor or very poor (rating sleep quality on 4 point Likert scale), the mean for the whole sample being 3.10 (SD=.89). All patients reported insomnia complaints, and 18 (81%) met the criteria for a diagnosis of Difficulties Initiating and Maintaining Sleep (DIMS). The patients’ perception about the number of hours slept (M=5.7) was significantly lower than the actigraphic data (M=6.8). Total Sleep Time measured through actigraphy was directly correlated with the intensity of fatigue perceived (r=.481; p<0.05) and multiple regression considering also Total Time in Bed, depression, and self-management type, showed that it was the variable that gave a major and unique contribute to the prediction of perceived fatigue. Conclusions: These findings confirm the high prevalence of sleep disturbances in FM, and suggest that sleep duration play an important role in the perceived fatigue severity. Intervention programs for FM should include sleep regulation.
