The scores in all sleep dimensions of the MOS-sleep were higher in CPP (more disturbances) compared to pain free patients, and differences were observed among the three groups of PCP, with FM most severely affected.
Three main groups of women with CPP were identified: Cluster 1 (n = 35) had moderate severity of pain, with poor average and present pain intensity; Cluster 2 (n = 14) had a long duration of symptoms/diagnosis, the worst current pain and worst physical, emotional and social functions; Cluster 3 (n = 11) had the shortest duration of pain and showed the best evidence of coping with low (good) physical, social and emotional scores.
