Background: Due to uncertainty regarding chronic pain in Fibromyalgia (FM) patients, there has been a growing interest in social comparison and its influence on emotional responses.Aims: to analyze profiles in FM patients according to pain perception, social comparison strategies and anxiety and depression. Methods:The sample consisted of 131 FM outpatients (Mean age: 50.15, SD = 11.1). Two scales were used: the Social Comparison Illness Scale and the Hospital Anxiety and Depression Scale.Results: Two profiles were found by cluster analysis (K-means method): one (66%) with a higher level of pain perception, anxiety and depression and greater use of upward contrast and downward identification social comparison; and another (34%) with lower levels of pain perception, anxiety and depression and greater use of upward identification and downward contrast. Conclusion:These profiles underline the interest in social comparison strategies and their role in FM.
