Repetitive Thinking in FibroMyalgia and Attentional Bias

Completed

• Conditions: Chronic Pain

• Registration Number: NCT03466892
• Lead Sponsor: Centre Hospitalier Universitaire, Amiens

Brief Summary

Theoretical models of chronic pain hypothesize a privileged treatment of pain-related information that would be the basis of avoidance behaviors in chronic pain. This privileged treatment, also called attentional bias, has been found experimentally in chronic pain. Meta-analyses confirmed that but leaded the question of the difference found between bias in period of attention orientation and bias in period of maintained attention. One of the hypotheses is to consider one or more cognitive processes that would "fix" the attention around significant perceived problems and that would hinder the attentional disengagement and the reorientation of attention towards neutral or positive stimuli. In view of the scientific literature in psychopathology but also in chronic pain we think that the negative repetitive thoughts (RNT) variable is one of these processes. So the investigators want to better understand the difference of attentional bias at different moments of the attentional process by interrogating the Repetitive Thinking variable. More specifically the investigators test the Attentional Bias hypothesis in Fibromyalgia. Patient with Fibromyalgia will be recruited at the Pain Center of CHU-Amiens. Patients will complete different scales and also the visual probe task. First, the investigators hypothesize the attention bias for pain-related information in the FM group is correlated with the level of negative repetitive thinking in the maintained attention phase. Second, the investigators hypothesize the attention bias is more important in the attention maintenance phase (1250 ms) than in the attention orientation phase (500 ms).
