Reduced Ability to Make Decisions: a Study That Observe Differences in Patients With Fibromyalgia and Healthy Control

Sponsor: Vrije Universiteit Brussel

Summary

The literature has identified impairments in various cognitive functions, including learning, memory, attention, psychomotor speed, executive function, and working memory. However, only a few studies to date have investigated impairment in the decision-making process. The aim of this study is to evaluate decision-making skills in a group of patients with fibromyalgia and compare these results with a group of healthy controls. Specifically, investigators will evaluate four hypotheses: 1. Patients with fibromyalgia may show disadvantageous decision-making in contexts of emotional decision-making and may persevere more in their wrong choices. For this reason, investigators hypothesize that patients with fibromyalgia will more frequently choose the disadvantageous decks than the healthy control group in the Iowa Gambling Task. 2. Secondly, investigators hypothesize that patients with fibromyalgia need more time to make their choice. Consistent with this hypothesis, researchers expect to find significant differences in the average time taken by the participant to make a choice in the Iowa Gambling Task. 3. The third hypothesis is that patients with fibromyalgia may have greater difficulty inhibiting automatic responses, which may lead to longer reaction times in the Stroop task. Investigators also hypothesize that stimuli with negative emotional valence (related to the typical pain experience in fibromyalgia) may have a greater effect on patients with fibromyalgia than on healthy controls (longer reaction time in the emotional Stroop Task compared to healthy controls). 4. Finally, investigators hypothesize that anxiety, depression, sleep quality, pain, decision-making style and social support may be related to worse performance in ability-based tasks.
