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

Iowa gambling task (IGT)

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 and depression may be related to worse
 performance in ability-based tasks.
