Clinical Trial 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Fibromyalgia Impact Questionnaire (FIQ)	The FIQ is a solid, worldwide-used questionnaire with a history of 20 years consisting of three domains (functional domain, physical symptom domain, and mental symptom domain). It is composed of 10 questions. The first question contains 11 items related to the ability to perform large muscle tasks - each question is rated on a 4 point Likert type scale. Items 2 and 3 ask the patient to mark the number of days they felt well and the number of days they were unable to work (including housework) because of fibromyalgia symptoms. Items 4 through 10 are horizontal line-ar scales marked in 10 increments on which the patient rates work difficulty, pain, fatigue, morn-ing tiredness, stiffness, anxiety and depression.; The internal consistency of the FIQ is high (Cronbach's Alpha> 0.80). The scale is translated and validated in French and Dutch.	Baseline (cross sectional)
Other	The Multidimensional Scale of Perceived Social Support (MSPSS)	The MSPSS assess an individual's perception of the social support he or she receives from family, friends, and significant others. It is a self-report measure and contains 12-items, rated on a 7-point Likert-type scale, ranging from 1 "very strongly disagree" to 7 "very strongly agree." The scale was divided into 3 subscales: family, friends, and significant other, with each section consisting of 4 items. The scale reports the three subscale scores and an overall total score. The average item rating is reported as the score for the subscales and for the total score.; The internal consistency of the MSPSS is excellent (Cronbach's Alpha > 0.89). The scale is translated and validated in French and Dutch.	Baseline (cross sectional)
Other	Brief Pain Inventory (BPI)	The BPI was developed to provide a quick and easy means of measuring pain intensity and the extent to which pain interferes in the lives of the pain sufferers. Using this measure, respondents rate their worst, least, average, and current pain intensity and rate the degree to which pain inter-feres with 7 domains of functioning (general activity, mood, walking ability, normal work, rela-tions with other persons, sleep, and enjoyment of life) on a scale of 0 to 10.; In patients with chronic non-malignant pain the internal consistency (Cronbach's Alpha) was .85 for the intensity scale and .88 for the interference scale.; The scale is translated and validated in French and translated in Dutch.	Baseline (cross sectional)
Other	General Decision-Making Style (GDMS)	The GDMS was designed to assess how individuals approach decision situations. It distinguishes between 5 decision styles: a rational style, an avoidant style, a dependent style, an intuitive style and a spontaneous style. The scale consists of 25 items, each item has a score ranging from 1 to 5 (1= strongly disagree to 5= strongly agree).; The internal consistency reliability (Cronbach's alpha) range between 0.62 and 0.84 for the five styles.; The scale is translated and validated in French and Dutch.	Baseline (cross sectional)
Other	Hospital Anxiety and Depression Scale (HADS)	The HADS is a two-dimension scale developed to identify depression and anxiety among physi-cally ill patients. The HADS consists of 14 items, divided into two 7 subscales: anxiety (items reflect a state of generalized anxiety) and depression (focus on the concept of anhedonia). The respondent rates each item on a 4-point scale, higher scores indicate greater levels of anxiety or depression.; The internal consistency of the HADS range from adequate to excellent (Cronbach's Alpha 0.67-0.93).; The scale is translated and validated in French and Dutch.	Baseline (cross sectional)
Other	Medical Outcomes Study Short Form 36 (SF-36)	The SF-36 is a generic patient-reported outcome measure that quantifies health status and measures health-related quality of life. It consists of 36-item measure divided into 8 subscales and 2 composite domains. The 8 subscales are: physical functioning, role limitations due to physical problems, general health perceptions, vitality, social functioning, role limitations due to emotion-al problems, general mental health and health transition.; The internal consistency of the SF-36 in chronic pain population is good (Cronbach's Alpha 0.76).; The scale is translated and validated in French and Dutch.	Baseline (cross sectional)
Other	Insomnia Severity Index (ISI)	The ISI is a 7-item self-report questionnaire assessing the nature, severity, and impact of insom-nia. the dimensions evaluated are: severity of sleep onset, sleep maintenance, and early morning awakening problems, sleep dissatisfaction, interference of sleep difficulties with daytime func-tioning, noticeability of sleep problems by others, and distress caused by the sleep difficulties. A 5-point Likert scale is used to rate each item (e.g., 0 = no problem; 4 = very severe problem), yielding a total score ranging from 0 to 28. The total score is interpreted as follows: absence of insomnia (0-7); sub-threshold insomnia (8-14); moderate insomnia (15-21); and severe insomnia (22-28).The internal consistency of the ISI range between good and excellent (Cronbach's Alpha 0.76 - 0.91).; The scale is translated and validated in French and Dutch.	Baseline (cross sectional)
Primary	Iowa gambling task (IGT)	This task is designed to assess cognitive function in emotional decision-making. It is a computerized decision-making task that involves uncertainty, risk assessment, and the evaluation of both reinforcement and punishment.	Baseline (cross sectional)
Secondary	Stroop task and Emotional Stroop task	The Stroop test is an instrument for assessing executive functions and aims to measure an individual's ability for selective attention, cognitive flexibility, and inhibition of automatic answers.; The Stroop task can also be manipulated to examine how emotional stimuli disrupt colour-naming performance (Emotional Stroop task).
