Fibromyalgia is a common chronic musculoskeletal disorder characterized by the dryness of the cornea and eyes or mouth, paresthesia, nonrestorative sleep (NRS), premature fatigue, and multiple tender points with scattered and symmetric distribution (
1). The symptoms of fibromyalgia include scattered and multifaceted musculoskeletal pain with multiple tender points, sleep disorder, fatigue, long muscle spasms, limb weakness, muscle inflexibility, dysphagia, bowel and bladder impairment, headache, and cognitive-mood disorders, including short-term memory impairment, poor concentration, depression, tension, anxiety, and morning joint stiffness (

3). In addition to pervasive pain, patients with fibromyalgia complain about impaired cognitive functions, anxiety, and depression (
4). Living with chronic pain involves considerable affective stress that limits patients’ emotional and affective capacity and ultimately weakens their morale, creating a sense of frustration, helplessness, and depression (
5).
The literature reports the frequency of mood disorders in patients with fibromyalgia at 28.75% (
6). Given the widespread depression and its interference with therapy and the reduction of pain and frustration in patients with fibromyalgia, treatment priorities must include one-dimensional (axial) biological therapies and treatment of depression and other mental disorders (
7). Studies confirm psychological disorders in patients with fibromyalgia (
6,
8). Henao-Perez et al. (
6) reported that a significant percentage of fibromyalgia patients experience depression and anxiety, and fibromyalgia has a great impact on the physical and mental health of patients. Galvez-Sanchez et al. (
8) reported that fibromyalgia reduces performance in physical, psychological, and social spheres and has a negative impact on cognitive performance, personal relationships, work, and activities of daily living.
In terms of therapeutic interventions, there have been few documented attempts in psychotherapy to improve the psychological health of individuals suffering from depression and severe fibromyalgia symptoms. Currently, numerous theoretical perspectives with different approaches are being used to improve the psychological condition of patients (
9). The basic assumption of intensive short-term dynamic psychotherapy (ISTDP) theories concerning mental disorders is that the mental derangements making up the clinical picture of individuals with different mental disorders are a reflection of the pathological features of their underlying psychological constructs (
10). Therefore, treatments that alter psychological structures and mental organization lead to changes in their pathological personality traits and mental disorders (
11).
Intensive short-term dynamic psychotherapy aims to determine the meaning, function, and consequences of psychopathological symptoms of these patients based on the main themes of internal conflicts and their changes (
12,
13). The identification, interpretation, and resolution of the main conflicts enable patients to identify, predict, modify, or control their feelings and behaviors, thereby improving the methods of resolving the internal conflicts and the psychopathological symptoms reflecting these conflicts (
14). The noteworthy outcomes of ISTDP include the improvement of emotional relationships with important others. Intensive short-term dynamic psychotherapy stresses individuals’ past and present emotional relationships and attachment styles (
15,
16).
Research has shown that mindfulness-based stress reduction (MBSR) techniques enable individuals to learn non-judgmental and non-critical observation together with compassion toward themselves and others (
17,
18). They learn to observe stressful and unhappy thoughts and emotions and identify negative thought patterns before getting drawn into a vicious cycle. Mindfulness-based stress reduction is a psycho-educational intervention that helps individuals practice mind-body meditation with the aim of reducing stress and improving health (
19). Mindfulness means paying attention in a special, purposeful, and non-judgmental way (
20). In this model, mindfulness means intentionally focusing one’s attention on the ongoing experience in a non-judgmental and receptive way (
21). The comparison of two interventions of a stress-reduction program based on mindfulness and short-term dynamic psychotherapy was one of the most important innovations of the audience study, which has not been addressed in previous studies. The large number of referrals to counseling centers due to depression and finding an effective way to improve it was the most important reason for this comparison.
