Pain Severity in Fibromyalgia Syndrome

Pain severity and degree will be evaluated with the "Revised Graded Chronic Pain Scale (GCPS-R)". The "Graded Chronic Pain Scale" was created by Von Korff et al (1) to evaluate the severity of pain and disability related to pain in individuals with chronic pain. It has also been revised by the same authors (2). The Turkish validity and reliability study of the GCPS-R was performed by Özden et al (3).

The Fibromyalgia Impact Questionnaire was developed by Burckhardt et al (4). The scale was revised by Bennett et al (5). The Turkish validity and reliability study of the FIQ-R was performed by Ediz et al (6). The structure of the FIQ-R's original questionnaire, based on function, overall effect, and severity of FM symptoms (disease severity) is the same as in the FIQ. However, questions assessing altered function, which were not part of the original FIQ, and questions measuring cognitive impairment, sensitivity, balance, and environmental sensitivity have been added to the FIQ-R. Also, some of the wording, missings, concepts and scoring problems in the original FIQ have been corrected in the FIQ-R. FIQ-R consists of 21 questions in total.

"Tampa Kinesiophobia Scale (TKS)" will be used to evaluate kinesiophobia. The Turkish version was created by Yılmaz et al (7). The scale consists of 17 questions developed to measure the fear of movement and/or re-injury.

Participants' pain concerns will be assessed with the "University of Washington Concerns About Pain (UWCAP)", which was recently developed as a pain self-efficacy measure based on modern scale development approaches. The scale was adapted to Turkish by Saraçoğlu et al (UWCAP-TR-6). "UWCAP-TR-6" consists of 6 questions.

Turkish Short form-12 (SF-12) questionnaire, 12-item generic self-administered instrument that consists of eight subscales relating to various aspects of the QoL: physical functioning, physical role, bodily pain, general health, vitality, social functioning, emotional role and mental health.
