Investigation of the Cultural Adaptation, Validity, and Reliability of the Turkish Version of the Central Aspects of Pain (CAP) Questionnaire

What this Trial Is About

Researchers are studying the Turkish version of the Central Aspects of Pain (CAP) questionnaire, which is designed to assess features of nociplastic pain in people with musculoskeletal disorders such as osteoarthritis, back pain, and fibromyalgia. This study aims to culturally adapt, validate, and test the reliability of this questionnaire for Turkish-speaking patients. Chronic pain in these conditions is often linked to nervous system changes that are not fully explained by physical problems alone. The study involves administering the Turkish CAP questionnaire along with other related questionnaires that assess biopsychosocial factors, anxiety, depression, pain catastrophizing, central sensitization, and pain quality. Participants include adults with osteoarthritis, back pain, or fibromyalgia who will complete these assessments over a three-month period. There is no drug or device intervention, as this is an observational study focused on questionnaire validation. Participants will be involved for at least three months during which they will complete the CAP questionnaire and other related scales. Researchers will evaluate the questionnaires' validity and reliability based on responses. The primary outcome measured is the CAP questionnaire score at three months, with secondary outcomes including several other pain and psychological assessment tools. This study helps improve tools for understanding and managing chronic pain in Turkish-speaking patients.
