This study aims to validate and assess the reliability of the Turkish version of the Paris Pain Questionnaire (PPQ) in patients with coccydynia. The PPQ was developed by Dr. Jean-Yves Maigne as a condition-specific tool to evaluate pain severity and functional limitations in individuals with coccydynia. This study follows a cross-sectional observational design and includes 105 participants. The psychometric properties of the Turkish version will be assessed through internal consistency (Cronbach's alpha), test-retest reliability (intraclass correlation coefficient - ICC), and construct validity. The results will determine whether the PPQ is a valid and reliable tool for use in Turkish-speaking populations with coccydynia.

* Ability to read and understand Turkish
* Willingness to participate and provide informed consent
Exclusion Criteria:
* Presence of other conditions causing pelvic or rectal pain (e.g., endometriosis, ectopic pregnancy, hemorrhoids, rectal carcinoma)
* Severe psychiatric disorders (e.g., psychosis, major depression within the last 30 days)

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
