Constipation - Functional

Brief summary

The investigators will conduct a validity and reliability study of the Wexner Constipation Questionnaire, used for constipation, in Turkish. For this purpose, investigators will administer the Wexner Questionnaire, translated from English to Turkish, and the accompanying Constipation Quality of Life Scale to 200 participants. Investigators will repeat the Wexner questionnaire for some participants after two weeks.

Detailed description

To assess the cultural adaptation, validity, and reliability of the eight-question Wexner Constipation Questionnaire, the questionnaire was first translated from English to Turkish, then back from Turkish to English, and finally back from English to Turkish. The questionnaire was finalized with the collaboration of an internal medicine specialist and a gastroenterologist to prepare the Turkish version. It will then be administered to a minimum of 200 participants, along with the Constipation Quality of Life Questionnaire, previously validated and reliable in Turkish and used for constipation. For reliability, the questionnaire will be repeated for a portion of the participants after two weeks.
