The questionnaire consists of questions organized into thematic sections. It starts with the daily experience of cystitis and its impact (frequency, symptoms, and aspects of life affected), continues with the medical history and course of management (how long have you suffered from it, professionals consulted, possible diagnosis and diagnostic tools, strategies used to cope with symptoms). It then includes a section on lifestyle and habits (contextual factors, daily routine, possible intolerances) and a section on the intimate and sexual area, to explore possible correlations between relationships, pain, and intimate hygiene practices.
