This non-interventional study aims to validate the French version of a meningioma-specific quality-of-life questionnaire (MQOL-FR) and to describe health-related quality of life in adults diagnosed with an intracranial meningioma. Participants will be invited to complete online questionnaires through a secure REDCap link. After reading the study information and recording their non-opposition, participants will complete: (1) MQOL-FR (meningioma-specific), (2) EQ-5D-5L (generic health-related quality of life), and (3) FACT-Br (brain tumor-specific quality of life). The questionnaire session takes approximately 30-45 minutes and can be completed in more than one sitting using a REDCap access code. There is no additional visit and no change in usual care. The study will recruit adults (≥18 years) with a meningioma diagnosis based on imaging and/or confirmed by surgery, through the GHU Paris-Sainte-Anne neurosurgery clinic and through patient/community networks. The goal is to obtain 100 fully completed MQOL-FR questionnaires suitable for psychometric analyses.
