Psychometric Validation of the MQOL-FR and Descriptive Assessment of Quality of Life in Patients With Meningiomas

Meningiomas are common intracranial tumors and may substantially affect psychological, social, and functional well-being, including in patients managed conservatively. However, validated meningioma-specific quality-of-life tools are limited. The MQOL questionnaire was originally developed as a patient-centered, meningioma-specific instrument; a prior French translation/adaptation and pilot evaluation has been conducted. This study (MenQOL2) is designed to complete an in-depth psychometric validation of the French version (MQOL-FR) in a larger cohort and to provide a descriptive assessment of quality of life in French patients with meningioma.

This is a single-center, non-interventional, questionnaire-based study with a single assessment (no follow-up). Adults (≥18 years) with intracranial meningioma diagnosed on imaging and/or confirmed surgically will be invited. Exclusion criteria include inability to complete questionnaires independently, insufficient French comprehension, pregnancy/breastfeeding, legal deprivation of liberty, and individuals under compulsory psychiatric care.

Participants receive study information (in clinic when applicable, otherwise by email) and access a secure REDCap link. Non-opposition is recorded online prior to questionnaire completion. Participants complete MQOL-FR (70 items), EQ-5D-5L, and FACT-Br. The total completion time is estimated at 30-45 minutes; completion may be split into multiple sessions using a REDCap-provided access code. Data are collected directly in REDCap and stored in pseudonymized form.

Primary outcome is psychometric performance of MQOL-FR, including dimensionality/structural validity, internal consistency (e.g., Cronbach's alpha), construct and convergent validity against EQ-5D-5L and FACT-Br, completeness rates, and floor/ceiling effects. Secondary objectives are descriptive and exploratory: to summarize MQOL-FR, EQ-5D-5L, and FACT-Br scores in the overall cohort and compare subgroups (e.g., WHO grade, sporadic vs progestin-associated, symptomatic vs asymptomatic, skull base vs convexity, tumor size, single vs multiple lesions, and management strategy). Exploratory modeling (ANCOVA/regression) will be used to assess factors associated with MQOL-FR scores. The targeted analyzable sample is 100 complete MQOL-FR responses; based on prior completion rates, approximately 238 patients will be contacted to achieve this target. In accordance with the collaboration with the original MQOL developers, de-identified score data may be shared for scientific purposes.
