Introduction: Menstruation is often accompanied by pelvic pain, nausea, diarrhea or headaches that can affect the quality of life during that period. Objective: To design and validate a specific questionnaire to measure the quality of life related to menstruation. Methods: A questionnaire -CVM-43 has prepared to assess the impact of menstruation on the quality of life for women during that period. Content validity was carried out by consensus of six expert judges and contributions from 30 women. After debugging the questionnaire and passing the pilot test, the CVM-22 was ran to 215 women aged 18 to 35 years. The reliability of the questionnaire was obtained by applying aCronbach, construct validity by factor analysis and feasibility by the percentage of items answered and time of completion. Results: Three factors were identified in the exploratory factor analysis (KMO= 0.910, X2= 2384.54, df= 231 and p< 0.000), which were later confirmed by the confirmatory factor analysis with 53.94% variance. The test-retest reliability was 0.9 and the total reliability was 0.917. The average time of completion was 2.06 ± 0.37. Conclusion: CVM-22 presents good feasibility, reliability and validity to assess the quality of life of Spanish-speaking menstruating women. Nevertheless, it is necessary to perform new analyzes of the questionnaire with older population and different sociodemographic profiles, and to evaluate the scale sensitivity in order to consolidate CVM-22 validation.
