Associated scholarship(s):22/16124-0 - Development of a manual for the cosmin reporting guidelines for studies on the measurement properties of proms and translation of the cosmin reporting guideline and its manual into Brazilian Portuguese, BE.EP.DR


Introduction: Dysmenorrhea is defined as menstrual pain of uterine origin and can often cause functional disability and generate presenteeism at school and at work. Despite this, no Patient-Reported Outcome Measure (PROM) was developed to assess functionality and presenteeism or validated for women with dysmenorrhea in Brazil. This research will be divided into two subprojects entitled "Translation, cross-cultural adaptation and evaluation of measurement properties of Dysmenorrhea Symptom Interference (DSI) into Portuguese/Brazil" (subproject 1) and "Development and evaluation of measurement properties of two PROMs for evaluation of functionality and presenteeism related to dysmenorrhea" (subproject 2). Objectives: Subproject 1 - Cross-culturally adapt the DSI to Portuguese/Brazil and evaluate its measurement properties; Subproject 2 - Develop two PROMs for functionality and presenteeism related to dysmenorrhea and evaluate their measurement properties. Methods: Both subprojects will be online and methodological in approach, but only subproject 1 will be multicentric. The sample of subproject 1 will be composed of a committee of up to 10 experts in women's health and 10 to 20 Brazilian women aged 14 to 42 years and with dysmenorrhea (target population) to assess content validity, and at least other 200 women from the target population. For subproject 2, the sample will have the same characteristics as subproject 1, but with the inclusion of 3 researchers with experience in qualitative studies, 5 women for the evaluation of the interview script, 10 to 20 women for the evaluation of the development of the instruments and 10 to 20 women to test the pre-final versions of the instruments. Will be used: cognitive interview script, sample characterization questionnaire, DSI, Numerical Rating Scale (NRS), WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) and Stanford Presenteeism Scale (SPS-6). In both subprojects, individual semi-structured cognitive interviews will be carried out with experts and target population via recorded phone call and data collection via Google Forms.
