Abstract

IntroductionEndometriosis is a disabling disease impacting on different aspects of reproductive health. The present study aims to develop and evaluate the psychometric properties of a questionnaire to measure the reproductive health in women with endometriosis.Material and methodsThis study used an exploratory mixed-methods design and included three phases. In the first phase, a sample of 20 women with endometriosis participated in semi-structured interviews. In the second phase, item pools were generated. In the third phase, face validity, content validity, and construct validity were assessed. To estimate the reliability of the tool internal consistency and test-retest methods were used.Resultssixty items were included in the psychometric evaluation stage of the scale. After the assessment of the content validity ratio (CVR), content validity index (CVI), and exploratory factor analysis, 15 items were omitted, leaving 35 items in the final scale. The exploratory factor analysis revealed four factors: physical problems, psychological problems, counteracting strategies, and instability of marital life. The reliability, according to Cronbach's alpha was 0.809, and the external reliability, as evaluated by the test-retest method and the intraclass correlation, was 0.825.ConclusionERHQ is a new, valid, and reliable patient-generated instrument to measure the reproductive health in women with endometriosis. It can be used by researchers and health providers to provide a better understanding of the impact of endometriosis on different aspects of reproductive health over time and to meet the needs of patients living with this condition.
