Postmenarchal adults between 19 and 60 years with monthly menstruation
Interventions
The MEK-APP is a mHealth application to evaluate menstrual complaints like heavy menstrual blood loss and dysmenorrhea. The MEK-APP is a calendar and facilitates daily monitoring of pain intensity using a Visual Analogue Scale (VAS), the amount of blood loss through a pictorial blood loss assessment chart (PBAC), and the impact of these complaints on daily life. The MEK-APP followed the waterfall methodology for software development and the usability was evaluated by both adults and adolescents(4). Furthermore, the MEK app has been approved by the privacy and security officers of Amsterdam UMC
After registration for this study via www.mijnmenstruatie.nl (which has also been approved by the privacy and security officers of Amsterdam UMC), participants received the first digital questionnaire. This questionnaire consisted of a baseline questionnaire, the electronic self bleeding assessment tool (e-self-BATH) and the Menstrual Health Literacy questionnaire. After using the MEK-app for at least one month, participants received an e-mail with the second questionnaire. This questionnaire consisted of the Menstrual Bleeding Questionnaire; Period ImPact and Pain Assesment; Pelvic Pain Impact Questionnaire; ENDOPAIN-4D; Endometriosis Health Profile 5 and iMTA Productivity Cost Questionnaire.
