Multimodal Recruitment for an Internet-Based Pilot Study of Ovulation and Menstruation Health

The Ovulation and Menstruation Health (OM) Pilot Study, conducted between September 2017 and March 2018, used multimodal recruitment strategies to gather a diverse cohort of 438 women, of which 247 completed the survey. The study aimed to understand the prevalence of polycystic ovary syndrome (PCOS) and was successful in achieving its target recruitment in a short time period. The mean age of participants was 27 years, and 14.6% reported a physician diagnosis of PCOS. The recruitment methods, which included a clinical population, a community fair, and the internet, were associated with race/ethnic diversity and completion of the survey. The highest enrollment and completion rates were among those recruited via the internet (91.4%) and community fairs (98.4%), compared to in-clinic (65.1%).
