For those women who have time to learn more about the study immediately following their obstetrics appointment at BWH, our Research Assistant will take women into a private room within the obstetrics clinic and provide them with general information about the study. If a woman is interested, we will ask the woman a set of screening questions to assess their eligibility. The screening questions will not include any personal identifying information and will only be collected to determine eligibility and response rates. If eligible for participation in our study, we will collect the eligible woman's contact information and provide the woman with an informed consent form to be reviewed and signed either at that time to our Research Assistant or returned to us by mail using a provided stamped, addressed envelope within 2 weeks of having received the form. Description of the study, confirmation of contact information, administration of the screening questionnaire, and receipt and review of consent documents will occur similarly by phone for those women who were not available to learn more about the study immediately following their obstetrics visit, but who expressed interests in learning more about the study at a later time point.
