Category B: Vermont Pregnancy Risk Assessment Monitoring System (PRAMS)

描述（由申请人提供）：佛蒙特州怀孕风险评估监测系统旨在改善母亲及其婴儿的健康。这是一项针对新妈妈的调查，询问她们在怀孕前、怀孕期间和怀孕后不久的经历和行为。每个月从出生档案中抽取新妈妈的样本，并按出生体重分层。母亲首先收到一封信，通知她将收到一份调查报告。第一封调查邮件会在四天后发送，并附上描述项目的求职信。它还包括知情同意书、问答手册、资源信息、返回信封和作为奖励的小礼物。两周后，将向未答复的人发出一封提醒信。第二个调查包在发痒信两周后寄出，然后再过两周寄出第三个调查包。在最后一次邮寄一周后，将与未回复邮件的人进行电话联系。在五周的时间里，我们给这位母亲打了多次电话，试图说服她完成一次电话采访。

DESCRIPTION (provided by applicant): The Vermont Pregnancy Risk Assessment Monitoring System is designed to improve the health of mothers and their babies. It is a survey of new mothers that asks questions about experiences and behaviors before, during, and shortly after pregnancy. A sample of new mothers is selected each month from the birth file, and stratified by birth weight. The mother is first sent a letter informing her that she will be receiving a survey. The first survey mailing is sent four days later with a cover letter that describes the project. It also includes the informed consent, a question and answer brochure, resource information, return envelope and a small gift as an incentive. A reminder letter is sent two weeks later to non- respondents. A second survey packet is mailed two weeks after the tickler letter, and then a third survey packet after two more weeks. One week after the final mailing, telephone calls are initiated with any mail nonrespondents. Multiple phone calls over five weeks are made in an attempt to reach the mother and persuade her to complete a telephone interview.
