To describe the development and content validity testing of the Maternal Fetal Triage Index (MFTI), a standardized tool for obstetric triage.
Online survey.
Participants included 15 registered nurses, 15 certified nurse-midwives, and 15 physicians from across the United States who provided maternity care.
A convenience sample of experienced clinicians was used as content validators for the MFTI. An item content validity index (I-CVI) was computed for the tool's items and a scale content validity index (S-CVI) was computed for the tool's scale based on the responses submitted via the online survey. Two rounds of content validation occurred.
In the first round of testing, a total of 12 of 61 items in the MFTI did not meet the I-CVI threshold of greater than 0.78 because of disagreement about clinical condition (75%) or priority level placement (25%). In the second round of testing, all but 3 of the 69 content items in the revised version of the MFTI had I-CVI thresholds greater than 0.78. These 3 items were related to vital sign values. The overall S-CVI score calculated for Round 2 only was 0.95, which was greater than the threshold of 0.90.
The results of the content validity testing of multidisciplinary validators suggest that the MFTI is a valid tool for use in obstetric triage and evaluation settings.
描述母胎分诊指数（MFTI）的开发及内容效度测试，这是一种用于产科分诊的标准化工具。
在线调查。
参与者包括来自美国各地提供产科护理的15名注册护士、15名认证助产士和15名医生。
选取经验丰富的临床医生作为MFTI的内容效度验证者。根据通过在线调查提交的回复，计算该工具各条目的条目内容效度指数（I-CVI）以及该工具量表的量表内容效度指数（S-CVI）。进行了两轮内容效度验证。
在第一轮测试中，MFTI的61个条目中共有12个未达到I-CVI阈值大于0.78的标准，原因是在临床状况（75%）或优先级放置（25%）方面存在分歧。在第二轮测试中，MFTI修订版的69个内容条目中除3个外，其余所有条目的I-CVI阈值均大于0.78。这3个条目与生命体征值有关。仅针对第二轮计算的总体S-CVI分数为0.95，大于0.90的阈值。
多学科验证者的内容效度测试结果表明，MFTI是一种可用于产科分诊和评估环境的有效工具。
