As prenatal genetic testing technologies have become both easier and more accessible, women are increasingly choosing prenatal genetic testing for a reason that is largely unexamined in the clinical literature: preparation. This reasoning, offered not only from pregnant women but frequently from testing laboratories and health care providers, reflects long-held assumptions that prenatal genetic results-properly delivered and followed with information, clinical surveillance, and/or social supports-prepare families for a child with a genetic condition, and even improve health and social outcomes for children and families. But these assumptions remain unexamined, since there are no clear definitions or recommendations for prenatal preparation. Preparation may refer to several overlapping ways in which prenatal information may change parents' approach to the rest of the pregnancy, including: (a) clinical activities, including surveillance, interventions, and delivery planning; (b) social and informational support, such as interacting with patient support groups and gathering information about quality of life; and (c) psychological "coping" or adjustments to the reality of raising a child with a genetic condition. These meanings and activities intersect and influence one another and form a foundation for postnatal family adaptation, but they are rarely parsed out in studies examining the impact of prenatal diagnosis. Based on previous work delineating conceptual models as middle terms between theory and reality, we are building a conceptual model that incorporates an empirical understanding of meanings and actions encompassed by prenatal preparation. Comparing diverse families' expectations with the resources they are offered can identify (mis)matches between priorities and approaches.
随着产前基因检测技术变得更加容易和普及,越来越多的女性选择进行产前基因检测,其原因在临床文献中基本上没有得到探讨:准备。这种推理不仅来自孕妇,而且经常来自检测实验室和医疗保健提供者,反映了长期以来的假设,即产前基因检测结果——如果正确提供,并伴随着信息、临床监测和/或社会支持——可以为有遗传条件的孩子做好准备,甚至可以改善孩子和家庭的健康和社会结果。但这些假设仍未得到检验,因为产前准备没有明确的定义或建议。准备可能指的是产前信息以几种重叠的方式改变父母对妊娠剩余时间的态度,包括:(a)临床活动,包括监测、干预和分娩计划;(b)社会和信息支持,例如与患者支持团体互动并收集有关生活质量的信息;(c)心理“应对”或对生育有遗传条件的孩子的现实的调整。这些含义和活动相互交叉并相互影响,为产后家庭适应奠定了基础,但在研究产前诊断影响时很少将其分解。基于先前描述概念模型作为理论和现实之间的中间术语的工作,我们正在构建一个概念模型,该模型纳入了对产前准备所包含的意义和行为的实证理解。将不同家庭的期望与他们提供的资源进行比较,可以识别出优先事项和方法之间的(不)匹配。
