Pregnancy-related anxiety has been linked to many maternal and child-related negative outcomes. However, there is an absence of free, well-validated screeners for this condition. The Pregnancy-related Anxiety Scale–Screener (PrAS-Screener) was evaluated using robust Rasch methodology. This study also aimed to develop a shorter version to meet the need of settings governed by professional guidelines stipulating the use of brief instruments. Data from 400 pregnant women (M_age = 27.82, SD = 5.38) were subjected to Rasch analyses and the resulting Rasch models confirmed in a second sample (N = 400, M_age = 26.29, SD = 4.95). After minor modifications, the original 15-item PrAS-Screener demonstrated good fit, unidimensionality, excellent targeting, invariance, and internal consistency. After removal of items with content overlap, an 11-item version was developed, with this version showing good fit, unidimensionality, reasonable targeting, and sound internal consistency. The PrAS-Screeners show promise as psychometrically sound clinical scales for screening pregnancy-related anxiety.

与怀孕相关的焦虑与许多与母婴相关的负面结果有关。然而，目前还没有针对这种情况的免费、经过充分验证的筛选器。使用稳健的 Rasch 方法评估妊娠相关焦虑量表筛选器 (PrAS-Screener)。本研究还旨在开发一个较短的版本，以满足由规定使用简短工具的专业指南管理的设置的需要。对 400 名孕妇（M_年龄= 27.82，SD = 5.38）的数据进行了 Rasch 分析，并在第二个样本（N = 400，M_年龄= 26.29，SD= 4.95）。经过细微修改后，原来的 15 项 PrAS-Screener 表现出良好的拟合度、单维性、出色的靶向性、不变性和内部一致性。去除内容重叠的条目后，开发了一个11条目的版本，该版本具有良好的拟合度、单维性、合理的针对性和良好的内部一致性。PrAS-Screeners 显示出作为筛查妊娠相关焦虑的心理测量学合理临床量表的前景。
