The aim of the study was to compare parents' experience of a routine ultrasound examination in the second trimester, when a choroid plexus cyst/cysts (CPC) were found (Study group; n = 22), with matched controls where no fetal deviations were identified (Control group, n = 66). All the parents had participated in a larger cohort study. The instruments used for measuring anxiety were STAI-state/trait, sense of coherence (SOC) and Parents' Expectations, Experiences, Reactions to an Ultrasound examination during pregnancy (PEER-U, State of Mind Index). Regarding the SOC and STAI-state/trait no significant differences were found between the cases and controls or within the respective group before and after the ultrasound examination. The cases had an increase in anxiety (more anxious) as measured by the instrument PEER-U after the examination, while the controls showed a significant better level of State of Mind Index (less anxious) after the examination, compared to before. Therefore PEER-U can be a more reliable instrument when studying state of mind (anxiety) in connection with ultrasound examinations, and as it is specific for this situation it does not appear to be time dependent.
该研究的目的是比较在孕中期发现脉络丛囊肿（CPC）的孕妇（研究组；n = 22）与未发现胎儿异常的匹配对照组（对照组，n = 66）的父母对常规超声检查的体验。所有父母都参与了一项更大规模的队列研究。用于测量焦虑的工具包括状态-特质焦虑量表（STAI）、心理一致感（SOC）以及《孕期超声检查时父母的期望、经历和反应》（PEER-U，心理状态指数）。关于心理一致感和状态-特质焦虑量表，在病例组和对照组之间以及超声检查前后各自组内均未发现显著差异。与检查前相比，检查后通过PEER-U工具测量发现病例组的焦虑有所增加（更焦虑），而对照组的心理状态指数显著改善（焦虑减轻）。因此，在研究与超声检查相关的心理状态（焦虑）时，PEER-U可能是一种更可靠的工具，并且由于它针对这种情况具有特异性，似乎不受时间影响。
