This study aims to assess the validity of maternal recall for several perinatal variables 8-10 years after pregnancy in a twin sample. Retrospective information was collected 8-10 years after the delivery event in a cohort of mothers from the University of Southern California Twin Study (N = 611) and compared with medical records for validity analysis. Recall of most variables showed substantial to perfect agreement (κ = 0.60-1.00), with notable exceptions for specific medical problems during pregnancy (κ ≤ 0.40) and substance use when mothers provided continuous data (e.g., number of cigarettes per day; r ≤ 0.24). With the exception of delivery method, neonatal intensive care unit admission, birth weight, neonatal information, and post-delivery complications were also recalled with low accuracy. For mothers of twins, maternal recall is generally a valid measure for perinatal variables 10 years after pregnancy. However, caution should be taken regarding variables such as substance use, medical problems, birth length, and post-delivery complications.
本研究旨在评估双生子样本中，产后8至10年母亲回忆若干围产期变量的有效性。在南加州大学双生子研究的一组母亲中（N = 611），产后8至10年收集回顾性信息，并与病历进行比较以进行有效性分析。大多数变量的回忆显示出高度一致至完全一致（κ = 0.60 - 1.00），孕期特定医疗问题（κ ≤ 0.40）以及母亲提供连续数据时的物质使用情况（如每日吸烟量；r ≤ 0.24）明显例外。除分娩方式外，新生儿重症监护病房入院、出生体重、新生儿信息以及产后并发症的回忆准确性也较低。对于双胞胎母亲而言，产后10年母亲回忆通常是围产期变量的有效测量方法。然而，对于物质使用、医疗问题、出生身长和产后并发症等变量应谨慎对待。
