The Louisville Twin Study (LTS) is nationally recognized as one of the largest and most comprehensive studies of child development related to multiple birth status. The LTS is unique because of the extensive longitudinal face-to-face assessments, the frequency of data collection, the inclusion of data on additional family members (i.e., parents, siblings, grandparents; and later, twins' own spouses and children), and the variety of data collection methods used. Data preservation efforts began in 2008 and are largely complete, although efforts are ongoing to obtain funding to convert the electronic data to a newer format. A pilot study was completed in the summer of 2018 to bring the twins, who are now middle-aged, back for testing. A grant is currently under review to extend the pilot study to include all former participants who are now ≥40 years of age. Opportunities for collaboration are welcome.
路易斯维尔双生子研究（LTS）在全国范围内被公认为是与多胞胎状况相关的最大规模、最全面的儿童发展研究之一。LTS独具特色，原因在于其广泛的纵向面对面评估、数据收集的频率、纳入了其他家庭成员（即父母、兄弟姐妹、祖父母；后来还包括双胞胎自己的配偶和子女）的数据，以及所使用的数据收集方法的多样性。数据保存工作始于2008年，目前已基本完成，不过仍在努力争取资金，以便将电子数据转换为更新的格式。2018年夏天完成了一项试点研究，让现已步入中年的双胞胎回来接受测试。目前正在审核一项拨款申请，以将试点研究扩展到所有年龄≥40岁的前参与者。欢迎合作机会。
