The Netherlands Twin Register (NTR) consists of individuals who have agreed to participate in twin-family studies and was established and is managed by the Department of Biological Psychology, VU University Amsterdam (see: https://tweelingenregister.vu.nl/). The NTR was established in 1987 and has enrolled around 120.000 twins and a roughly equal number of their relatives. The majority of twin families have participated one or more times in survey studies on a host of epidemiological variables including social demography, personality, lifestyle, somatic and mental health, and subsamples took part in biomaterial collection (e.g. DNA) and dedicated projects for e.g. neuropsychological, biomarker, and behavioral traits. The recruitment into the NTR is fully inclusive without any restrictions on enrolment. The NTR is committed to actively seek the commitment of its participants to science and their continued involvement in NTR research by maintaining a website, electronic newsletters, and the MijnNTR portal that provides personalized feedback to participants. The NTR resources, e.g. the longitudinal phenotyping, the extended pedigree structures, and the multi-generation genotyping allow for future twin-family research that will contribute to gene discovery, causality modelling, and studies of genetic and cultural inheritance of behavioral traits and mental and physical health. In the CID data catalogue, only the NTR projects for children and adolescents (<18 years of age) have been included. This is refered to as the Young Netherlands Twin Register (YNTR).荷兰双生子登记库（Netherlands Twin Register，简称NTR）由阿姆斯特丹自由大学生物心理学系建立并管理，收录了所有同意参与双生子家庭研究的受试个体（详见：https://tweelingenregister.vu.nl/）。NTR始建于1987年，目前已登记约12万名双生子，以及数量相当的亲属群体。多数双生子家庭已参与过一次或多次流行病学调查研究，调查内容涵盖社会人口学特征、人格特质、生活方式、躯体与心理健康等多类变量；部分子样本还参与了生物样本采集（如脱氧核糖核酸DNA），以及针对神经心理学指标、生物标志物与行为特征的专项研究项目。NTR的招募流程完全开放，无任何入组限制。该库致力于通过维护官方网站、电子通讯刊物，以及为受试者提供个性化反馈的MijnNTR门户平台，积极激发受试者参与科学研究的热忱，并维持其对NTR研究的持续参与。NTR的各类研究资源，例如纵向表型分型、扩展家系结构与多代基因分型技术，可为未来双生子家庭研究提供支撑，助力基因发现、因果关系建模，以及行为特征与身心健康的遗传与文化继承相关研究。在CID数据目录中，仅收录了针对儿童与青少年（年龄<18岁）的NTR研究项目，该子库被称为青年荷兰双生子登记库（Young Netherlands Twin Register，简称YNTR）。
