NKI-sample

The enhanced Nathan Kline Institute-Rockland Sample (NKI-RS) is an ongoing, institutionally centered endeavor aimed at creating a large-scale (N > 1000) community sample of participants across the lifespan. Measures include a wide array of physiological and psychological assessments, genetic information, and advanced neuroimaging. Anonymized data will be publicly shared openly and prospectively (i.e., on a quarterly basis).

The National Institute of Mental Health strategic plan for advancing psychiatric neuroscience calls for increased discovery science initiatives in an effort to deliniate developmental trajectories for risk and resilience across the lifespan. Such initiatives require large, openly accessible datasets that contain sufficient detail to enable the generation and testing of multiple hypotheses. The NKI-RS is intended to help meet this need.

For this release, the participant age in the participants.tsv file is the age at enrollment, while individual session TSVs contain the age of the participant when the session data was acquired and the number of minutes elapsed since the date of enrollment.

增强版内森·克莱因研究所-罗克兰样本（Nathan Kline Institute-Rockland Sample, NKI-RS）是一项持续开展、以机构为核心的研究项目，旨在构建覆盖全生命周期、样本量超1000名参与者的大型社区样本队列。该样本涵盖多类生理与心理评估、遗传信息及先进神经影像学数据。匿名化数据将以公开且前瞻性的方式共享，即按季度定期发布。

美国国家精神卫生研究所（National Institute of Mental Health）推进精神神经科学的战略规划，呼吁加大发现科学举措力度，以阐明全生命周期内精神疾病风险与复原力的发展轨迹。此类举措亟需规模可观、公开可获取且具备足够细节的数据集，以支撑多项假说的生成与验证。NKI-RS正是为满足这一需求而打造的项目。

在本次发布的数据中，participants.tsv文件内记录的参与者年龄为入组时年龄；而各独立会话的TSV文件则包含会话数据采集时的参与者年龄，以及自入组日期起流逝的分钟数。
