Characterization and Treatment of Adolescent Depression (CAT-D)

# NIMH CAT-D This dataset is a portion of National Institute of Mental Health Characterization and Treatment of Adolescent Depression (NIMH CAT-D) study's data. This preliminary release includes multi-echo resting state data from 190 sessions across 43 participants. The NIMH CAT-D study includes healthy volunteers (HVs) and adolescents with depression. Individuals with depression were scanned every 4 months and HVs were scanned yearly. Some of the depressed participants were enrolled in in-patient or out-patient treatment for a period of the longitudinal study. Please see [Sadeghi et al., 2022](https://doi.org/10.1016/j.jaac.2022.04.004). The full behavioral data from this study is available on [github](https://github.com/transatlantic-comppsych/CATD-study); this repository only includes behavioral data associated with a scanning session. ## Session numbers Session numbers indicate the study visit with v1-v4 representing the first year of longitudinal scans for depressed participants. Healthy participants only have v1 and v4 scans for their first year. During outpatient treatment, scan sessions are referred to as o1, o4, o8, and o12. During inpatient treatment, participants were scanned approximately weekly, the sessions are referred to as iX were X is the week of their inpatient stay. Some scanning session do double duty as both a regular longitudinal visit and outpatient or inpatient visits. These sessions are given both labels, i.e. v4o1 or v2i14.# NIMH CAT-D 数据集 本数据集源自美国国立精神卫生研究所青少年抑郁症表征与治疗研究（National Institute of Mental Health Characterization and Treatment of Adolescent Depression，简称NIMH CAT-D）。本次初步发布的数据集涵盖43名受试者的190次扫描时段的多回波静息态数据。该研究的受试群体包含健康志愿者（Healthy Volunteers, HVs）与抑郁症青少年：抑郁症患者每4个月接受一次扫描，健康志愿者则每年完成一次扫描。部分抑郁症受试者在本纵向研究周期内，曾阶段性参与住院或门诊治疗。详细研究背景可参阅[Sadeghi等人，2022](https://doi.org/10.1016/j.jaac.2022.04.004)。本研究的完整行为数据集已上传至[GitHub](https://github.com/transatlantic-comppsych/CATD-study)，当前仓库仅收录与单次扫描时段相关的行为数据。 ## 扫描时段编号说明 扫描时段编号用于标识研究访视流程：其中v1至v4代表抑郁症受试者纵向随访第一年的四次扫描。健康志愿者仅需在随访第一年完成v1与v4两次扫描。门诊治疗期间的扫描时段编号为o1、o4、o8及o12。住院治疗期间，受试者约每周接受一次扫描，时段编号以iX标识，其中X为受试者的住院周次。部分扫描时段兼具常规纵向访视与门诊/住院访视的双重属性，因此会同时标注两种编号，例如v4o1或v2i14。

背景与挑战

背景概述

该数据集是美国国家心理健康研究所（NIMH）的青少年抑郁症特征与治疗（CAT-D）研究的一部分，专注于青少年抑郁症的神经影像学研究。数据集包含190次会话的多回波静息态功能磁共振成像数据，涉及43名参与者（包括健康志愿者和抑郁症青少年），采用纵向设计以追踪抑郁症的进展和治疗效果。数据集还提供了任务相关数据（如Monetary Incentive Delay任务），旨在支持青少年抑郁症的病理机制和干预研究。
