The National Institute of Mental Health (NIMH) addressed in its 2008 Strategic Plan an emerging concern that the current diagnostic system was hampering translational research, as accumulating data suggested that disorder categories constituted heterogeneous syndromes rather than specific diseases. However, established practices in peer review placed high priority on extant disorders in evaluating grant applications for mental illness. To provide guidelines for alternative study designs, NIMH included a goal to develop new ways of studying psychopathology based on dimensions of measurable behavior and related neurobiological measures. The Research Domain Criteria (RDoC) project is the result, intended to build a literature that informs new conceptions of mental illness and future revisions to diagnostic manuals. The framework calls for the study of empirically-derived fundamental dimensions as characterized by related behavioral/psychological and neurobiological data (e.g., reward valuation, working memory). RDoC also emphasizes full-range dimensional approaches (from typical to increasingly abnormal), neurodevelopment and environmental effects, and research designs that integrate data across behavioral, biological, and self-report measures. This commentary provides an overview of the project's first decade and its potential future directions. RDoC remains grounded in experimental psychopathology perspectives, and its progress is strongly linked to psychological measurement and integrative approaches to brain-behavior relationships.
美国国立精神卫生研究所(NIMH)在其2008年战略计划中提到了一个新出现的问题,即当前的诊断系统正在阻碍转化研究,因为越来越多的数据表明,疾病类别构成的是异质性综合征而非特定疾病。然而,同行评审的既定做法在评估精神疾病的资助申请时,高度重视现有的疾病。为了为替代研究设计提供指导方针,NIMH设定了一个目标,即基于可测量行为的维度和相关神经生物学测量方法,开发研究精神病理学的新方法。研究领域标准(RDoC)项目就是这样的成果,旨在构建一种文献,为精神疾病的新概念和诊断手册的未来修订提供信息。该框架要求研究由相关行为/心理和神经生物学数据所表征的实证衍生的基本维度(例如,奖励评估、工作记忆)。RDoC还强调全范围的维度方法(从典型到越来越异常)、神经发育和环境影响,以及整合行为、生物学和自我报告测量数据的研究设计。本评论概述了该项目的第一个十年及其潜在的未来方向。RDoC仍然基于实验精神病理学的观点,其进展与心理测量以及脑与行为关系的综合方法紧密相关。
