摘要传统的DSM和ICD诊断标准难以体现精神障碍的复杂性，包括症状的连续谱和异质性等。近些年以研究领域标准（research domain criteria，RDoC）框架为基础的跨诊断模式适用于儿童青少年精神障碍的临床研究，用以深入理解疾病的病理机制、预防疾病的发生发展、制订跨诊断治疗方法。

abstractsTraditional diagnostic criteria such as the DSM and ICD have limitations in capturing the complexity of mental disorders, including the spectrum and heterogeneity of symptoms. In recent years, the transdiagnostic model based on the Research Domain Criteria (RDoC) framework has been increasingly applied to clinical research on child and adolescent mental disorders. This model facilitates a deeper understanding of the underlying pathological mechanism, supports the prevention of disease onset and progression, and informs the development of transdiagnostic treatment approaches.
