The question of whether mental disorders are discrete clinical conditions or arbitrary distinctions along dimensions of functioning is a long-standing issue, but its importance is escalating with the growing recognition of the frustrations and limitations engendered by the categorical model. The authors provide an overview of some of the dilemmas of the categorical model, followed by a discussion of research that addresses whether mental disorders are accurately or optimally classified categorically or dimensionally. The authors' intention is to document the importance of this issue and to suggest that future editions of the Diagnostic and Statistical Manual of Mental Disorders give more recognition to dimensional models of classification. They conclude with a dimensional mental disorder classification that they suggest provides a useful model.
精神障碍是离散的临床病症还是沿着功能维度的任意区分，这一问题由来已久，但随着人们越来越认识到分类模型所带来的挫折和局限性，其重要性日益凸显。作者概述了分类模型的一些困境，随后讨论了关于精神障碍是按类别还是按维度进行准确或最优分类的研究。作者的目的是记录这一问题的重要性，并建议《精神障碍诊断与统计手册》未来版本更多地认可维度分类模型。他们最后给出了一个维度性精神障碍分类，认为这提供了一个有用的模型。
