Mental disorders are arguably one of the most complex and serious problems facing health practitioners today and yet their causes remain, largely, a mystery. Accordingly, there is frequent and heated debate over which of the many available models of mental disorder and their associated therapeutic interventions are likely to be most useful. The prevailing attitude toward the conceptualization of mental distress appears to be that a single superior model will emerge that neatly accounts for one or more disorder presentations: the “One Best Model” (OBM) perspective. In this article, we argue for a transition away from the OBM perspective toward a multiple model approach to psychopathology that is collaborative and pluralistic. We begin by outlining the particulars of the OBM perspective and elaborating on the problems it presents for psychopathology theory and practice. We then suggest specific ways in which this problem may be ameliorated, by adjusting how we approach the processes of modelling disorder, translating models into interventions, and applying models and interventions in practice.

精神疾病可以说是当今医务人员面临的最复杂，最严重的问题之一，但其原因在很大程度上仍是个谜。因此，关于许多可用的精神障碍模型及其相关的治疗干预方法中，哪一种最有用可能是一个经常而激烈的争论。对精神困扰概念化的普遍态度似乎是，将出现一个单一的高级模型，该模型巧妙地解释了一种或多种疾病的表现：“最佳模型”（OBM）观点。在本文中，我们主张从OBM观点过渡到协作和多元化的精神病理学多模型方法。我们首先概述OBM观点的细节，并详细阐述它对心理病理学理论和实践提出的问题。然后，我们通过调整我们处理建模障碍过程的方式，将模型转换为干预措施以及在实践中应用模型和干预措施的方式，提出解决此问题的具体方法。
