This article responds to the argued lack of clearly articulated, consistent, and agreed criteria that might be used by researchers for determining the adequacy of a given concept for a given task. It does so by describing the development of a framework of such criteria, presenting that framework, and illustratively applying it to the evaluation of the concept of warm-up in psychodrama. The framework comprises eight criteria in three categories: the intrinsic qualities of a concept (the criteria of clarity, comprehensiveness, parsimony, and resonance), the contextualization of a concept (differentiation and connectedness), and its application (epistemic utility and practical utility). Using the framework to evaluate the concept of warm-up in the context of its use in psychodrama suggests its potential to make significant differentiations. It is argued that this framework may contribute to evaluating other concepts in other contexts, although the extent of such generalizability remains to be ascertained.
