使用自然语言来表达行为改变理论导致缺乏清晰度和一致性，阻碍了比较、整合、发展和使用。本文描述了一种用于表示行为改变理论的形式化系统的开发，旨在提高清晰度和一致性。一个给定的理论是用(1)它的组成构念（例如，“自我效能”、“感知威胁”或“主观规范”）来表示的，这些构念是被标记和定义的，(2)构念对之间的关系，可能是因果的、结构的或语义的。这种形式主义似乎足以代表五种常用的理论（健康信念模型、信息-动机-行为技能模型、社会认知理论、计划行为理论和跨理论模型）。理论作者和专家判断，该系统能够捕捉理论的主要命题。在概念验证之后，下一步是评估该系统在多大程度上可以应用于其他行为改变理论。
Use of natural language to represent behaviour-change theories has resulted in lack of clarity and consistency, hindering comparison, integration, development and use. This paper describes development of a formal system for representing behaviour-change theories that aims to improve clarity and consistency. A given theory is represented in terms of (1) its component constructs (for example, 'self-efficacy', 'perceived threat' or 'subjective norm'), which are labelled and defined, and (2) relationships between pairs of constructs, which may be causal, structural or semantic. This formalism appears adequate to represent five commonly used theories (health belief model, information-motivation-behavioural skill model, social cognitive theory, theory of planned behaviour and the trans-theoretical model). Theory authors and experts judged that the system was able to capture the main propositions of the theories. Following this proof of concept, the next step is to assess how far the system can be applied to other theories of behaviour change.
