This article examines constructs, propositions, and assumptions of the extended parallel process model (EPPM). Review of the EPPM literature reveals that its theoretical concepts are thoroughly developed, but the theory lacks consistency in operational definitions of some of its constructs. Out of the 12 propositions of the EPPM, a few have not been tested explicitly and not a single one received unequivocal empirical support. This article proposes alternative operationalization for some of the constructs and examines some assumptions of this theory, such as additive relationship between the constructs, the role of time and issue of thresholds, and disregard for the existing state of the audience. Finally, the role of the EPPM as a potential foundation for a general theory of negative emotional appeals is addressed.
本文考察了扩展平行过程模型（EPPM）的建构、命题和假设。对 EPPM 文献的回顾表明，其理论概念得到了深入发展，但该理论在一些建构的操作定义上缺乏一致性。在 EPPM 的 12 个命题中，有几个没有被明确测试，也没有一个得到明确的经验支持。本文提出了一些建构的替代操作化方法，并检验了该理论的一些假设，如建构之间的加性关系、时间和阈值问题的作用，以及对受众现有状态的忽视。最后，探讨了 EPPM 作为负面情感诉求一般理论的潜在基础的作用。
