Placebo effects have increasingly aroused scientific and public interest for their clinical and research values. However, underlying mechanisms of this mind–body phenomenon are not yet fully understood. In this article, I propose a new model according to which context-based placebo effects source from positive treatment beliefs but are directly caused by benefit expectations. By virtue of mediating belief-expectation transformation, placebo administration triggers, and thus has a pivotal role in, subsequent therapeutic responses.

安慰剂作用：一种新理论

安慰剂效应的临床和研究价值越来越引起科学和公众的关注。但是，这种身心现象的潜在机制尚未完全被理解。在本文中，我提出了一个新模型，根据该模型，基于上下文的安慰剂效应源自积极的治疗信念，但直接由受益预期引起。通过介导信念-预期转化，安慰剂给药触发随后的治疗反应，并因此在随后的治疗反应中起关键作用。
