The Working Group undertook a critical, comprehensive synthesis of the response shift work to date. We aimed to (1) describe the rationale for this initiative; (2) outline how the Working Group operated; (3) summarize the papers that comprise this initiative; and (4) discuss the way forward.
Four interdisciplinary teams, consisting of response shift experts, external experts, and new investigators, prepared papers on (1) definitions and theoretical underpinnings, (2) operationalizations and response shift methods, (3) implications for healthcare decision-making, and (4) on the published magnitudes of response shift effects. Draft documents were discussed during a two-day meeting. Papers were reviewed by all members.
Vanier and colleagues revised the formal definition and theory of response shift, and applied these in an amended, explanatory model of response shift. Sébille and colleagues conducted a critical examination of eleven response shift methods and concluded that for each method extra steps are required to make the response shift interpretation plausible. Sawatzky and colleagues created a framework for considering the impact of response shift on healthcare decision-making at the level of the individual patient (micro), the organization (meso), and policy (macro). Sajobi and colleagues are conducting a meta-analysis of published response shift effects. Preliminary findings indicate that the mean effect sizes are often small and variable across studies that measure different outcomes and use different methods.
Future response shift research will benefit from collaboration among diverse people, formulating alternative hypotheses of response shift, and conducting the most conclusive studies aimed at testing these (falsification).
工作组对迄今为止的反应转移工作进行了批判性、全面的综合分析。我们旨在：(1)描述开展此项工作的基本原理；(2)概述工作组的运作方式；(3)总结本项工作所包含的论文；(4)讨论未来的发展方向。
四个跨学科团队，由反应转移专家、外部专家和新调查员组成，分别准备了关于(1)定义和理论基础、(2)操作化和反应转移方法、(3)对医疗保健决策的影响以及(4)发表的反应转移效应幅度的论文。在为期两天的会议上讨论了草案文件。所有成员都对论文进行了审查。
Vanier 及其同事修订了反应转移的正式定义和理论，并将其应用于修订后的反应转移解释模型中。Sébille 及其同事对十一种反应转移方法进行了批判性审查，得出的结论是，对于每种方法，都需要额外的步骤才能使反应转移解释变得合理。Sawatzky 及其同事为考虑反应转移对个体患者(微观)、组织(中观)和政策(宏观)层面医疗保健决策的影响创建了一个框架。Sajobi 及其同事正在对已发表的反应转移效应进行荟萃分析。初步研究结果表明，在测量不同结果和使用不同方法的研究中，效应大小的平均值通常较小且变化较大。
未来的反应转移研究将受益于不同人群之间的合作，提出反应转移的替代假设，并进行最具结论性的研究，旨在检验这些假设(证伪)。
