Insight into stage transition determinants is necessary to develop and evaluate stage-tailored health-promoting interventions. A three-round Delphi study among stages of change researchers was conducted to make an inventory of opinions and examine agreement on determinants of forward transitions between Transtheoretical stages of change. In the first round, 10 experts completed an electronic questionnaire with open-ended questions about potential determinants for each stage transition. In the second round, a structured electronic questionnaire based on the first round results was sent to authors of scientific papers on stages of change, published between 1995 and May 2002. In the third round, participants were presented feedback about the second round and were asked to re-rate their answers based on the information provided. Results showed that participants agreed on various transition determinants, but that determinants were not always stage-specific, e.g. control-related issues and social support were identified as determinants of all transitions from contemplation to maintenance. The results further showed lower consensus about determinants of earlier stage transitions than about determinants of later stage transitions. The Delphi study identified hypotheses worthy of further examination in longitudinal observational and experimental studies.
深入了解阶段转变的决定因素对于制定和评估针对特定阶段的健康促进干预措施至关重要。我们对处于行为改变阶段的研究人员进行了三轮德尔菲研究，以梳理意见并检验关于跨理论行为改变阶段之间向前转变的决定因素的共识。在第一轮中，10位专家完成了一份电子问卷，其中包含关于每个阶段转变潜在决定因素的开放式问题。在第二轮中，一份基于第一轮结果的结构化电子问卷被发送给1995年至2002年5月期间发表的关于行为改变阶段的科学论文的作者。在第三轮中，向参与者反馈了第二轮的情况，并要求他们根据所提供的信息重新评估自己的答案。结果表明，参与者在各种转变决定因素上达成了一致，但这些决定因素并不总是特定于某个阶段，例如与控制相关的问题和社会支持被确定为从沉思到维持的所有转变的决定因素。结果还表明，与后期阶段转变的决定因素相比，早期阶段转变的决定因素的共识较低。德尔菲研究确定了一些假设，值得在纵向观察性研究和实验性研究中进一步检验。
