目的导向试验设计（PGTD）是一种新的启发式框架，用于规划健康相关行为干预的随机对照试验。其使用有助于确保研究设计和对照组或比较组与试验的主要目的相一致。当与最近开发的用于健康相关行为试验中比较物选择的实用模型结合使用时（Freedland等人，2019），PGTD框架可以帮助解决行为随机对照试验中使用的比较器的不确定性，分歧和争议。例如，PGTD可以帮助回答有关行为试验中是否、何时以及如何控制注意力的问题。PGTD框架可用于评估已发表的试验，但主要用作行为试验计划工具。
Purpose-guided trial design (PGTD) is a novel heuristic framework for planning randomized controlled trials of health-related behavioral interventions. Its use helps to ensure that the study design and the control or comparison group are compatible with the primary purpose of the trial. When used in conjunction with the recently developed pragmatic model for comparator selection in health-related behavioral trials (Freedland et al., 2019), the PGTD framework can help to resolve uncertainties, disagreements, and controversies about the comparators that are used in behavioral randomized controlled trials. For example, PGTD can help to answer questions about whether, when, and how to control for attention in behavioral trials. The PGTD framework can be used to evaluate published trials, but it is primarily intended for use as a behavioral trial planning tool.
