There is increasing interest in brief and very brief behaviour change interventions for physical activity as they are potentially scalable to the population level. However, few very brief interventions (VBIs) have been published, and evidence is lacking about their feasibility, acceptability and which 'active ingredients' (behaviour change techniques) would maximise their effectiveness. The aim of this research was to identify and develop promising VBIs for physical activity and test their feasibility and acceptability in the context of preventive health checks in primary care.
The process included two stages, guided by four criteria: effectiveness, feasibility, acceptability, and cost. In Stage 1, we used an iterative approach informed by systematic reviews, a scoping review of BCTs, team discussion, stakeholder consultation, a qualitative study, and cost estimation to guide the development of promising VBIs. In Stage 2, a feasibility study assessed the feasibility and acceptability of the short-listed VBIs, using tape-recordings and interviews with practitioners (n = 4) and patients (n = 68), to decide which VBIs merited further evaluation in a pilot trial.
Four VBIs were short-listed: Motivational intervention; Action Planning intervention; Pedometer intervention; and Physical Activity Diary intervention. All were deliverable in around five minutes and were feasible and acceptable to participants and practitioners. Based on the results of interviews with practitioners and patients, techniques from the VBIs were combined into three new VBIs for further evaluation in a pilot trial.
Using a two-stage approach, in which we considered the practicability of VBIs (acceptability, feasibility and cost) alongside potential efficacy from the outset, we developed a short-list of four promising VBIs for physical activity and demonstrated that they were acceptable and feasible as part of a preventive health check in primary care.

针对身体活动的简短及超简短行为改变干预措施正受到越来越多的关注，因为它们有可能扩大到人群层面。然而，很少有超简短干预措施（VBIs）被发表，并且缺乏关于其可行性、可接受性以及哪些“有效成分”（行为改变技术）能使其效果最大化的证据。本研究的目的是识别并开发有前景的身体活动VBIs，并在初级保健中的预防性健康检查背景下测试其可行性和可接受性。
该过程包括两个阶段，由四个标准指导：有效性、可行性、可接受性和成本。在第一阶段，我们采用了一种迭代方法，该方法基于系统评价、行为改变技术的范围综述、团队讨论、利益相关者咨询、定性研究和成本估算，以指导有前景的VBIs的开发。在第二阶段，一项可行性研究通过对从业者（n = 4）和患者（n = 68）进行录音和访谈，评估了入围VBIs的可行性和可接受性，以确定哪些VBIs值得在试点试验中进一步评估。
四个VBIs入围：动机干预；行动计划干预；计步器干预；以及身体活动日记干预。所有这些干预都可在大约五分钟内完成，并且对参与者和从业者来说是可行且可接受的。根据对从业者和患者的访谈结果，将VBIs中的技术组合成三个新的VBIs，以便在试点试验中进行进一步评估。
通过采用两阶段方法，从一开始我们就考虑了VBIs的实用性（可接受性、可行性和成本）以及潜在疗效，我们制定了一份包含四个有前景的身体活动VBIs的入围名单，并证明它们作为初级保健中预防性健康检查的一部分是可接受且可行的。
