Sedentary behaviour is defined as any waking behaviour characterised by low energy expenditure ≤1.5 metabolic equivalents while in a sitting, lying or reclining posture. The expanding evidence base suggests that sedentary behaviour may have a detrimental effect on health, well-being and is associated with an increased risk of all-cause mortality. We aim to review process evaluations of randomised controlled trials (RCTs) which included a measure of sedentary behaviour in adults in order to develop an understanding of intervention content, mechanisms of impact, implementation and delivery approaches and contexts, in which interventions were reported to be effective or effective. A secondary aim is to summarise participants, family and staff experiences of such interventions.
Ten electronic databases and reference lists from previous similar reviews will be searched. Eligible studies will be process evaluations of RCTs that measure sedentary behaviour as a primary or secondary outcome in adults. As this review will contribute to a programme to develop a community-based intervention to reduce sedentary behaviour in stroke survivors, interventions delivered in schools, colleges, universities or workplaces will be excluded. Two reviewers will perform study selection, data extraction and quality assessment. Disagreements between reviewers will be resolved by a third reviewer. Process evaluation data to be extracted include the aims and methods used in the process evaluation; implementation data; mechanisms of impact; contextual factors; participant, family and staff experiences of the interventions. A narrative approach will be used to synthesise and report qualitative and quantitative data. Reporting of the review will be informed by Preferred Reporting Items for Systematic Review and Meta-Analysis guidance.
Ethical approval is not required as it is a protocol for a systematic review. Findings will be disseminated through peer-reviewed publications and conference presentations.

久坐行为是指任何清醒状态下的行为，其特点是能量消耗低≤1.5 个代谢当量，同时处于坐姿、躺姿或斜倚姿势。不断扩大的证据基础表明，久坐行为可能对健康和幸福感产生不利影响，并且与全因死亡率增加相关。我们旨在综述包括成年人久坐行为测量的随机对照试验（RCT）的过程评估，以便了解干预内容、影响机制、实施和交付方法以及报告干预有效或有效的背景。次要目标是总结参与者、家庭和工作人员对这些干预措施的体验。
将检索 10 个电子数据库和以前类似综述的参考文献列表。合格的研究将是测量成年人久坐行为作为主要或次要结果的 RCT 的过程评估。由于本综述将有助于开发一项针对中风幸存者减少久坐行为的基于社区的干预计划，因此将排除在学校、学院、大学或工作场所进行的干预措施。两名评审员将进行研究选择、数据提取和质量评估。评审员之间的分歧将由第三名评审员解决。要提取的过程评估数据包括过程评估中使用的目的和方法；实施数据；影响机制；背景因素；参与者、家庭和工作人员对干预措施的体验。将使用叙述方法综合和报告定性和定量数据。综述报告将遵循系统评价和荟萃分析指南的建议。
由于这是系统综述的方案，因此不需要伦理批准。研究结果将通过同行评审的出版物和会议演示进行传播。
