Social media provide promising contemporary platforms for sharing public health information with a broad audience. Before implementation, testing social media campaigns that are intended to engage audiences and initiate behaviour change is necessary. This trial aims to investigate the effectiveness of a public health campaign to increase people's confidence in becoming more active despite low back pain in comparison with no intervention.
This is an online randomised controlled trial with two intervention groups and one control group in a 1:1:1 allocation. People over 18 years of age and fluent in English will be recruited via social media advertising. We developed a social media-based public health campaign to support recommendations for managing low back pain. The interventions are two videos. Participants in the control group will be asked questions about low back pain but will not view either video intervention. The primary outcome will be item 10 of the Pain Self-Efficacy Questionnaire, which asks participants to rate how confident they would feel to gradually become more active despite pain ranging from 0 (not at all confident) to 6 (completely confident). This outcome will be measured immediately in all participant groups. We will compare group mean of the three arms of the trial using univariate analyses of variance.
This trial has been prospectively registered with the Australian New Zealand Clinical Trials Registry. We obtained ethical approval from our institutions Human Research Ethics Committee before data collection. We will publish the results in a peer-reviewed medical journal and on institution websites.

社交媒体为向广大受众分享公共卫生信息提供了有前景的现代平台。在实施之前，有必要对旨在吸引受众并引发行为改变的社交媒体活动进行测试。本试验旨在研究一项公共卫生运动的效果，即在没有干预的情况下，与不干预相比，该运动旨在增强人们对腰痛时更积极活动的信心。
这是一项在线随机对照试验，采用 1:1:1 分配，将 18 岁以上、英语流利的人群分为两组干预组和一组对照组。通过社交媒体广告招募参与者。我们开发了一种基于社交媒体的公共卫生运动，以支持管理腰痛的建议。干预措施是两个视频。对照组的参与者将被问及腰痛问题，但不会观看任何视频干预。主要结果将是疼痛自我效能问卷的第 10 项，要求参与者对自己在疼痛下逐渐变得更加活跃的信心进行评分，范围从 0（一点也不自信）到 6（完全自信）。所有参与者组将立即测量这一结果。我们将使用单变量方差分析比较试验的三个臂的组平均值。
本试验已在澳大利亚和新西兰临床试验注册中心进行了前瞻性注册。在数据收集之前，我们从机构人类研究伦理委员会获得了伦理批准。我们将在同行评议的医学期刊和机构网站上发表研究结果。
