To estimate the difference in confidence to become active despite low back pain in people who were exposed to one of 2 video interventions delivered on social media, compared to no intervention. A proof-of-concept, 3-group randomized controlled trial, in a 1:1:1 ratio. Participants aged 18 years and over, with and without low back pain, were recruited via the social media channel Facebook, to view either a humorous video, a neutral video, or to no intervention. The videos were delivered online, explained evidence-based management for low back pain, and were designed to "go viral." The primary outcome was confidence in becoming active despite pain, measured using the Pain Self Efficacy Questionnaire (Item 10) (ranges from 0 [not at all confident] to 6 [completely confident]) immediately after watching the video. We aimed to capture the real-time impact and immediate reactions that contributed to the content's reach. Among 1933 randomized participants (mean [standard deviation] age: 58.9 [14.0] years, 1285 [75%] women), 1232 [70%] had low back pain and 88.8% completed the primary outcome. One thousand two hundred sixty-four participants were randomized to receive a video intervention, and 633 participants did not receive a video. On a 6-point scale, individuals exposed to either video (n = 1088) showed a mean confidence level 0.3 points higher (95% confidence interval: 0.1, 0.6) compared with no video (n = 630). Participants who viewed a brief video intervention reported a very small difference in confidence to become active despite low back pain, compared with no intervention. The difference may lack clinical relevance. .
评估在社交媒体上接触到 2 种视频干预中的 1 种（幽默视频或中性视频）与未接受干预相比，患有或不患有下背痛的人群对疼痛仍保持活跃的信心差异。这是一项概念验证、3 组随机对照试验，采用 1:1:1 的比例进行随机分组。参与者年龄在 18 岁及以上，有或没有下背痛，通过社交媒体渠道 Facebook 招募，观看幽默视频、中性视频或不观看视频。视频在线提供，解释了针对下背痛的循证管理，并旨在“传播开来”。主要结局是观看视频后即刻使用疼痛自我效能问卷（第 10 项）（范围从 0[一点也不自信]到 6[完全自信]）评估对疼痛仍保持活跃的信心。我们旨在捕捉对内容传播有贡献的实时影响和即时反应。在 1933 名随机参与者中（平均[标准差]年龄：58.9[14.0]岁，1285[75%]为女性），1232 名[70%]参与者患有下背痛，88.8%完成了主要结局。1264 名参与者被随机分配接受视频干预，633 名参与者未接受视频干预。在 6 分制中，接触视频的个体（n=1088）比未接受视频的个体（n=630）表现出 0.3 分更高的平均信心水平（95%置信区间：0.1，0.6）。与未接受干预相比，观看简短视频干预的参与者报告称对疼痛仍保持活跃的信心有很小差异。这种差异可能缺乏临床意义。
