Immigrant day laborers suffer from disproportionate occupational health risks from hazardous reconstruction jobs after natural disasters. We conducted a randomized controlled trial of a short-video educational intervention to improve safety knowledge and intent to engage in safety preventive behaviors among 98 Hispanic day laborers (49 randomized to video and 49 control). The short video featured a male and a female who narrated 3 stories of day laborers who were injured while doing construction work in post-Katrina New Orleans. The main outcome measures were changes in scores for day laborer-reported safety knowledge and safety behaviors derived from interviewer-delivered baseline and post-intervention surveys. Video participants reported improvement in overall average safety knowledge score (mean score of 11.3 out of a max score of 12 or 94% when standardized to 0-100% scale), as compared to the control group (mean score of 8.6 or 72%) who were not offered the video ( < 0.00001). The intervention was highly successful in workers stating that they learned and were willing to change their safety preventive behaviors to reduce their occupational risk. The average safety behavior score was higher among those watching the video (17.2 out of a max of 22 or 78.1% when standardized on a scale 0-100%) as compared to control (14.5 or 65.9%) ( = 0.0024). A short video intervention can improve knowledge and intent to engage in preventive behaviors among Hispanic workers for which there is a dearth of construction safety preventive research.
移民日工在自然灾害后的危险重建工作中面临不成比例的职业健康风险。我们对一项短视频教育干预进行了随机对照试验,以提高 98 名西班牙裔日工的安全知识和参与安全预防行为的意愿(49 名随机分配到视频组,49 名分配到对照组)。短视频的特点是一男一女讲述了 3 个故事,讲述了在卡特里娜飓风后的新奥尔良从事建筑工作时受伤的日工。主要结果测量指标是通过采访者进行的基线和干预后调查得出的日工报告的安全知识和安全行为得分的变化。与未观看视频的对照组(平均得分为 8.6 或 72%)相比,观看视频的参与者报告总体平均安全知识得分有所提高(最高得分为 12 分,标准化后得分为 0-100%,平均得分为 11.3 或 94%)(<0.00001)。与对照组(标准化后得分为 0-100%,平均得分为 14.5 或 65.9%)相比,干预组中表示他们学习并愿意改变安全预防行为以降低职业风险的工人的平均安全行为得分更高(最高得分为 22 分,平均得分为 17.2 或 78.1%)(=0.0024)。短视频干预可以提高西班牙裔工人的知识和参与预防行为的意愿,而针对建筑安全预防的研究很少。
