Young workers in many industrialized countries experience a higher rate of largely preventable occupation-related injuries compared with adults. Safety education and training are considered critical to the prevention of these incidents. This can be promoted by the dissemination and scale-out of an evidence-based, safety training programs in vocational education. The aim of this study was to identify the intervention core components that comprise the "active ingredients" of a safety training intervention for young workers and assess the impact on student outcomes of interest. Fidelity of implementation was operationalized using measures of adherence and quality of intervention delivery. For this study, data were collected through a school-based, cluster randomized trial conducted in 2015 in eight Finnish upper secondary-level vocational schools (n = 229 students in 22 groups, each with one teacher). Results indicate that the intervention core components (safety skills training, safety inoculation training, a positive atmosphere for safety learning, and active learning techniques) had differing associations with student outcomes. Adherence related to the acquisition of safety skills training was the strongest active ingredient in terms of positive effects. Furthermore, quality of delivery in terms of fostering positive learning atmosphere and utilizing active learning methods was associated especially with motivational outcomes. These findings indicate that different active ingredients complemented each other. Contrary to expectations, we found no statistically significant relationship between any of the core components and risk-taking attitudes. The current study advances prevention science by identifying the active ingredients of an evidence-based intervention, implemented in Finnish vocational school settings, that helps protect young workers from work-related morbidity and mortality.
与成年人相比，许多工业化国家的年轻工人在很大程度上更容易遭受可预防的与工作相关的伤害。安全教育和培训被认为是预防这些事件的关键。这可以通过在职业教育中传播和推广基于证据的安全培训计划来实现。本研究的目的是确定干预的核心组成部分，这些组成部分构成了针对年轻工人的安全培训干预措施的“有效成分”，并评估其对学生关注结果的影响。实施的保真度是使用遵守和干预提供质量的措施来操作的。在这项研究中，数据是通过 2015 年在芬兰八所中等职业学校（n=229 名学生，22 组，每组一名教师）进行的基于学校的集群随机试验收集的。结果表明，干预的核心组成部分（安全技能培训、安全接种培训、安全学习的积极氛围和主动学习技巧）与学生的结果有不同的关联。就获得安全技能培训而言，与坚持相关的是积极影响的最强有力的有效成分。此外，在培养积极学习氛围和利用主动学习方法方面的交付质量尤其与激励性结果相关。这些发现表明，不同的有效成分相辅相成。出乎意料的是，我们没有发现任何核心组成部分与冒险态度之间存在统计学上显著的关系。本研究通过确定在芬兰职业学校环境中实施的基于证据的干预措施的有效成分，为预防科学提供了新的认识，有助于保护年轻工人免受与工作相关的发病率和死亡率的影响。
