BACKGROUND
Safety measures should be applied to reduce work-related fatal and non-fatal fall injuries. However, according to the labor inspectorate, more than 80% of Dutch construction sites violate safety regulations for working from heights. To increase compliance with safety regulations, employers and workers have to select, implement and monitor safety measures. To facilitate this behavioral change, stimulating knowledge awareness and personalized feedback are frequently advocated behavior change techniques. For this study, two behavior change strategies have been developed in addition to the announcement of safety inspections by the labor inspectorate. These strategies consist of 1) face-to-face contacts with safety consultants and 2) direct mail with access to internet facilities. The objective of this study is to evaluate the effectiveness of these two strategies on the safety violations for working from heights, the process and the cost measures.
METHODS/DESIGN: This study is a block randomized intervention trial in 27 cities to establish the effects of the face-to-face guidance strategy (N = 9), a direct mailing strategy (N = 9) and a control condition of no guidance (N = 9) on safety violations to record by labor inspectors after three months. A process evaluation for both strategies will be performed to determine program implementation (reach, dose delivered and dose received), satisfaction, knowledge and perceived safety behavior. A cost analysis will be performed to establish the financial costs for both strategies. The present study is in accordance with the CONSORT statement.
DISCUSSION
This study increases insight into performing practice-based randomized controlled trials. The outcome will help to evaluate the effect of two guidance strategies on safety violations. If these strategies are effective, implementation of these strategies through the national institute of safety and health or labor inspectorate can take place to guide construction companies in complying with safety regulations.

背景
应采取安全措施以减少与工作相关的致命和非致命坠落伤害。然而，据劳动监察机构称，超过80%的荷兰建筑工地违反高空作业安全规定。为提高对安全规定的遵守程度，雇主和工人必须选择、实施并监督安全措施。为促进这种行为改变，激发知识意识和提供个性化反馈是经常倡导的行为改变技巧。在本研究中，除了劳动监察机构宣布的安全检查外，还制定了两种行为改变策略。这些策略包括：1）与安全顾问进行面对面接触；2）通过直接邮寄并提供互联网设施访问权限。本研究的目的是评估这两种策略在高空作业安全违规、过程和成本措施方面的有效性。
方法/设计：本研究是一项在27个城市进行的整群随机干预试验，以确定面对面指导策略（N = 9）、直接邮寄策略（N = 9）和无指导的对照条件（N = 9）对三个月后劳动监察员记录的安全违规行为的影响。将对两种策略进行过程评估，以确定项目实施情况（覆盖范围、提供的剂量和接受的剂量）、满意度、知识和感知安全行为。将进行成本分析以确定两种策略的财务成本。本研究符合CONSORT声明。
讨论
本研究增加了对进行基于实践的随机对照试验的认识。结果将有助于评估两种指导策略对安全违规行为的影响。如果这些策略有效，可以通过国家安全与健康研究所或劳动监察机构实施这些策略，以指导建筑公司遵守安全规定。
