The incorrect use of child car seats is common, with significant negative effects on crash protection for child passengers. There is currently little evidence for effective, practical countermeasures for incorrect use. The provision of clear and comprehensible materials on correct use supplied with restraints at the point of sale could be highly cost-effective and achieve similar benefits to restraint-fitting services or hands-on training; however, routinely supplied instructions in their current form are frequently difficult to understand. We are conducting a randomised controlled trial of the consumer-driven redesign of instructional materials, consisting of an instruction sheet, swing tags and online training videos. This paper presents the protocol that will be used in an innovate process evaluation that will use the primary outcome of overall serious misuse assessed at six months, together with a survey and semi-structured interviews to determine fidelity, dose and outcomes for all intervention participants. The study will assess intervention delivery and external factors that may impact the effectiveness of the intervention, including experience, health literacy, confidence and attitudes. When it has been conducted, this process evaluation will provide enhanced understanding of the mechanisms through which the intervention works or not, aspects of the implementation process key to success of the intervention and insight into how external factors influence the success of the intervention.
儿童汽车安全座椅的使用不当较为常见，这对乘车儿童的碰撞保护会产生严重的负面影响。目前，针对不当使用，几乎没有有效的、实用的对策。在销售点为约束装置提供关于正确使用的清晰易懂的材料可能具有很高的成本效益，并能实现与约束装置适配服务或实践培训类似的效益；然而，目前以这种形式提供的常规说明通常难以理解。我们正在进行一项消费者驱动的指导材料重新设计的随机对照试验，包括使用说明、吊牌和在线培训视频。本文介绍了将在创新的过程评估中使用的方案，该评估将使用六个月时总体严重误用的主要结果，以及调查和半结构化访谈，以确定所有干预参与者的保真度、剂量和结果。该研究将评估干预措施的提供情况和可能影响干预效果的外部因素，包括经验、健康素养、信心和态度。完成后，该过程评估将更深入地了解干预措施的作用机制或失效原因、对干预措施成功至关重要的实施过程方面，以及外部因素如何影响干预措施的成功。
