Leading causes of unintentional child injury such as poisoning and falls are preventable, and the majority occur in the home. Numerous home safety interventions have been developed and tested to increase safety behaviors; however, no smart phone-based applications (apps) have been developed and evaluated for this purpose. The objective of this study was to evaluate whether a mobile technology-based health behavior change intervention, the Make Safe Happen® app, was an effective tool to increase safety knowledge and safety actions/behaviors for the prevention of child unintentional injuries in and around the home.
Data were collected in pretest and posttest online surveys from an existing nationwide population-based survey panel. Intervention subjects were randomized to organically (participant-driven) use the Make Safe Happen® app for 1 week, which provided home safety information and the ability to purchase safety products, while control participants were assigned to download and use an app about a topic other than home safety. The primary outcomes of safety knowledge and home safety actions were assessed by using linear mixed model regressions with intention-to-treat analyses.
A total of 5032 participants were randomized to either the intervention (n = 4182) or control (n = 850) group, with 2055 intervention participants downloading and entering their participant IDs into the Make Safe Happen® app. The online posttest survey was completed by 770 intervention and 283 control subjects. Mean knowledge parent safety score increased at a greater rate for intervention than control subjects (p < 0.0001), and at posttest was significantly higher for intervention than control subjects (p < 0.0001). The percentage of intervention subjects who reported doing all one-time and repeated safety actions significantly increased from pretest to posttest (p < 0.0001 and p = 0.0001, respectively), but there was no change among the control subjects (p = 0.1041 and p = 0.9755, respectively). At posttest, this percentage was larger for intervention than control subjects only for repeated safety actions (p = 0.0340).
The mobile application significantly improved safety knowledge and safety actions for participants using the Make Safe Happen® app, although loss to follow-up was a limitation. The results of this study indicate the usefulness of widespread distribution and use of the Make Safe Happen® app. Trial registration number NCT02751203 ; Registered April 26, 2016.
意外儿童伤害的主要原因，如中毒和跌倒，是可以预防的，且大多数发生在家中。为了增加安全行为，已经开发并测试了许多家庭安全干预措施；然而，尚未开发和评估用于此目的的基于智能手机的应用程序（应用）。本研究的目的是评估一种基于移动技术的健康行为改变干预措施——“让安全发生”应用程序，是否是一种有效的工具，可增加预防家庭内外儿童意外伤害的安全知识和安全行动/行为。
从现有的全国性基于人群的调查小组中，通过在线预测试和后测试收集数据。干预组受试者被随机分配以自主（参与者驱动）使用“让安全发生”应用程序1周，该应用程序提供家庭安全信息并具备购买安全产品的功能，而对照组参与者被分配下载并使用一个关于家庭安全以外主题的应用程序。通过使用意向性分析的线性混合模型回归来评估安全知识和家庭安全行动的主要结果。
共有5032名参与者被随机分配到干预组（n = 4182）或对照组（n = 850），其中2055名干预组参与者下载了“让安全发生”应用程序并输入了他们的参与者ID。770名干预组和283名对照组受试者完成了在线后测试调查。干预组受试者的平均知识家长安全得分比对照组受试者增加得更快（p < 0.0001），且在后测试时干预组受试者的得分显著高于对照组受试者（p < 0.0001）。报告进行了所有一次性和重复安全行动的干预组受试者的百分比从预测试到后测试显著增加（分别为p < 0.0001和p = 0.0001），但对照组受试者没有变化（分别为p = 0.1041和p = 0.9755）。在后测试时仅对于重复安全行动，干预组受试者的这一百分比大于对照组受试者（p = 0.0340）。
尽管失访是一个局限性，但移动应用程序显著提高了使用“让安全发生”应用程序的参与者的安全知识和安全行动。本研究结果表明广泛分发和使用“让安全发生”应用程序是有用的。试验注册号NCT02751203；于2016年4月26日注册。
