Unintentional injury is the leading cause of death for those aged 0 years to 19 years. St. Louis Children's Hospital created Safety Land, a comprehensive injury prevention intervention which is provided during summer months. This program uses a life-size board game to teach safety education to children in ages 5 years to 11 years. The purpose of this study was to evaluate the effect of Safety Land on safety knowledge in children that participated in the intervention.
St. Louis Children's Hospital identified ZIP codes with the highest use of the emergency room for injury. Daycares and summer camps within these ZIP codes were targeted for the Safety Land intervention. A multiple choice pretest and posttest survey was designed to measure knowledge change within program participants. Students were selected for testing based on site availably. Within these sites, a convenience sample of children was selected for pretesting and posttesting. Safety Land staff conducted the pretest a week before the intervention, and the posttest was administered the week after the intervention. A total knowledge score was calculated to determine overall knowledge change. Descriptive statistics and independent-samples t tests were conducted to determine statistical significance of change in knowledge (p < 0.05) for each question.
Between May 2014 and August 2016, 3,866 children participated in Safety Land. A total of 310 children completed the pretest and 274 completed the posttest. Mean test scores increased from 66.7% to 85.1% and independent-samples t test of the total knowledge score was significant (p < 0.05) between pretest and posttest values.
Findings suggest that this intervention is effective in increasing the knowledge of safety behaviors for children receiving the curriculum during the summer months. Further research should focus on long-term behavior changes in these youth.
意外伤害是 0 至 19 岁人群死亡的主要原因。圣路易斯儿童医院创建了安全乐园，这是一项综合性的伤害预防干预措施，在夏季提供。该计划使用真人大小的棋盘游戏向 5 至 11 岁的儿童教授安全教育。本研究旨在评估安全乐园对参与干预的儿童安全知识的影响。
圣路易斯儿童医院确定了急诊室使用率最高的邮政编码。这些邮政编码内的日托中心和夏令营是安全乐园干预的目标。设计了多项选择题前测和后测调查，以衡量计划参与者的知识变化。根据场地可用性选择学生进行测试。在这些地点中，选择了一个方便的样本进行前测和后测。安全乐园工作人员在干预前一周进行前测，干预后一周进行后测。计算总知识得分以确定整体知识变化。进行描述性统计和独立样本 t 检验，以确定每个问题的知识变化（p<0.05）的统计学意义。
2014 年 5 月至 2016 年 8 月期间，共有 3866 名儿童参加了安全乐园。共有 310 名儿童完成了前测，274 名儿童完成了后测。平均测试分数从 66.7%增加到 85.1%，前测和后测之间的总知识分数的独立样本 t 检验具有统计学意义（p<0.05）。
研究结果表明，该干预措施在增加接受暑期课程的儿童安全行为知识方面是有效的。应进一步研究这些年轻人的长期行为变化。
