Vehicle license plate numbers and the shoulder belt use of front-seat occupants were recorded unobtrusively when parents delivered and picked up their children at a Montessori school during 5-day baseline, intervention, and follow-up phases. Practicing and presenting a 15-min safety belt skit increased the safety belt use of those 6 kindergarten children who were not consistent belt users 82% above their preintervention baseline belt use mean of 47%. The belt use of these children's parents (who watched the skit) increased to 56% above their baseline mean of 36%. Also, mean safety belt use of 11 primary school children who watched the skit increased to 70% above their baseline of 28%. Mean safety belt use of the older children's parents (who didn't watch the skit) remained at approximately 31% for each phase, regardless of whether children were vehicle occupants. The follow-up observations, taken 3 months after the intervention, revealed 60% belt use for the kindergartners, 48% for the primary school children, and 71% for the kindergartners' parents when the children were vehicle occupants but only 30% when the parents were driving alone.
在为期5天的基线期、干预期和随访期内，当家长在一所蒙特梭利学校接送孩子时，研究人员悄悄记录了车辆牌照号码以及前排乘客的安全带使用情况。排练并表演一个15分钟的安全带短剧后，6名原本使用安全带情况不稳定的幼儿园儿童的安全带使用率比干预前基线期47%的平均使用率提高了82%。这些孩子的家长（观看了短剧）的安全带使用率比基线期36%的平均使用率提高到了56%。此外，11名观看了短剧的小学生的安全带平均使用率比基线期28%提高到了70%。年龄较大孩子的家长（未观看短剧）的安全带平均使用率在每个阶段都保持在约31%，无论孩子是否乘车。干预3个月后的随访观察显示，当孩子乘车时，幼儿园儿童的安全带使用率为60%，小学生为48%，幼儿园儿童家长为71%；但当家长独自开车时，使用率仅为30%。
