An experimental design was used to test the effectiveness of three modalities of instruction in pediatricians' offices. Parents in the experimental and control groups were asked if their children wore a car seat restraint on the way to the office. The parents in the experimental group were encouraged to have their children use restraints via one of the following methods: a pamphlet alone; a pamphlet and verbal instruction by the pediatrician; or a pamphlet, verbal instruction, and a brief slide-tape show. The parents were contacted by telephone, mail, or in person two weeks later and asked if their child used a restraint on their last car trip. There were no statistically significant changes in behavior in any of the gourps. Although the group that received all forms of instruction had the highest mean score, the greatest increase occurred with the control group.
采用了一种实验设计来测试在儿科医生办公室中三种教学方式的有效性。实验小组和控制小组的家长被问及他们的孩子在来办公室的路上是否使用了汽车座椅约束装置。通过以下方法之一鼓励实验组的家长让孩子使用约束装置：仅发放一份宣传册；发放宣传册并由儿科医生进行口头指导；或发放宣传册、进行口头指导并播放一段简短的幻灯片录像。两周后通过电话、邮件或亲自联系家长，询问他们的孩子在上一次乘车旅行中是否使用了约束装置。任何一组的行为都没有统计学上的显著变化。虽然接受了所有形式指导的小组平均得分最高，但控制小组的增长幅度最大。
