目的了解小学生伤害回顾性调查中自我报告偏倚的程度,为探寻相对经济且真实的伤害调查方法提供依据。方法选取南昌市新建县某小学的部分班级小学生1681名为调查对象,在伤害发生的3d内受伤学生第1次填写伤害调查表,6个月后第2次填写,对2次填写问卷进行比较。结果小学生是否受伤害、伤害是有意造成的还是无意造成的、伤害种类、伤害地点和伤害部位共5个问题回答不一致率分别为17.7%,21.9%,44.2%,19.9%和22.2%。结论采用回顾性自我报告方式调查小学生伤害情况存在回忆偏倚。
Objective To understand the extent of self-report bias in a retrospective survey of injuries among primary school students, and to provide a basis for exploring a relatively economic and real injury investigation method. Methods A total of 1681 pupils from some primary school in Xinjian County, Nanchang were selected as subjects. The injured students filled in the injury questionnaire for the first time in 3 days and the second time in 6 months, and then compared the two questionnaires .

The inconsistent response rates of the five types of injury types, injury sites and injury sites were 17.7%, 21.9%, 44.2%, 19.9% and 22.2% respectively.
