目的 评价某学生近视影响因素调查问卷的复测一致性,为完善调查问卷设计提供参考。方法 采用自填方式进行调查,第一次调查结束后,间隔1个月对同一班级学生进行第二次调查,采用SPSS 15.0软件计算问卷复测一致率。结果 共调查了572名学生,其中男生占52.10%,女生占47.90%,4~6年级小学生46.50%,初中生占53.50%。问卷包含28道单选题,总体复测一致率约为56.49%,总体复测信度为0.573。不同性别间复测一致率差异无统计学意义(χ2 = 0.305,P=0.581),不同年级间一致率差异有统计学意义(χ2 =32.221,P＜0.001)。各类题目一致率由高到低依次是分类型题目(73.72%)、频次型题目(72.12%)、时间型题目(59.38%)和频率型题目(52.75%)。结论 问卷总体复测一致率不高,应针对复测一致率较低的题目进行修改。
Abstract
Objective To evaluate the retest consistency of the questionnaire on influencing factors of myopia among students,so as to provide reference for improving the design of the questionnaire. Methods The self-filling method was used for the survey.After the first survey,the second survey was conducted on the students in the same class at an interval of 1 month.The consistency rate of the questionnaire was calculated by SPSS 15.0 software. Results A total of 572 students were surveyed,including 52.10% boys and 47.90% girls,46.50% elementary students in grades 4-6 and 53.50% middle school students.The questionnaire contained 28 single choice questions,and the overal retest consistency rate was about 56.49%,and the overall retest reliability was 0.573.There was no difference in the consistency rate between different genders (χ2 = 0.305,P=0.581),but there was significant difference in the consistency rate between different grades (χ2 =32.221,P＜0.001).The consistency rates of various kinds of questions from high to low were Classified-type (73.72%),Count-type (72.12%),Time-type (59.38%) and Frequency-type (52.75%). Conclusion The overal retest consistency rate of the questionnaire is not high,the questions with low retest consistency should be modified.
