在文献检索和访谈的基础上,提出有关编制适用于我国小学生水域安全调研的知信行(KAP)问卷的理论构想。以此为基础,编制小学生水域安全知信行初始问卷。经初测(N=495)和正式测量(N=2 554),运用探索性因素分析方法筛选条目,用克朗巴赫法评价同质性信度,据内容效度比评价内容效度,用探索性和验证性因素分析方法评价结构效度。问卷包含4个维度(水域安全知识、技能、态度和高危行为)共39个条目。问卷的信效度检验结果表明,问卷的因素结构、同质性信度、内容效度和结构效度均达到心理测量学的要求。小学生水域安全知信行问卷具有较为满意的信、效度,较好地反映了问卷设计的理论构想。
Preparing of a questionnaire about water safety KAP for pupils was envisaged theoretically on the basis of literature retrieval and interviews. A questionnaire about water safety KAP for pupils was pre- pared. Entries were screened using an exploratory factor analysis method after an initial test ( N = 495 ) and formal measurement (N = 2 554) were done. The homogeneity reliabilities were evaluated using the Cronbach method. The content validities were evaluated on the baisis of content validity ratios. The struc- ture validity was evaluated by exploratory and confirmatory factor analysis. The questionnaire contains 39 entries in 4 dimensions (water safety knowledge, skills, attitudes and risk behaviors). Test results of reliability and validity of questionnaire show that the requirements of psychometrics are satisfied.
