幼儿家长对家庭意外伤害状态认识测量工具的研究

A study on the reliability and validity of a tool to measure the situation awareness of toddlers' parents towards domestic injuries

目的检验幼儿家长对家庭意外伤害状态认识测量工具的信度与效度。方法用照片提示家庭环境和危险物品,用自行设计的"幼儿家长对家庭意外伤害状态认识的调查表"对234名家长进行调查,同时,询问在过去的两周之间"吓一跳"事件的次数。结果各项目正解率为13%-92%,由照片提示的危险物品引起的"吓一跳"事件占总数的69%,各危险状态认识的得分在高、低组家长间体验的"吓一跳"事件次数差异有统计学意义;两周间重测信度总体为0.79,6种危险状态的重测信度在0.59-0.92之间。结论重测信度、内容构成效度、外在效度基本得到了检验,因项目得分分散较大,所以不宜计总分,但可以作为测量指标使用。

Objective To test the reliability and validity of a tool to measure the situation awareness of toddler＇s parents towards domestic injuries （TMSATPDI）. Methods A total of 234 toddler＇s parents were recruited and investigated with photos about home environment and hazards related to domestic injuries,and a self-designed questionnaire about the situation awareness towards domestic injuries. Moreover,the parents were asked to report the times of frightened events related to the toddlers in the past two weeks. Results The correct rate of each item in situation awareness questionnaire was ranged from 13% to 99%. The number of frightened events related to the hazards in the photos accounted for 69% of the total number. There was significant difference on the number of frightened events between the parents with high and low score of situation awareness. The total test-retest reliability within two weeks was 0.79. The test-retest reliability of the six situations was ranged from 0.59 to 0.92. Conclusion This study confirmed the test-retest reliability ,internal validity and external validity of the tool. However, the variance of the scores was high in some items. Therefore, it is not recommended to compute the total score. But it can be sued as indices to measure situation awareness of toddler＇s parents towards domestic injuries.
