目的编制适用于学龄期儿童的用眼卫生行为调查问卷,并进行信度和效度检验。方法通过文献回顾、前期数据分析、专家咨询等方法,编制学龄期儿童用眼行为问卷。采用整群抽样方法,于2015年12月抽取温州市鹿城区某小学四、五年级学生288人进行问卷调查,采用独立样本t检验、相关分析、内部一致性检验和因子分析等统计学方法对问卷进行项目分析、信度和效度检验。结果三轮专家咨询的积极系数均为100%,权威系数(CR)=0.92,各指标专家意见变异系数(CV)<0.25,协调系数(W)=0.43(P<0.01)。经项目分析,《学龄期儿童用眼卫生行为调查问卷》确立7个维度:用眼距离、读写姿势、视近光线、阅读环境、读写用眼、视频用眼和眼放松行为,共28个条目。探索性因子分析显示累积方差贡献率为63.76%。问卷内容效度指数为0.89,问卷Cronbach’sα系数为0.820,分半系数为0.844,重测信度系数为0.682。结论《学龄期儿童用眼行为调查问卷》具有良好的信度和效度,可考虑作为儿童用眼行为调查的测量工具。
Objective To prepare a questionnaire about eye health behavior for school-age children and to test its reliability and validity. Methods Through the literature review, pre-data analysis, expert advice and other methods, the preparation of school-age children with eye behavior questionnaire. A cluster sampling method was used to conduct a questionnaire survey on 288 students in Grade Four and Grade Five of a primary school in Lucheng District of Wenzhou City in December 2015. Statistical methods such as independent sample t test, correlation analysis, internal consistency test and factor analysis Questionnaire for project analysis, reliability and validity test. Results The positive coefficients of three rounds of expert consultations were all 100%. The authority coefficient (CR) was 0.92. The coefficient of variation (CV) <0.25 and the coordination coefficient (W) were 0.43 (P <0.01). The project analysis, “school-age children with eye health behavior questionnaire” to establish seven dimensions: eye distance, reading and writing position, depending on the light, reading environment, reading and writing eyes, eyes and eyes with video relaxation behavior, a total of 28 Entries. Exploratory factor analysis showed that the cumulative variance contribution rate was 63.76%. Questionnaire content validity index was 0.89, the questionnaire Cronbach’s α coefficient was 0.820, the half-coefficient was 0.844, the test-retest reliability coefficient was 0.682. Conclusion The Questionnaire on Ocular Behavior in School Children has good reliability and validity and can be considered as a measurement tool for children’s eye behavior investigation.
