School children may be at risk of physical health problems associated with desktop, laptop and tablet computer use. There are some interventions designed to educate children about ergonomic practices when using computers. A common limitation of past intervention studies has been the lack of a valid and reliable questionnaire to determine effectiveness of the intervention.
The aim of this study was to develop a valid and reliable self-report measure to assess primary school children's knowledge, attitudes and behaviours related to healthy computer use.
A mixed methods approach was used to develop the questionnaire and test its psychometric properties. A convenience sample of 440 primary school children in Year 5 (aged 9-11 years) was used in the development and validation of the questionnaire.
The final questionnaire comprised 56 items across the three subscales of knowledge, attitudes and behaviour. The questionnaire was shown to have good content validity and adequate test-retest reliability. Internal consistency was adequate for the attitude items, but low for the knowledge items.
This study produced a valid and reliable tool, using a health promotion framework, for measuring primary school children's knowledge, attitudes and behaviours related to healthy computing.
学童可能面临与使用台式电脑、笔记本电脑和平板电脑相关的身体健康问题风险。有一些干预措施旨在教育儿童在使用电脑时遵循人体工程学做法。过去干预研究的一个常见局限性是缺乏一个有效且可靠的问卷来确定干预措施的有效性。
本研究的目的是开发一种有效且可靠的自我报告测量工具，以评估小学生与健康使用电脑相关的知识、态度和行为。
采用混合方法来开发问卷并测试其心理测量特性。在问卷的开发和验证过程中，使用了一个由440名五年级（9至11岁）小学生组成的便利样本。
最终问卷包括知识、态度和行为三个子量表中的56个项目。该问卷显示出良好的内容效度和足够的重测信度。态度项目的内部一致性足够，但知识项目的内部一致性较低。
本研究使用健康促进框架产生了一种有效且可靠的工具，用于测量小学生与健康使用电脑相关的知识、态度和行为。
