Healthy Computing Questionnaire for Children (HCQC)

The Healthy Computing Questionnaire for Children is a 56 item outcome measure that was developed, trialled and validated with a sample of 440 primary school students aged 9-11 years. It contains three subscales of knowledge, attitudes and behaviour. It is appropriate to use at a single point in time to assess children’s knowledge, attitudes and behaviour related to healthy use of computer technology, and also to evaluate changes over time.

A panel of four experts who held advanced qualifications and extensive work or research experience in the fields of education, ergonomics, occupational therapy and health promotion was consulted to confirm the content validity of the measure. A sample of 13 school children were used to pilot a preliminary version of the measure and provide feedback on length, clarity and readability of the items. Three hundred and sixty four school children participating in the study completed the final version of the HCQC and their responses were used to confirm the construct validity and internal consistency of the items. Test-retest reliability (measured two weeks apart) was confirmed with a sample of 63 school children.

《儿童健康计算问卷（Healthy Computing Questionnaire for Children）》是一款包含56个条目的结果测评工具，其开发、试用与验证工作基于440名9至11岁的小学生样本。该问卷涵盖知识、态度与行为三个子量表，既适用于单次测评时点下儿童健康使用计算机技术相关的知识、态度与行为评估，也可用于追踪其随时间产生的变化。

本研究组建了由教育、工效学（ergonomics）、作业治疗与健康促进领域具备高级资质及丰富工作/研究经验的4名专家组成的专家小组，以确认该测评工具的内容效度（content validity）。研究招募13名学龄儿童对问卷的初步版本开展试点测试，收集其针对条目长度、清晰度与可读性的反馈。最终，364名参与本研究的学龄儿童完成了《儿童健康计算问卷》终版，其作答数据被用于验证问卷的结构效度（construct validity）与条目内部一致性（internal consistency）。此外，研究对63名学龄儿童进行了间隔两周的重测，结果证实了该问卷的重测信度（test-retest reliability）。
