Valid and reliable research tools to assess children's and adolescent's health-related behaviour are highly needed across the globe. Rapid economic development, globalization, and associated lifestyle challenges observed in most countries support the need for high-quality evidence in adolescents to target health-promoting policies and interventions. This study aims to examine the test-retest reliability of selected well-being, physical and screen-time related siting activities, and eating behaviour items of the Health Behaviour in School-Aged Children (HBSC) questionnaire in a sample of Vietnamese adolescents.
Data were collected in autumn 2018 in Vietnam (3-week interval). The sample consisted of 410 adolescents (41.0% of boys; mean age = 12.61; SD = 1.24).Test-retest reliability was evaluated using the single measure Intraclass Correlation Coefficients (ICC) and Cohen's kappa statistic stratified by sex, grade and place of residence (urban or rural).
The reliability analyses of the well-being items were poor to good ICC values (0.43-0.79) and moderate to large Cohen's kappa values (0.33-0.77). The physical activity and eating behaviour items were moderate (ICC = 0.54-0.65; Cohen's kappa = 0.38-0.57). The screen-time related siting activities items were moderate to large (ICC = 0.51-0.72; Cohen's kappa = 0.42-0.53). There was more item stability among females than males. The social media item was not as stable for 6 graders (ICC = 0.45) compared with older adolescents (ICC 0.68-0.77).
The findings show that with regards to age, sex and place of residence, self-reported health, life satisfaction, physical and screen-time related siting activities, as well as eating behaviour items of the HBSC questionnaire have a sufficient test-retest reliability to be used in national self-report surveys for Vietnamese adolescents while health complaints items showed borderline reliability.
在全球范围内，需要有效的、可靠的研究工具来评估儿童和青少年与健康相关的行为。大多数国家都经历了快速的经济发展、全球化以及与之相关的生活方式挑战，这支持了在青少年中使用高质量证据来制定促进健康的政策和干预措施的必要性。本研究旨在检验越南青少年健康行为监测研究（HBSC）问卷中幸福感、身体活动和久坐行为以及饮食行为相关部分的部分项目的重测信度。
数据于 2018 年秋季在越南收集（间隔 3 周）。样本包括 410 名青少年（男生占 41.0%；平均年龄 12.61 岁；标准差 1.24 岁）。使用单测量组内相关系数（ICC）和 Cohen's kappa 统计量（按性别、年级和居住地（城市或农村）分层）评估重测信度。
幸福感项目的可靠性分析得出了从差到好的 ICC 值（0.43-0.79）和从中等到大的 Cohen's kappa 值（0.33-0.77）。身体活动和饮食行为项目的 ICC 值为中等（0.54-0.65），Cohen's kappa 值为中等（0.38-0.57）。与屏幕时间相关的久坐行为项目的 ICC 值为中等至较大（0.51-0.72；Cohen's kappa 值为 0.42-0.53）。女性的项目稳定性比男性高。与年龄较大的青少年相比，六年级学生的社交媒体项目的稳定性较差（ICC=0.45）。
研究结果表明，根据年龄、性别和居住地，HBSC 问卷中自我报告的健康、生活满意度、身体活动和久坐行为以及饮食行为的项目具有足够的重测信度，可用于越南青少年的全国自我报告调查，而健康问题项目的可靠性则处于边缘状态。
