This study aimed to develop and validate a questionnaire to assess changes in dietary behaviors among school children in Jordan during the COVID-19 pandemic.
A cross-sectional study used a convenience sample of 253 school-aged children from public schools across Jordan. The dietary and lifestyle behavior inventory (DLBI) was developed, incorporating cultural and regional dietary preferences. The questionnaire's validity and reliability were assessed using the content validity index (CVI) and Cronbach's alpha for internal consistency. Exploratory factor analysis (EFA) was conducted to evaluate the underlying factor structure.
The DLBI demonstrated excellent content validity with a scale content validity index (S-CVI) of 0.997 and a high level of agreement among expert reviewers (total agreement = 116). Reliability analysis showed high internal consistency for dietary behavior scales, with Cronbach's alpha values exceeding 0.9 for fruit (0.869) and vegetable (0.916) consumption scales. Factor analysis revealed strong associations between dietary behavior variables, with factor loadings ranging from 0.688 to 0.889. The study identified significant reductions in physical activity levels among children, with an average Cronbach's alpha of 0.835 for physical activity-related items. The average time to complete the questionnaire was 15 minutes (SD = 5 minutes), with a completion rate of 45.6%.
The validated DLBI is a robust tool for assessing changes in dietary behaviors among school-aged children in Jordan during the COVID-19 pandemic. The findings highlight significant dietary patterns and physical activity shifts, emphasizing the need for targeted nutritional interventions.
本研究旨在开发并验证一份问卷，以评估新冠疫情期间约旦在校儿童饮食行为的变化。
一项横断面研究采用了来自约旦公立学校的253名学龄儿童的便利样本。开发了饮食与生活方式行为量表（DLBI），纳入了文化和地区饮食偏好。使用内容效度指数（CVI）和内部一致性的克朗巴哈系数评估问卷的效度和信度。进行探索性因素分析（EFA）以评估潜在因素结构。
DLBI显示出出色的内容效度，量表内容效度指数（S-CVI）为0.997，专家评审之间的一致性水平很高（总一致性 = 116）。信度分析表明饮食行为量表具有较高的内部一致性，水果（0.869）和蔬菜（0.916）消费量表的克朗巴哈系数值超过0.9。因素分析揭示了饮食行为变量之间的强关联，因素负荷范围为0.688至0.889。该研究发现儿童的身体活动水平显著下降，与身体活动相关项目的平均克朗巴哈系数为0.835。完成问卷的平均时间为15分钟（标准差 = 5分钟），完成率为45.6%。
经过验证的DLBI是评估新冠疫情期间约旦学龄儿童饮食行为变化的有力工具。研究结果突出了显著的饮食模式和身体活动变化，强调了针对性营养干预的必要性。
