The COVID-19 pandemic impacted considerably university students' health and well-being, justifying the development and use of validated measuring tools to analyse and assess mental/physical health, and well-being throughout consecutive confinements (or lockdowns), or any other endured stressful periods. This study aims to describe the translation, the cultural adaptation, and the validation of a short questionnaire to assess changes in lifestyle-related behavior, due to the COVID-19 pandemic, in Portuguese university students. We enrolled 128 university students (mean age: 38.3 [13.0] studying at/attending the Portuguese Catholic University). The validation study included Cronbach alpha for the whole scale, corrected item-total correlations, and Cronbach alpha to evaluate the scale reliability whenever items were deleted. Exploratory factor analysis was performed, and 3 factors were extracted through the principal component extraction with varimax rotation. Communalities were also observed. The mean and standard deviation of the total questionnaire score was -1.73 (6.65). No difference was seen between genders. However, participants who already had COVID-19 symptoms, and participants who perceived their health as worse than in the prepandemic period, presented lower questionnaire scores. Internal consistency of 0.74, as measured by Cronbach alpha, was considered as acceptable. Exploratory factor analysis corroborated the validity of the tool. This short questionnaire could be applied to detect changes in lifestyle-related behavior throughout stressful situations in a Portuguese university student's population.
新冠疫情对大学生的健康和幸福产生了重大影响，这使得开发和使用经过验证的测量工具来分析和评估在连续的隔离（或封锁）期间或任何其他经历的压力时期的心理/身体健康及幸福变得合理。本研究旨在描述一份简短问卷的翻译、文化适应和验证过程，该问卷用于评估葡萄牙大学生因新冠疫情导致的与生活方式相关行为的变化。我们招募了128名大学生（平均年龄：38.3岁[13.0]，就读于葡萄牙天主教大学）。验证研究包括计算整个量表的克朗巴哈α系数、校正后的项目-总分相关性，以及在删除项目时评估量表信度的克朗巴哈α系数。进行了探索性因子分析，并通过主成分提取和方差最大化旋转提取出3个因子。还观察了共同度。问卷总得分的均值和标准差为-1.73（6.65）。性别之间未观察到差异。然而，已经出现新冠症状的参与者以及认为自己的健康状况比疫情前更差的参与者，问卷得分较低。通过克朗巴哈α系数测量的内部一致性为0.74，被认为是可接受的。探索性因子分析证实了该工具的有效性。这份简短问卷可用于检测葡萄牙大学生群体在压力情境下与生活方式相关行为的变化。
