Abstract：
(1) Background: We aimed to analyze the dimensionality, internal consistency, and structural validity of the Preschool Eating, Lifestyle, and Sleeping Attitudes Scale (PRELSA Scale), which is an instrument that was designed to measure obesogenic behaviors. (2) Methods: We carried out an observational study by means of an online survey. The PRELSA Scale consists of 13 dimensions and 60 items relating to the most common obesogenic behaviors and attitudes. Additionally, we obtained sociodemographic characteristics and concrete habits from the sample. We obtained the responses of 791 parents and caregivers of preschool children between 2 and 6 years of age in Andalusia (southern Spain). We analyzed dimensionality through an Exploratory Factor Analysis (EFA), consistency through Cronbach\'s Alpha, structural validity through a Confirmatory Factor Analysis (CFA), and measurement invariance with multigroup CFA models. (3) Results: The EFA showed a 14-dimensional structure with 48 items. The internal consistency was acceptable in all dimensions (Cronbach\'s Alpha range of 0.72 to 0.97). The structure was confirmed in the CFA with good fit indices (CFI and TLI > 0.9 and RMSEA < 0.05). We ensured that the scale had measurement invariance regarding education, income, and marital status. (4) Conclusions: The PRELSA Scale shows promising properties that have the potential to measure obesogenic behaviors in Spain, which could be the basis for future interventions associated with the prevention of childhood obesity in healthcare and educational settings.
摘要：
(1)背景：我们旨在分析维度，内部一致性，和学前饮食的结构效度，生活方式,和睡眠态度量表（PRELSA量表），这是一种用来测量肥胖行为的工具。（2）方法：我们通过在线调查进行了观察性研究。PRELSA量表由13个维度和60个与最常见的致胖行为和态度有关的项目组成。此外,我们从样本中获得了社会人口统计学特征和具体习惯。我们获得了安达卢西亚（西班牙南部）2至6岁学龄前儿童的791名父母和照顾者的答复。我们通过探索性因子分析(EFA)分析了维度，通过克朗巴赫的阿尔法一致性，通过验证性因子分析(CFA)的结构效度，多组CFA模型的测量不变性。(3)结果:EFA显示有48个项目的14维结构。内部稠度在所有尺寸上都是可接受的(Cronbach的Alpha范围为0.72至0.97)。在CFA中以良好的拟合指数(CFI和TLI>0.9和RMSEA<0.05)证实了结构。我们确保量表在教育方面具有测量不变性，收入,和婚姻状况。（4）结论：PRELSA量表显示出有希望的特性，有可能在西班牙测量致胖行为，这可能是未来在医疗保健和教育环境中与预防儿童肥胖相关的干预措施的基础。
