The purpose of this study was to evaluate the construct validity of a version of the ecSatter Inventory (ecSI), a measure of eating competence (EC), as adapted for use in a low-income (LI) population.
Females (n=507), aged 18 to 45 years, living in households with a history of participating in the Supplemental Nutrition Assistance Program completed a web-based survey that included the ecSI for LI (ecSI/LI) and valid measures of cognitive and affective eating behavior, food preference and practice, and food preparation.
Most correlations and differences between eating competent and non-eating competent categories and among EC tertiles were compatible with hypothesized relationships. ecSI/LI scores were positively related with self-reported physical activity, food acceptance, fruit and vegetable intake, and food planning/resource management. ecSI/LI scores were negatively associated with body mass index, dissatisfaction with body weight, tendency to overeat in response to external or emotional stimuli, and indices of psychosocial attributes related to disordered eating.
The ecSI/LI is a valid measure of EC for low-income females and provides a tool for researchers and educators to assess intervention outcomes and further explore the EC construct.
本研究旨在评估经过改编以适用于低收入人群的 ecSatter 清单（ecSI）版本的结构效度，该量表用于衡量饮食能力（EC）。
年龄在 18 至 45 岁之间的女性（n=507），居住在有参与补充营养援助计划历史的家庭中，完成了一项基于网络的调查，其中包括适用于低收入人群的 ecSI（ecSI/LI）以及经过验证的认知和情感饮食行为、食物偏好和实践、以及食物准备的有效衡量标准。
在有饮食能力和无饮食能力类别之间，以及在 EC 三分位组之间，大多数相关性和差异与假设的关系一致。ecSI/LI 评分与自我报告的身体活动、食物接受度、水果和蔬菜摄入量以及食物计划/资源管理呈正相关。ecSI/LI 评分与身体质量指数、对体重的不满、对外界或情绪刺激过度进食的倾向以及与饮食失调相关的心理社会属性指标呈负相关。
ecSI/LI 是衡量低收入女性 EC 的有效工具，为研究人员和教育工作者提供了一种评估干预效果和进一步探索 EC 结构的工具。
