To examine the structural validity of the empirically and theoretically derived Satter Eating Competence Inventory (ecSI 2.0).
Confirmatory factor analyses with 3 databases and a merger with 3 additional data sets (n = 2,010) from demographically heterogeneous samples.
Findings supported retaining all 16 items and migration of the item I trust myself to eat enough for me from the Internal Regulation to Eating Attitudes subscales, providing 4 distinct but correlated subscales and an adequately fitting model, χ(98) = 1,364.27, P < .001, comparative fit index = .91, root mean square error of approximation = .07, 95% confidence interval, 0.07-0.08, standardized root mean square residual = .05.
Psychometric integrity of the 16-item ecSI 2.0 was affirmed. Continued examination is recommended with cultural and linguistically diverse samples and network analyses to identify dynamic interactions among items.
检验经验和理论得出的 Satter 进食能力量表（ecSI 2.0）的结构效度。
使用 3 个数据库进行验证性因子分析，并与来自人口统计学异质样本的 3 个额外数据集合并（n=2010）。
研究结果支持保留所有 16 个项目，并将项目“我相信自己有能力为我吃足够的食物”从内部调节迁移到进食态度子量表，提供了 4 个不同但相关的子量表和一个适当拟合的模型，χ（98）=1364.27，P<0.001，比较拟合指数=0.91，均方根误差近似值=0.07，95%置信区间为 0.07-0.08，标准化均方根残差=0.05。
16 项 ecSI 2.0 的心理计量学完整性得到了肯定。建议继续使用文化和语言多样化的样本进行进一步的检验，并进行网络分析以确定项目之间的动态相互作用。
