J Nutr Educ Behav. 2019 Sep;51(8):1003-1010. doi: 10.1016/j.jneb.2019.05.287. Epub 2019 Jul 24.


Objective: To examine the structural validity of the empirically and theoretically derived Satter Eating Competence Inventory (ecSI 2.0).

Methods: Confirmatory factor analyses with 3 databases and a merger with 3 additional data sets (n = 2,010) from demographically heterogeneous samples.

Results: 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, χ2(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.

Conclusion and implications: 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.

Keywords: eating behavior; factor analysis; nutrition surveys; psychometrics; survey development.
