Validation of L2 grit among Chinese EFL high school students and its enduring effect on achievements: A bifactor model approach

open access: yesFrontiers in Psychology, 2022
The current study seeks to validate L2 grit measure among 637 Chinese senior middle school students using a bifactor modeling approach. To do so, we first assessed and compared four alternative measurement models including CFA, bifactor CFA, ESEM, and ...

Exploratory structural equation modeling: a streamlined step by step approach using the R Project software

open access: yesBMC Psychiatry, 2023
Confirmatory Factor Analysis (CFA) has been a popular yet limited approach to assessing latent factor structures. Despite items rarely loading exclusively on one latent factor in multifactorial scales, CFA assumes all indicators/items should load ...

Modelling the Incremental Value of Personality Facets: The Domains‐Incremental Facets‐Acquiescence Bifactor Model

open access: yesEuropean Journal of Personality, EarlyView., 2020
Abstract Personality can be described at different levels of abstraction. Whereas the Big Five domains are the dominant level of analysis, several researchers have called for more fine‐grained approaches, such as facet‐level analysis. Personality facets allow more comprehensive descriptions, more accurate predictions of outcomes, and a better ...
