Validating the foreign language enjoyment scale for young learners: An exploratory structural equation modeling approach

Foreign language enjoyment (FLE) has garnered scholarly attention within the framework of positive psychology. However, FLE-related studies have predominantly focused on adult learners, with little exploration into FLE among young language learners (YLLs). Consequently, little is known about the factorial structure of FLE and its sources for YLLs. This study aims to develop and validate the foreign language enjoyment scale (FLES) designed for YLLs by comparing four models: confirmatory factor analysis (CFA), bifactor CFA, ESEM, and bifactor ESEM, based on Alamer's (2022) guidelines for ESEM. 510 Japanese elementary ESL learners in the 5th and 6th grades participated in this study. The analysis of the four models revealed that the bifactor ESEM outperformed the others in terms of model fit and comparative indices, identifying a three-factor model of FLE, which is consistent with prior studies on adult learners. The findings from this study not only contribute to further understanding of FLE within a less-studied population but also advance methodological approaches for scale validation in applied linguistics.
