The Psychometric Validation of Turkish Versions of Four Scales: The Foreign Language Enjoyment, Peace of Mind, Boredom, and Classroom Anxiety Scales

In this study, we present psychometrically validated Turkish versions of four popular foreign language learner emotion scales. They include the Foreign Language Classroom Peace of Mind Scale (Zhou et al., 2023), the Short-Form Foreign Language Enjoyment Scale (Botes et al., 2021), the Short-Form Foreign Language Classroom Anxiety Scale (Botes et al., 2022a), and the Foreign Language Classroom Boredom Scale (Li et al., 2023). We collected data from 1202 Turkish to English as a Foreign Language (EFL) learners. Cross-validation analyses confirmed the scales' applicability and reliability among these Turkish learners, and, measurement invariance (configural, metric, and scalar) analyses revealed consistency in respondents' emotional experiences across diverse educational levels, enabling valid cross-group comparisons. Although strict invariance across student subgroups was not achieved, our findings provide Turkish researchers with four valid instruments for collecting emotional data from Turkish learners. The scale means and relationships between the four emotions measured with these adapted scales were comparable to those established in previous studies.
