This study focuses on constructing and confirming the reliability of a scale that integrates four key constructs from educational psychology, which are integral to interpreter training. This effort contributes to the niche of “metacognitive interpreter studies” and illustrates the beneficial use of structural equation modeling (SEM) within the realm of Interpreting Studies. A survey served as the primary tool for data collection, with 299 university students, native in Chinese and proficient in English as a second language, from various Chinese-speaking regions, participating voluntarily. The SEM analysis substantiated the scale’s validity and reliability. The findings suggest that the scale is a promising tool for assessing how interpreting learners in higher education institutions utilize skills related to the four educational psychology constructs. The research also demonstrates the effective application of SEM in the field of Interpreting Studies.
