This article outlines the development of a 16-item instrument for measuring language learner’s foreign language self-efficacy (SE) concerning their speaking and listening skills through repeated administrations to groups of Japanese tertiary students. Responses were analysed through the Rasch model, which allows researchers to investigate unidimensionality of each proposed component, as well as the functioning of individual items. Logit scores from Rasch were used for a regression analysis of listening SE with listening proficiency test data, and a correlation study with speaking SE and speaking proficiency scores of a subset of participants. The results suggest that the two proposed components in the instrument are unidimensional and are able to differentiate between different levels of SE among participants. Also, there are low to moderate correlations between learners’ aural/oral SE and their language proficiency.

本文概述了一种 16 项工具的开发，该工具通过对日本大学生群体的反复管理来衡量语言学习者的外语自我效能感 (SE)，这些工具涉及他们的口语和听力技能。通过 Rasch 模型分析响应，该模型允许研究人员调查每个提议组件的一维性，以及单个项目的功能。Rasch 的 Logit 分数用于听力 SE 与听力能力测试数据的回归分析，以及口语 SE 和部分参与者的口语能力分数的相关性研究。结果表明，该工具中提出的两个组件是一维的，并且能够区分参与者之间不同水平的 SE。还，
