Significant variation exists in bilinguals’ experiences with code-switching, from dense code-switching in multiple interactional contexts to minimal switching. Although recent research has demonstrated that a bilingual’s experience with code-switching is a crucial factor for determining both linguistic and cognitive behaviors, there currently is no commonly accepted method of measuring of a bilingual’s code-switching practices. Responding to this need, this paper presents a new tool to assess a bilingual’s experience and engagement with code-switching – the Bilingual Code-Switching Profile (BCSP) – and assesses its validity and reliability. The BCSP incorporates a multifaceted conceptualization of code-switching experience, drawing on previous research in bilingual proficiency, and addresses a bilingual’s code-switching history, use, proficiency, and attitudes. To assess the validity and reliability of the BCSP, Spanish–English bilinguals (N = 454) from a wide range of ages, ethnic backgrounds, national origins, and language dominance profiles completed the questionnaire. Results of an exploratory factor analysis and intraclass correlation on test-retest data (N = 248) demonstrate that the BCSP is a valid and reliable method of assessing a bilingual’s code-switching profile. The BCSP can be easily and practically incorporated into future research on bilinguals to provide a systematic measure of an individual’s code-switching profile.

双语语码转换配置文件 (BCSP)

双语者的语码转换体验存在显着差异，从多种交互环境中的密集语码转换到最少的语码转换。尽管最近的研究表明，双语者的语码转换经验是决定语言和认知行为的关键因素，但目前还没有普遍接受的方法来衡量双语者的语码转换实践。针对这一需求，本文提出了一种新工具来评估双语者的语码转换体验和参与度——双语语码转换档案（BCSP）——并评估其有效性和可靠性。 BCSP 吸收了语码转换经验的多方面概念，借鉴了双语能力的先前研究，并讨论了双语者的语码转换历史、使用、熟练程度和态度。为了评估 BCSP 的有效性和可靠性，来自不同年龄、种族背景、民族血统和语言优势概况的西班牙语-英语双语者 (N = 454) 完成了调查问卷。探索性因素分析和重测数据的组内相关性 (N = 248) 结果表明，BCSP 是评估双语语码转换概况的有效且可靠的方法。 BCSP 可以轻松实用地纳入未来的双语研究中，以提供对个人语码转换概况的系统测量。
