We advance a tripartite framework of language use to encompass language skills, the practice of language skills, and the subjective experiences associated with language use among Mexican-origin adolescents who function as language brokers by translating and interpreting for their English-limited parents. Using data collected over 2 waves from a sample of 604 adolescents (Wave 1: Mage = 12.41, SD = 0.97), this study identified 4 types of bilingual language broker profiles that capture the tripartite framework of language use: efficacious, moderate, ambivalent, and nonchalant. All 4 profiles emerged across waves and brokering recipients (i.e., mothers, fathers), except for Wave 1 brokering for mother, in which case only 3 profiles (i.e., efficacious, moderate, and ambivalent) emerged. Three profiles emerged across time: stable efficacious, stable moderate, and other. The efficacious and stable efficacious profiles showed the most consistent relation to adolescents' academic competence. Improving bilingual language proficiency, together with fostering more frequently positive brokering experiences, may be an avenue to improving academic competence among Mexican-origin adolescents in the United States.

墨西哥裔青少年的双语经纪人简介和学术能力。

我们推进了语言使用的三方框架，以涵盖语言技能、语言技能的实践以及与作为语言中介的墨西哥裔青少年的语言使用相关的主观体验，为英语水平有限的父母提供翻译和口译服务。本研究使用从 604 名青少年样本（第 1 波：Mage = 12.41，SD = 0.97）收集的超过 2 波数据，确定了 4 种类型的双语中介配置文件，它们捕捉了语言使用的三方框架：有效、适度、矛盾、和冷漠。所有 4 个配置文件都出现在波次和中介接收者（即母亲、父亲）中，除了第 1 波为母亲中介，在这种情况下只有 3 个配置文件（即有效、中等和矛盾）出现。随着时间的推移出现了三个配置文件：稳定有效，稳定中等，其他。有效和稳定的有效概况显示出与青少年学业能力最一致的关系。提高双语能力，同时培养更频繁的积极中介经验，可能是提高美国墨西哥裔青少年学术能力的途径。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
