Youth from immigrant families often translate or interpret materials for their parents who lack proficiency in the dominant language of the mainstream society. However, evidence remains mixed regarding whether such a language brokering role is promotive or disruptive for youth’s well-being. This meta-analysis synthesized 65 studies (1,242 effect sizes, 17,791 individuals; grand M_age = 16.68, SD_age = 4.78) to examine whether, how, and when brokering frequency and feelings were related to well-being. Language brokering frequency was inversely associated with youth’s positive family relationships (r = −.10) and socioemotional outcomes (r = −.10) and positively related to youth’s acculturation stress (r = .06). However, positive or negative language brokering feelings were stronger predictors of youth’ well-being or maladjustment (|r| = .10–.29). The associations between language brokering frequency and youth’s adjustment also varied across subgroups, with the effects of frequent language brokering being more detrimental for European immigrant-origin (vs. Latinx), female (vs. male), and foreign-born (vs. native-born) youth. These findings underscore the need for a nuanced understanding of the impacts of youth language brokering. Finally, practical and policy implications are discussed.

语言中介和移民出身青年的福祉：荟萃分析评论。

来自移民家庭的年轻人经常为不熟练掌握主流社会主流语言的父母翻译或口译材料。然而，关于这种语言中介作用是促进还是破坏青年福祉的证据仍然混杂。这项荟萃分析综合了 65 项研究（1,242 项效应大小，17,791 人；大M_年龄= 16.68，SD_年龄= 4.78），以检验中介频率和感受是否、如何以及何时与幸福感相关。语言中介频率与青年的积极家庭关系 ( r = −.10) 和社会情感结果 ( r = −.10) 呈负相关，与青年的文化适应压力呈正相关 (r = .06)。然而，积极或消极的语言调解感受是青少年幸福感或适应不良的更强预测因子 (| r | = .10–.29)。语言中介频率与青年适应之间的关联也因亚组而异，频繁的语言中介的影响对欧洲移民起源（相对于拉丁裔）、女性（相对于男性）和外国出生（相对于本地人）更为不利-出生）青年。这些发现强调需要对青年语言中介的影响有细微的了解。最后，讨论了实际和政策影响。
