OBJECTIVE
Using item response theory, we sought to evaluate measurement invariance of language brokering extent and attitudes in 3 linguistic minority groups of adolescents.
METHOD
The sample included 765 (302 Chinese American, 327 Korean American, and 136 Mexican American; 57% females) ninth graders from immigrant families.
RESULTS
Differential item functioning was detected for several items, and we retained items with equivalent parameters across 3 groups. The final items showed adequate internal consistency reliability and criterion validity.
CONCLUSION
The refined scale is cross-ethnically invariant and appropriate for use with Chinese-American, Korean-American, and Mexican-American adolescents to compare their language brokering experiences. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
目的
运用项目反应理论，我们旨在评估 3 个少数族裔青少年群体中语言中介程度和态度的测量不变性。
方法
样本包括 765 名（302 名中国裔美国人、327 名韩裔美国人和 136 名墨西哥裔美国人；57%为女性）来自移民家庭的九年级学生。
结果
对几项项目进行了差异项目功能检测，我们保留了在 3 组中具有等效参数的项目。最终的项目显示出足够的内部一致性信度和标准有效性。
结论
经过改进的量表在跨文化上是不变的，适用于美籍华裔、韩裔美国人和墨西哥裔美国青少年，以比较他们的语言中介经验。
