Adolescents from Mexican immigrant families are often embedded in a challenging social environment and experience multiple contextual stressors, including economic stress, discrimination, and foreigner stress. We consider how the effects of these contextual stressors may be amplified or diminished for adolescents who function as language brokers, interpreting and mediating for their English-limited parents. Using two waves of survey data collected from a sample (N = 604 at Wave 1; N = 483 at Wave 2) of Mexican American adolescents with ages ranging from 11 to 15 (M = 12.41, 54% female), four distinct brokering-stress profiles were identified. Latent profile analyses revealed that with moderate levels of contextual stress, adolescents with more positive language brokering experiences (protective group) demonstrated more favorable outcomes than those with neutral language brokering experiences (moderate group) and those who did not involve themselves as frequently in language brokering activities (less-involved group). In contrast, high levels of contextual stress, coupled with more negative language brokering experiences (risk group), produced the least favorable outcomes among adolescents.
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: M age ϭ 12.41, SD ϭ 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.
The intergenerational transmission of executive function may be enhanced or interrupted by culturally salient environmental stressors that shape the practice of executive function in the family. Building upon past research, the current study tests whether culturally relevant stressors such as economic stress and foreigner stress have a direct effect on adolescent executive function, as well as whether they modify the intergenerational transmission of mother–child executive function (i.e., working memory, inhibitory control, and shifting) in low-income Mexican immigrant families. The sample consists of 179 Mexican American adolescents (Mage = 17.03 years; SDage = 0.83; 58% females) and their Mexico-born mothers (Mage = 43.25 years; SDage = 5.90). Results show that mothers’ perceived economic stress is associated with poor inhibitory control in adolescents. Low levels of mothers’ perceived foreigner stress related to a stronger association between mothers’ and adolescents’ working memory, while high levels of mothers’ perceived foreigner stress related to enhanced intergenerational transmission of poor shifting ability. Study findings demonstrate the prominence of perceived foreigner stress as a contextually relevant factor moderating the intergenerational transmission of mother–child executive function in low-income Mexican immigrant families.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
