Language brokering is a common practice for Latino youth with immigrant parents. Yet little is known about how youth's feelings about this responsibility contribute to the parent-adolescent relationship. In this study, we examined the longitudinal associations between language brokering attitudes and parent-adolescent closeness in a sample of Latino early adolescents (n = 813, Maget1 = 12.32, SDt1 = 0.59), while taking into account language brokering frequency and the possible moderating role of sex. Results suggested that sex of the adolescent was a moderator. Specifically, younger males who felt closer to their parents had more positive attitudes toward language brokering, which dissipated as they aged. Furthermore, language brokering frequency had a delayed positive contribution to language brokering attitudes and parent-adolescent closeness, which was stronger for males than females. Results are discussed in terms of how age and gender cultural norms contribute to the relation between language brokering and parent-adolescent closeness.
