RESUMO
Language proficiencies have implications for how parents and children can communicate effectively and how culture and heritage can be transferred across generations. Previous research has sought to understand the relationship between parent language (mainstream, heritage) proficiencies and the ethnic-racial orientation of their children, though prior studies have not investigated the relationship between child language proficiencies and parent ethnic-racial orientation. This study examined the actor-partner effects of Latine mother-child dyads (N = 175; youth mean age = 12.86 years) regarding their proficiencies in English and Spanish and their Latine and White orientations. Our results revealed that youth Spanish language proficiency was positively linked to youth White orientation, and youth English proficiency was also positively associated with youth White orientation but only in instances when youth-reported acculturation conflict was lower or average. There were two partner effects observed, with youth English proficiency positively relating to mother's White orientation and mothers' Spanish proficiency being negatively related to youth White orientation. Regarding Latine orientation, both English and Spanish were positively related to greater Latine orientation for both mothers and their children. However, at higher levels of mother-reported acculturation conflict, higher mother English proficiency was related to lower youth Latine orientation. Overall, language proficiencies for Latine mothers and their children contribute to the development of bicultural orientations, though varying degrees of acculturation conflict can have differential impacts on these linkages.
