Parental attachment and close teacher-child relationships offer a protective mechanism to promote language development among bilingual preschool children from economically disadvantaged backgrounds. Research has shown that language skills are an integral part of resilience for young children. This is the first study to examine parental acculturation, parent-child attachment, and teacherchild relationships as predictors of English and Spanish oral language skills. Participants consisted of 468 Hispanic American preschool children, aged 3 to 5 years, from low-income families of an urban public school district in the Northeast. Findings suggest that children's relationships with parents and teachers significantly contribute to their bilingual language skills. Higher quality teacherchild relationships were associated with higher levels of language skills over and above quality parental attachments. The implications of the findings are discussed.

This is especially important for young immigrant children who are exposed to poverty, learning a second language, acculturation stress, and other potential stressors that place them at risk for social-emotional, communication, and learning difficulties in school.For preschool children, competence is measured by their ability to communicate wants and needs, establish and maintain relationships, solve problems, and demonstrate school readiness, all of which are interrelated with and rooted in social-emotional development (Bergin & Bergin, 2009). In turn, attachment relationships provide a strong foundation for the development of competence in preschool. Moreover, language serves as a bonding agent between children and their attachment figures, and culture influences communication styles and the quality of affect in attachment relationships (Schieffelin & Eisenberg, 1984). Simultaneously, the development of preschoolers' language skills is enhanced by the nature of these attachment interactions (Piker & Rex, 2008;Saunders & O'Brien, 2006).In school, preschoolers' adaptive coping and success are influenced through parent-child attachments and by attachment-like relationships with teachers. Language serves as an operative measure of school readiness and preschool success. Therefore, it is essential that school psychologists understand the "impact of early social-emotional relationships on cognitive-linguistic-affective structures used by the child to construct views of the world, self, and others" (Kennedy & Kennedy, 2004, p. 247). In particular, building immigrant children's competence to succeed in school requires an understanding of their attachment relationships with their parents and teachers within the context of language and cultural factors.Developing language skills to its full potential is challenging when children live in impoverished environments (NICHD Early Childhood Rese...
