Summary: With a selective focus on immigrant children and families from the Child Development Supplement of the Panel Study of Income Dynamics (N = 189), this dissertation relied on path analyses to garner empirical support for a theoretically-based model linking social capital with family perceptions and attributions, home- and school-based family educational involvement, and student outcomes (i.e., achievement, behavior problems, positive behavior). Results demonstrated that social support was positively associated with immigrant families' self-efficacy and perceptions of opportunities for involvement. In turn, families with higher levels of self-efficacy engaged in more home-based involvement activities. Children in immigrant families with a role construction around education in alignment with the dominant culture of the U.S. demonstrated better child achievement but worse behavior outcomes than children from immigrant families with a role construction unaligned with dominant U.S. culture. Lastly, in contrast to extant literature, immigrant families' school-based educational involvement was not associated with any family perceptions or attributes or child outcomes. Implications of both significant and null findings are discussed for developmental science, practice, and policy.
