The present study examined how acculturation, mental health problems, and parenting stress are associated with two dimensions of father involvement longitudinally for Latino and Chinese immigrant fathers using a nationally representative sample of young children and their resident fathers from the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B). After controlling for a variety of individual and demographic characteristics and previous levels of father involvement, results from multiple group structural equation modeling revealed that immigrant fathers' English proficiency is negatively associated with care-taking involvement at 2 years, but positively associated with care-taking involvement at 4 years. Interestingly, mothers' English proficiency is also positively associated with fathers' care-taking involvement at 2 years. In addition, fathers' US citizenship is positively associated with care-taking involvement at 2 years. Finally, mothers' US citizenship is negatively associated with fathers' literacy or language involvement at 2 years. In contrast with the hypotheses, no significant differences between Latino and Chinese immigrant fathers were found. Findings suggest that some dimensions of acculturation affect different dimensions of father involvement across different groups of immigrants, and the impacts may remain significant even four years after the child birth.
