Guided by a process model of parenting and the integrative model, this study examined sources of emotional support (i.e., partner, maternal, paternal) as related to stress and satisfaction resulting from the parenting role in a sample of Mexican-origin young adult parents who participated in the National Longitudinal Study of Adolescent to Adult Health (Add Health) during Wave IV. Participants were male and female parents (26-35 years of age; 59% female; N = 737) who had children and a partner. Results from structural equation modeling revealed support from mothers as salient; high levels of maternal support were associated with high levels of parenting satisfaction. Tests of indirect effects suggested that parenting satisfaction played an intervening role in the link between maternal support and parenting stress. The pattern of results held across levels of linguistic acculturation but varied by gender. Understanding the mechanisms that predict parenting stress and satisfaction within the Mexican-origin population may help in the identification of culturally sensitive intervention strategies.
