This study investigated Mexican immigrant parents' reports of perceived workplace discrimination and their children's behavior, parents' moods, and parent-child interactions. Parents of one hundred and thirty-eight 3- to 5-year-old children were asked to complete one survey daily for 2 weeks (N = 1,592 days). On days when fathers perceived discrimination, fathers and mothers reported more externalizing child behaviors, and mothers reported fewer positive child behaviors. When mothers perceived discrimination, they reported more externalizing child behaviors; fathers reported more internalizing child behaviors. Parents reported worse mood on days with perceived discrimination. Perceived discrimination was not strongly related to parent-child interactions. For fathers, but less so for mothers, those whose psychological acculturation indicated separation had more negative relations between daily perceived workplace discrimination and child and family outcomes.
