Although interest in studying prosocial behaviors among U.S. Latinx individuals has increased recently, there is still limited existing research with this population. Evidence shows that prosocial behaviors (actions intended to benefit others) are a marker of healthy social functioning and can both support positive development (such as academic achievement) and mitigate problematic outcomes (such as anxiety and depression). An important question is whether prosocial behavior is fostered by parents in ways that are specific to their cultural groups or through more universal aspects of parenting. A new longitudinal study in the United States examined relations among parenting, culture, and prosocial behaviors in U.S. Mexican youth.
