Joint first authorship.Joint senior authorship.Social-emotional ability is key to the well-being and future success of children; however, disparities in social-emotional development during an individual’s early age can last a lifetime, which is particularly evident among children living in poverty-stricken areas. We aimed to determine the effectiveness, cost-effectiveness, and feasibility of a group-based intervention called the Care Group on social-emotional development for families living in poverty-stricken counties.
