We examined whether parents' content and style when discussing past positive and negative emotional experiences with their children were concurrently and predictively linked to prekindergarteners' social skills. Sixty-five low-income Spanish-speaking parent-child dyads discussed a past positive and negative emotional experience at the beginning of prekindergarten. Narratives were coded for parents' elaborative style and emotion resolution, cause, and attribution. Children's emotional and cognitive-processing words were also coded. Children's social problem-solving skills and prosocial behaviors were assessed at the beginning and at the end of prekindergarten. Concurrently, children's social problem-solving skills were related to parents' elaborative style when discussing positive emotional experiences and children's use of cognitive-processing words when discussing negative emotional experiences. Predictively, children whose parents offered resolutions when discussing negative emotional experiences at the beginning of prekindergarten had better social problem-solving skills at the end of prekindergarten. Parents who talked about causes or attributed emotions when discussing past emotional experiences did not necessarily have children with better social skills. Findings suggest that parents' scaffolding when discussing past positive and negative emotional experiences offers opportunities for prekindergarteners to develop social abilities crucial for school readiness.
