Research Findings: Prosocial behavior in early childhood can be assessed by various informants and methodologies, but the information each provides may differ in meaningful ways. The present study measured and compared young children's (N = 486; age: M = 48.51 months, SD = 8.22) prosocial behavior based on parent reports, teacher reports, and…
