Research Findings: For the current study, formal mediation procedures were adapted for families and parents were trained and asked to mediate their children's disputes; control group parents intervened as they normally would. Conflict negotiations with parents and their children (ages 3½-11 years) occurring 3 and 7 weeks following training, and with children alone 7 months later, were videotaped and coded. Parents were able to learn and implement mediation techniques: They were more likely to discuss the children's emotions and less likely to blame them for past transgressions and to propose solutions to the children's conflicts than were control group parents. Children in the mediation group learned from their parents and were more likely to ask each other for plans to resolve the conflict, to generate plans, and to discuss their own and their siblings' emotions than were control group children. Younger mediation group children were specifically empowered, as both they and their older siblings were more likely to discuss the younger children's interests and emotions and to resolve issues so that younger siblings' goals were achieved. Practice or Policy: Our results replicate and strengthen previous findings of the benefits of conflict mediation for children's conflict resolution abilities.
