Abstract Previous studies have suggested that nature contact is a protective factor for problem behavior in children. However, there remains a significant gap in research exploring the reciprocal relationship between nature contact and children’s problem behavior, as well as the underlying mechanisms driving this relationship. This study employed a longitudinal three-wave design involving 516 children in China (268 girls, M ag e = 10.88 ± 0.66 years old at Time 3). Cross-lagged analyses indicated that nature contact and problem behavior negatively predicted each other over time, and prosocial behavior bidirectionally mediated the relationship between nature contact and problem behavior. These results provided evidence for the relationships among nature interaction, social development, and behavioral development in children. These findings suggested that promoting prosocial behavior could reduce problem behavior and enhance nature engagement, potentially serving as a strategy to foster comprehensive development in children.
