Abstract: This article introduces the clover model, a research-based developmental model of resilience and psychopathology related to the prevention of aggressive behavior and the promotion of resiliency in adolescents. It describes how social cognitions and emotions function differently at different periods of adolescent development and influence problem behavior, such as aggression and antisocial conduct, as well as resiliency. A prototypical prevention program based on the model is discussed. Finally, we describe an organized after-school activity, also based on the model, as a concrete example of this developmentally differentiated intervention approach.
