The Linking the Interests of Parent and Teachers (LIFT) program, mentioned earlier, successfully lowered levels of adolescent aggression during peer interaction. An experimental study of LIFT evaluated the impact of the program on delinquent behaviors of 600 first- and fifth-graders from high juvenile crime neighborhoods. The program targets certain youth social behaviors, such as opposition, deviance, and social ineptitude, and parenting practices, such as disciplining and monitoring (Eddy et al., 2000). Results indicate that participants in the LIFT program were rated by teachers as less aggressive towards peers during play and social interaction than those in the control group.
