A well-known intervention treatment is the Scared Straight Treatment. According to research done by Scott Lilienfeld, this type of intervention is often harmful because of juvenile offenders’ vicarious exposure to criminal role models and the possibility of increased resentment in reaction to the confrontational interactions. It has been reasoned that the most efficient interventions are those that not only separate at-risk teens from anti-social peers, and place them instead with pro-social ones, but also simultaneously improve their home environment by training parents with appropriate parenting styles.
