Positive Peer Pressure
A number of programs utilize the system of positive peer groups.
The idea is that a person would adapt the general guidelines from a group of peers they have been isolated with. The problem with this system is that people in general adapt to the peer group they are in based on their present situation. What will happen once a person is removed from the positive peer group and returned to the negative peer group, the person came from.
The task is to make the person who have been adapting well in a so-called positive peer group adapt poorly back home in the unchanged social circles which did create the need for this person to be removed from the community.
