Peer group treatment has been subject to two main lines of criticism. Some suggest any program which aggregates antisocial youth inevitably fosters negative peer influence. Others are concerned that certain peer programs are based on coercive peer confrontation. Positive Peer Culture [PPC] is an antidote to both of these varieties of toxic group cultures. The authors draw on group research, extensive clinical practice, and a strength-based value perspective to describe the specific process of developing positive group cultures.
