This book examines prevention groups by addressing both the theoretical principles underlying group-centered prevention and the techniques needed to train scientist-practitioners and clinicians to conduct such groups. It describes group-centered prevention in three different settings: health, school, and family counseling. Opening with a definition of group-centered prevention, the book examines the theoretical principles on which group-centered prevention is built. Group-centered prevention combines learning and counseling into the same group program. In addition, the book provides ready-to-use training sessions for mastering group principles. The results of trying to conduct prevention groups without proper training are also explored. The final chapters focus on how group-centered prevention can be used in a variety of programming areas and offer recommendations for ensuring the success of prevention groups. This book is a must-have resource for scientist-practitioners, clinicians, and academics across such related fields as school psychology, childhood education, social work, public health as well as group counseling, motivational psychology and family studies.
