This fourth book in the Prevention Practice Kit introduces the topic of prevention groups and illustrates how to apply that definition to real-world settings for counselors, psychologists, mental health workers, and prevention specialists working with groups in schools, hospitals, community organizations, and private practice. Readers will find practical suggestions on how to design, conduct, and organize prevention groups such as psychoeducational groups, group-centered prevention groups, and therapy prevention groups. Examples from research, along with case study examples, help to illustrate important concepts in both theory and practice.
