Leiderman , PsyD, ABPP, FAACP, CGP, AGPA-F, Director, Neurofeedback and Psychological Services, PC, President, American Group Psychotherapy Association "With the recent designation of Group Psychology and Group Psychotherapy as a Recognized Specialty by the American Psychological Association, this book is timely and needed. Collins-Greene, Riva, and Lefforge have assembled renown group psychotherapists with extensive experience in the supervision of group psychotherapy to create an in-depth resource on the supervision of group psychotherapy covering everything from the history and models of group psychotherapy supervision, specific competencies for supervisors, ethical issues, and multicultural considerations.
