Amazon.com description: Product Description: This one-of-a-kind road map for students and new group leaders combines a unique developmental model of brief group process--based on the generic chronological processes of a group--with modifications for specific clinical populations. The chronological-process model was developed and researched in the authors' own laboratories, empirically tested for more than a decade, and employed successfully for years. This clearly identifiable process underlies all small groups, making it appropriate in all settings, serving all populations.
