This book features materials that are not based on or related to any particular treatment program. They are intended to be versatile, flexible, and used in many ways for many populations. Some of the stimuli are tried-and-true with some new variations. Decisions about whom to use it with, how, and why, are in the hands, judgment, and creativity of the clinician. This book invites therapists to think critically and study and apply the best evidence and practice guidelines from the current professional literature.
