In 2005 Rubinstein compared large-group awareness training to certain principles of cognitive therapy, such as the idea that people can change their lives by reinterpreting the way they view external circumstances.In the 1997 collection of essays Consumer Research: Postcards from the edge, discussing behavioral and economic studies, the authors contrast the "enclosed locations" used in Large Group Awareness Trainings with the relatively open environment of a "variety store".The Handbook of Group Psychotherapy (1994) characterised Large Group Awareness Training as focusing on "philosophical, psychological and ethical issues" relating "to personal effectiveness, decision-making, personal responsibility, and commitment."Psychologist Dennis Coon's textbook, Psychology: A Journey, defines the term "Large-group awareness training" as referring to programs claiming "to increase self-awareness and facilitate constructive personal change". Coon further defines Large Group Awareness Training in his book Introduction to Psychology. Coon and Mitterer emphasize the commercial nature of several LGAT organizations.
