In early 1974, an exhaustive survey “A Self-Report Survey: Preliminary study of Participants in Erhard Seminars Training” by R. Ornstein, C. Swencionis, A. Deikman, and R. Morris was completed by 10.5% of the est graduate population. The survey asked graduates to report their experience of health and well-being after the est training and their experience of health and well-being the year before the training…. Respondents reported strong positive health and well-being changes since taking the est Standard Training, especially in the areas of psychological health and well-being.
