ABSTRACT
"Change" implies a deviation from some baseline consistently outside the normal limits of fluctuation of an act, action sequence, or feeling state. Behavioral change for that individual would consist of responses that fell outside the distribution and clustered about a new mean. Change measures were intercorrelated and factor analyzed, and the factors that emerged seemed to be defined by the instruments used. Therapeutic outcome data almost always consist at least of before and after measures. Many investigators use difference or change scores as a means of contrasting the experimental and control groups. The hypothesis of change related to one of the goals of therapy and was open to specific test. The patients stressed changes in insight, attitude, and behavioral alterations, while the therapists emphasized behavior and symptom relief. Most change was seen in the self, which was also the most talked about in therapy.
