Two independent teams of judges used a general category system of good moments and an RET category system of good moments, respectively, in assessing all client statements in two audiotaped sessions conducted by Dr. Albert Ellis. A comparison of the findings from using the two category systems identified four unique features of RET. The features involved (a) unique RET good moments given by the RET literature; (b) additional general categories of good moments that are also obtained by RET; (c) unique RET methods of obtaining insight-understanding; and (d) unique RET methods of promoting behavior change.
