Scale Analysis

The Category List of Good Moments Scale (CLGMS-12) was developed by Mahrer and Nadler in 1986 to identify and categorize significant in-session phenomena that contribute to the progress of the therapeutic process.

Purpose of the Scale

The CLGMS-12 was created with the purpose of identifying and categorizing significant in-session phenomena that contribute to the progress of the therapeutic process. The scale consists of twelve categories of in-session phenomena that have been identified as important therapeutic moments by theorists, clinicians, and researchers. Some of the in-session moments identified through the use of this scale include emotional expression, changes in problematic behaviors, the presence of a good therapeutic relationship, and insight.

Scoring of Items

The scale is designed to be used specifically by trained raters who listen to video-recorded or audio-recorded therapy sessions and simultaneously read the transcript of the session. They have access to a special manual detailing the categories of the scale and providing instructions for identifying and categorizing these moments. To test the reliability of the measurement, a group of raters (at least three) is needed to assess the level of agreement among them.

Statistical Analysis

The CLGMS-12 serves as a research tool in the context of the psychotherapeutic process in individual adult psychotherapy. Raters are asked to evaluate whether the client’s statement—i.e., the client’s utterance that occurs between two therapeutic interventions—contains a significant in-session moment and to categorize it into one or more categories of the scale.

Validity and Reliability

The scale has been adapted to Greek and translated based on the process of reverse independent translation. The psychometric characteristics of the scale in its original form are satisfactory. The Kappa reliability index for the scale among raters ranges from 0.72 to 0.77. The corresponding Greek values in a preliminary study ranged from 0.69 to 0.79.
