A preliminary study on validity and reliabily of the Defense Mechanisms Rating Scales Q-sort version (DMRS Q-sort)

This contribution focuses on the need to provide clinicians with a reliable and valid measure for detecting patient defense mechanisms “inside psychotherapy.” To avoid the limitations of existing methods, we designed a Q-sort based on the theoretical definitions and criteria of the Defense Mechanisms Rating Scales (DMRS-Q), but one that does not require transcripts of clinical interviews or sessions and may be applied without specific training on defenses. The DMRS-Q is sensitive to changes in psychotherapy and its scores correlate significantly with various aspects of mental functioning, making it potentially available for the psychotherapy process and outcome research as well.
