Defense Mechanisms Rating Scales-Self-Report-30 (DMRS-SR-30)


Assessment name:  Defense Mechanisms Rating Scales-Self-Report-30 (DMRS-SR-30)

Scale overview: The Defense Mechanisms Rating Scales-Self-Report-30 (DMRS-SR-30) is a 30-item self-administered measure of psychological defense mechanisms that assesses overall defensive functioning. The 30-items were developed based on the Q-Sort version known as the DMRS-Q (Di Giuseppe et al., 2014).

Authors: Tracy A. Prout, Mariagrazia Di Giuseppe, Sigal Zilcha-Mano, J. Christopher

Perry & Ciro Conversano


Response Type: Items are rated on a scale of frequency as follows:

0 = Not at all

1 = Rarely/slightly

2 = Sometimes/somewhat

3 = Often/ a lot

4 = Very often/ much


Scale items

There are 30 items related to defense mechanisms. The items represent defense mechanisms and are organized into categories based on three factors.

Factor 1. Mature Defenses in the High-Adaptive level









Factor 2: Mental Inhibition and Avoidance – Obsessional, Neurotic and Disavowal levels

Isolation of affects





Reaction formation



Autistic fantasy


3. Depressive and Immature defenses





Projective identification

Splitting of other’s image

Splitting of self-image

Passive aggression

Help-rejecting complaining

Acting out



Reliability and Validity

See Di Giuseppe et al. (2020) and Prout et al. (2022) articles below for psychometric data on the DMRS-30-SR scale. The researchers have provided the results of a factor analysis, coefficient alpha values, and correlations with other measures.


The results yield several scores. The ODF (Overall Defensive Functioning) score is based on all 30 items. Prout et al. (2022) reported ODF (M = 5.43, SD = 0.61) alpha .90 in their sample of 1,549 participants.
