Defense mechanisms and Defense Mechanism Test (DMT)

What is a defense mechanism?

In the psychoanalytic hypothesis, a defense mechanism is an oblivious mental instrument that diminishes tension emerging from inadmissible or possibly hurtful boosts. Sound individuals ordinarily utilize distinctive protection instruments all through life. A safeguard instrument becomes obsessive just when its industrious utilize prompts maladaptive conduct with the end goal that the physical or emotional wellness of the individual is unfavorably influenced. Among the reasons for personality guard systems is to ensure the psyche/self/conscience from nervousness or social assents or to furnish an asylum from a circumstance with which one can’t as of now adapt. Read the complete article to know more about the Defense Mechanism Test.

Introduction to Defense Mechanism Test

The Defense Mechanism Test (DMT) is a percept-genetic(cf. Kragh and Smith, 1970) and projective test based assumedly tension inciting TAT-like pictures, which are exposed through a tachistoscope utilizing slowly increasing exposure span extending from 5 ms (subconscious) to 2,000ms (supraliminal). The presumably frequently utilized Defense Mechanism Test picture (cf. Olff, 1991) portrays in the middle a high school person(the Hero, in DMT phrasing) of similar sex as the person being tried, and in the fringe a more established and threatening person (the Peripheral individual, in DMT wording), of the same sex as the Hero and the individual being tried. This situation is intended to portray an Oedipal danger (a furious mother or father) which should prompt various sorts of”precognitive guarded association” (Kragh, 1962a) and activate safeguard systems normal for the perceiver.

Employment of Defense Mechanism Test

It ought to be underscored that the Defense Mechanism Test has been employed in various ways as respects device, improvement pictures, number of introductions and presentation times, guidelines, subsequent inquiries, and assessment of the DMT conventions (seeOlff, 1991, for an audit).

Further, though the first DMT (cf., Kragh, 1985) depends on the classification of people’s responses into different psychoanalytical guards, some recent endeavors have been made to break down DMT information with-out the creation of such a classification however to base the examination on the exact structure of normally happening reaction categories.

Accordingly, Cooper and Kline (1989; see additionally Cooper, 1991)have built up an “equitably scored” variation of the DMT that lays on G-investigation to evaluate the similitude between people’s reaction profiles just as a Q-factor examination of these individual likeness measures to acquire individual factors rather than factors dependent on relationships among variables.

In a comparable vein, Armelius and Sundbom (1991, see also Henningsson, Sundbom, Armelius, and Erdberg, 2001) have employed incomplete least squares head segments and discriminant investigation to plan individuals into a multidimensional space based on their unique DMT reactions. In the present study, notwithstanding, we have utilized strategies in line with the unique system as communicated in Kragh’s (1985)official DMT manual.

Details about DMT

Despite the fact that the Defense Mechanism Test (DMT) has been being used for practically 50 years, there are still very opposing perspectives about whether it is a dependable instrument, and assuming this is the case, what it truly gauges. In this manner, in view of information from 39 female understudies, we originally inspected DMT between coder dependability by breaking down the arrangement among prepared adjudicators in their coding of similar DMT conventions.

Second, we built an “equal” photographic picture that held all basic traits of the first and broke down DMT equal test unwavering quality.

Third, we inspected the developed legitimacy of the DMT by (a) utilizing three self-report safeguard component inventories and examining the intercorrelations between DMT guard scores and comparing protections in these instruments, (b) considering the connections between DMT reactions and scores on quality and state uneasiness, and (c) relating DMT-guard scores to proportions of confidence.

The fundamental outcomes demonstrated that the DMT can be coded with high dependability via prepared coders, that the equal test unwavering quality is unsuitably contrasted with conventional psychometric norms, that there is sure generalizability in the number of perceptual mutilations that individuals show starting with one picture then onto the next, and that the development approval gave pitiful exact proof to the end that the DMT estimates what it implies to gauge, that is, mental protection instruments.

Current situation

The current investigation has inspected different dependability and con-struct legitimacy attributes of the DMT. As to reliability, one of our examinations zeroed in on between coder dependability, that is, the arrangement among DMT-encountered coders’ appraisals of the same DMT conventions.

The outcomes uncovered that this aspect of dependability was agreeable for all DMT defenses with just a single exemption. In this manner, except for the protection class Isolation, the unwavering quality coefficients fell inside the span detailed by Kragh (1985) in the DMT manual. Be that as it may, this source doesn’t give any clear description of how the dependability files have been computed (yet observe, e.g., Ozolins, 1989).

At any rate, it appears clear that DMT-prepared therapists appear to accomplish high concurrent in their DMT appraisals even though it is very evident that for some protection classes (Introjection of other gender =incorrect sex of the apparent individual; Introjection of another object = mistaken time of apparent individual), the coding rules are target to the point that difference among decides is almost inconceivable.

The ramifications of the high between coder reliability are that one essential part of DMT unwavering quality issatisfied which would make it conceivable to distinguish inert relationships among DMT and different develops.

Even though there seems, by all accounts, to be no relations between people’s responses to the DMT and their scores on different self-report safeguard component polls (which are correlated among themselves), it is unreasonable to close that this finding definitely nullifies the DMT. By classical psychometric reasoning, the end would be that the DMT needs to develop legitimacy.

In any case, the circumstance is complicated by the way that ongoing exploration in different psycho-sensible spaces (e.g., memory, thought processes, mentalities, prejudice)has made a differentiation between unequivocal (slow, intentional, conscious) and understood (quick, programmed, unconscious)aspects of a similar marvel (see, e.g., Greenwald & Banaji, 1995).


75 juvenile mental patients were determined to have the perceptual projective test the Defense Mechanism Test (DMT) and furthermore as indicated by Kernberg’s hypothesis of character association (PO). The test conventions were scored in regard to 130 DMT factors and examined by methods for incomplete least squares (PLS) discriminant examination. The goal was to attempt to isolate the three sorts of PO, crazy (PPO), fringe (BPO), and psychotic (NPO) by methods for the DMT and furthermore to contrast the outcomes and a comparative report in grown-up mental patients. The outcomes indicated that it is conceivable to isolate altogether the three gatherings of the PO. The BPO bunch appeared to be heterogeneous. The outcomes were genuinely like those got with grown-up mental patients. The general outcomes upheld the simultaneous legitimacy of Kernberg’s hypothesis of PO and for the DMT also. The DMT is by all accounts a helpful demonstrative technique in regard to young adult mental patients.
