Perceptual defenses and self-rated personality disorders: a multivariate analysis

Area of Science:

• Psychology
• Psychiatry
• Clinical Psychology

Background:

• Defense mechanisms are psychological strategies used to cope with distress.
• Personality disorders are characterized by enduring patterns of inner experience and behavior.
• Understanding the interplay between defense mechanisms and personality disorders is crucial for effective treatment.

Purpose of the Study:

• To investigate the relationship between specific defense mechanisms and personality disorders.
• To explore correlations using the Defense Mechanism Test and Millon's Inventory-II.
• To analyze these relationships in a cohort of psychiatric outpatients.

Main Methods:

• Utilized the Defense Mechanism Test and Millon's Inventory-II.
• Assessed 100 nonpsychotic psychiatric outpatients.
• Employed nonparametric correlation and multiple regression analyses.

Main Results:

• Few significant positive correlations were observed between defense mechanisms (e.g., barrier isolation) and personality disorder traits.
• Multiple regression analysis yielded limited significant results, often in a negative direction.
• Unexpected findings suggest potential confounding factors in the study population.

Conclusions:

• The study found weak associations between defense mechanisms and personality disorders in this clinical sample.
• Elevated personality scale scores due to emotional distress may have reduced interindividual differences, impacting results.
• Further research is needed to clarify these complex relationships in psychiatrically distressed populations.
