Maladaptive (dark-side) and adaptive (bright-side) personality traits and defense styles

This study explores the relationship between bright- and dark-side personality traits and four major styles of defense mechanisms (DMs) as this relationship remains unexplored and important in understanding the DMs. In all, 435 adult working participants (241 men; 194 women; Mean age 46.06 yrs) mainly in middle management jobs, completed a 78-item, six-trait measure of bright-side personality (HPTI: High Potential Type Indicator), a 25-item five-trait measure of the dark-side personality (PID-5;BF: DSM-5-Brief Form) and 88-item, four-styles measure of defense mechanisms (Defense Style Questionnaire). The aim was to examine demographic (sex, age, education), ideological and personality trait correlates of the DMs. It was hypothesized that the dark-side traits, particularly Detachment would be most strongly related to the DMs. Thereafter, a hierarchical linear regression was performed with each DM factor as criterion and predictors being demography, ideology, self-esteem as well as bright- and dark-side personality traits. Detachment was associated with all DMs, particularly Maladaptive (r = 0.68) and Image Distorting Style (r = 0.38) while Conscientiousness was associated with none. One implication concerns the assessment of DMs by standard tests. Limitations are acknowledged and include method invariance and sample homogeneity.
