The Mediating Role of the Dark Triad Between Life History Strategy and Perceived Stress Factors.

Life History Theory posits early-life adversities affect personality development partway through sensitizing individuals to certain environmental cues, thus influencing the person's responses to different stressors. We therefore hypothesized that life history strategy affects perceived distress and self-efficiency in coping through certain personality traits. The concept of the Dark Triad describes specific forms of personalities found to be associated with faster life strategies and perceived stress. Hence, the aim of our study was to examine the possible mediator role of the Dark Triad traits on the relationship between life strategies and perceived stress. A sample of 432 (133 males) under- and postgraduate students (aged between 18 and 34 years, M= 23.4, SD = 3.9) answered the Short-Form of the Arizona Life History Battery, the Mini-K, the Perceived Stress Scale, and the Short Dark Triad. Multiple linear regression and subsequent mediation analyses showed significant mediation effects of Dark Triad traits on both perceived distress and perceived coping. Our results indicate that these personality traits are part of the process in which faster life strategies predict higher level of perceived stress and lower levels of coping ability.
