Emotional intimate partner violence (IPV) refers to behaviors such as controlling, isolating, and punishing the partner using fear, humiliation, and manipulation. Emotional IPV affects both men and women worldwide and poses serious risks to well-being. The Dark Triad personality traits (narcissism, psychopathy, Machiavellianism) may increase the likelihood of perpetrating emotional IPV in a relationship. Moreover, the satisfaction and frustration of the basic psychological needs —autonomy, relatedness, and competence — may also play a role in IPV perpetration. The present study investigated the effects of dark triad traits and basic psychological need satisfaction and frustration on emotional IPV perpetration. 382 Turkish adults (M= 41.05, SD= 10.63, 208 female) who were in a romantic relationship for over one month participated in the study. Participants completed online self-report questionnaires, including the Short Dark Triad Scale, the Multidimensional Measure of Emotional Abuse, and the Basic Psychological Need Satisfaction and Frustration Scale. Two hierarchical multiple regression analyses were conducted, predicting emotional IPV perpetration from the dark triad traits and the dimensions of basic psychological need satisfaction and frustration, statistically controlling for age and gender. Results of the first model revealed that higher levels of psychopathy and frustration of the need for autonomy predicted higher levels of emotional IPV perpetration. In the second model, psychopathy predicted IPV perpetration, whereas psychological need satisfaction dimensions did not. Across both models, being male and older were associated with greater IPV perpetration. Overall, the findings suggest that emotional IPV may be influenced by both the perpetrator's personality traits and the level of frustration of their basic psychological needs. Addressing these factors may contribute to reducing the risk of emotional IPV.
