Influence of Maladaptive Personality Traits on Women's Posttraumatic Cognitions of IPV

Objective: Intimate partner violence (IPV) is a problem for women worldwide. One factor that affects the severity of women's distress in the aftermath of IPV is how they make meaning of the violence they experienced. Posttraumatic meaning-making takes the form of 3 distinct posttraumatic cognitions: self-blame, other negative thoughts about oneself, and negative thoughts about the world. Women's posttraumatic cognitions in the aftermath of IPV are in part a function of personality. Research on personality and posttraumatic cognitions has focused primarily on the influence of normative personality traits, although maladaptive personality traits are more common in clinical assessment. One of the most common models of maladaptive traits is DSM-5's Alternative Model of Personality Disorder (AMPD), which contains 5 maladaptive variants of normative personality traits (Antagonism, Detachment, Disinhibition, Negative Affect, and Psychoticism). Although there is increasing research on the AMPD traits in general, there is limited research on the influence of these traits on women's response to IPV specifically. Method: In this study we examine the association between AMPD traits and posttraumatic cognitions of IPV in a sample of women exposed to IPV (N = 199) using a Bayesian approach to multiple regressions. Results: Results suggest that IPV and Negative Affect were the primary influences on all 3 IPV-related posttraumatic cognitions and that other traits had differential effects depending on the type of posttraumatic cognition under analysis. Conclusions: These findings clarify our understanding of individual differences in posttraumatic response and have implications for the treatment of women exposed to IPV. Clinical Impact Statement In this study we examined how personality traits influence women's cognitive responses to intimate partner violence (IPV), finding that both how severe the IPV was and trait-related negative emotions were the primary influence on women's IPV response, although this differed depending on the specific response.
