Machiavellianism and Intimate Partner Violence Perpetration: A Systematic Review and Meta-Analysis

This systematic review and meta-analysis estimated the size of the relationship between Machiavellianism and intimate partner violence (IPV) perpetration. Further, we explored whether the strength of this relationship varied depending on IPV type (i.e., physical, psychological, sexual, and cyber), and perpetrator gender. Systematic searches of Medline Complete, PsycInfo, Scopus, and Web of Science databases were conducted on July 4, 2023. Studies were included if they were a peer-reviewed published paper or unpublished dissertation, in English, included a measure of Machiavellianism and IPV perpetration, and reported the relationship between these variables. Study quality was assessed using the AXIS tool. Nineteen studies (N = 9,464) were included in a random-effects meta-analysis revealing a significant, weak, positive correlation between Machiavellianism and IPV perpetration (r = .16, 95% CI [0.11, 0.21], p < .001). Machiavellianism had a significant, weak, positive relationship with cyber (r = .25, 95% CI [0.17, 0.32], p < .001), psychological (r = .20, 95% CI [0.15, 0.24], p < .001), and sexual IPV (r = .10, 95% CI [0.02, 0.19], p = .020). No significant relationship was found for physical IPV. There was no significant difference in the strength of the relationship between women and men. These findings are limited by the measures being self-report, heterogeneity across studies, and the cross-sectional nature of the included studies which limits the understanding of causal pathways. Nonetheless, this meta-analysis shows a link between Machiavellianism and IPV perpetration, and future research should examine how this knowledge may be used to reduce IPV perpetration.

Dating App Facilitated Sexual Assault: A Retrospective Review of Sexual Assault Medical Forensic Examination Charts

Dating app facilitated sexual assault (DAppSA) is a concerning phenomenon with minimal published research. This retrospective study explored if DAppSAs were different than other sexual assaults (SAs) committed by acquaintances through a review of 3,413 sexual assault medical forensic examination (SAMFE) charts from 2017 to 2020 in a Mountain West state in the United States. Routine Activities Theory and Confluence Model of sexual aggression provided the theoretical framework for the study. Inclusion criteria for DAppSA cases included (1) victim was 14 years of age or older; (2) victim indicated meeting the perpetrator on a dating app; (3) SA occurred at initial in-person meeting; and (4) victim had a SAMFE with SA kit evidence collection. DAppSAs (n = 274) represented 8.02% of overall cases and 13.92% of acquaintance SAs (n = 1,968). DAppSA victims had unique characteristics including a higher percentage of male victims (7.5%), college students (22.2%), and victims with self-reported mental illness (MI) (59.6%). Victims were less likely to fight back during the assault with lower percentages of kicking (5.8%) and hitting (9%). DAppSA victims and perpetrators were less likely to use drugs or alcohol before or during the assault. DAppSAs were found to be more violent SAs with increased strangulation (32.4%); assaultive/penetrative acts; and victim injuries, especially anogenital and breast injuries. Unique and troubling differences were found in DAppSA cases than other SAs committed by acquaintances. Due to the increased violent nature of DAppSAs, the researchers propose that sexual predators use dating apps as hunting grounds for vulnerable victims. Recommendations to address dating app safety concerns, influence dating app usage policies, and improve care to survivors are discussed through systems-based and trauma-informed approaches.
