Objective: Despite legislative developments within the UK seeking to reduce domestic abuse, not only are reports of domestic abuse increasing, but both survivors and perpetrators of domestic abuse engage in self-harming behavior and suicide attempts. Some of whom ultimately die by suicide. As such, identifying those at risk of self-harm within this population is paramount. Method: This study presents an analysis of a secondary dataset of 836 adults who presented at a UK-based domestic abuse charity between 2017 and 2022. The dataset was derived through a knowledge exchange partnership and featured both survivors and perpetrators of domestic abuse. Results: Though the logistic regression model was more proficient at predicting those more likely to not engage in self-harm, than those more likely to engage in self-harm, self-harm was predicted by witnessing domestic abuse as a child, reporting aggressive behavior, and previously or currently abusing alcohol, with the presence of aggressive behavior being the strongest predictor. Opposing existing literature, neither abusing drugs nor (not) having children contributed significantly to this model. Conclusions: Though results of this study require replication and extension, they indicate a series of variables which might serve as internationally relevant key indicators of risk for self-harm in survivors and perpetrators of domestic abuse. Charities which serve this population might seek to develop further educational material and interventions to rapidly deliver to service users who indicate risk during initial and subsequent consultations.

The present study explored links between male Dark Tetrad personality traits (psychopathy, Machiavellianism, narcissism, sadism) and preferences for using outdoor and indoor female sex worker services. We also investigated the mediating effects of perceiving sex workers as deviant and as victims. Heterosexual males (N ¼ 347) were recruited to take part in an online survey investigating personality and attitudes towards female sex workers. Path analyses revealed that psychopathy and sadism positively predicted preferences for outdoor but not indoor female sex services. Sex worker choice mediated positive links between narcissism and outdoor female sex worker preferences. Compared to indoor, outdoor sex services are associated with increased aggression and violence. Our findings highlight the importance of considering narcissism and particularly psychopathy and sadism when investigating individual male preferences for outdoor sex services that are being offered by particularly vulnerable women.

Abstract. The Dark Triad personality traits have previously been linked with dysfunctional types of procrastination (i.e., delaying certain tasks). From an evolutionary perspective, procrastination is recognized for facilitating a fast life history strategy. The present study investigated links between active and passive procrastination and the extended Dark Tetrad personality traits (psychopathy, Machiavellianism, narcissism, sadism). Participants ( N = 357) were invited via Prolific data collection platform and Survey Circle research sites to participate in an online survey exploring personality and procrastination. Path analyses revealed that all Dark Tetrad traits positively predicted several aspects of active procrastination only. Narcissism emerged as the only negative predictor of passive procrastination. Rather than linking these traits with dysfunctional procrastination types only, our results highlight the importance of considering the Dark Tetrad about functional forms of procrastination, which may be more beneficial for facilitating a fast life history strategy.
