Psychopathy checklist-youth version scores and recurring victimisation by an intimate partner in a justice-involved sample: A comparison of young men and women using longitudinal data.

Abstract

Background: People involved in the criminal justice system are at increased risk of recurring intimate partner violent (IPV) victimisation. Experience of trauma is linked to a variety of negative outcomes, including repeated experiences, so it is important to identify factors that may distinguish non-victims, single-event victims and recurring victims at an early stage as this could hold potential for intervention efforts. Research studies have identified individual-level risk factors for IPV victimisation but have not investigated psychopathy traits or sex differences.

Aims: To examine sex differences in psychopathy scores and later IPV victimisation.

Methods: Using the Pathways to Desistance study, a longitudinal study of 1354 adjudicated adolescent offenders, relationships between psychopathy checklist-youth version (PCL-YV) scores measured during the baseline wave, independent/control variables in wave 6 and self-reported IPV victimisation in wave 7 were explored using multinomial regression models.

Results: Among justice-involved young adults (average age 19), PCL-YV scores differentiated between non-victims, single-event victims and recurring victims. Higher total scores and higher ratings on the antisocial behaviours facet of psychopathy significantly increased the relative risk of recurring victimisation by an intimate partner overall, and specifically of emotional or physical intimate partner violence. For the young women but not the young men, a higher scoring on the interpersonal manipulation facet of psychopathy specifically increased the relative risk of being a recurring victim of any intimate partner violence.

Conclusions: Sex-specific differences in relationships between high PVL-YV scores and recurring IPV victimisation can be used to screen for risk of repeated trauma for justice-involved young adults, which may change a trajectory of continued involvement in the criminal justice system to a trajectory of resilience and recovery.
