Emotion Dysregulation as a Potential Risk Marker for Victim- Perpetrator Involvement in Intimate Partner Violence in Mental Disorders
This cross-sectional study of 128 participants suggests that impulse control difficulties, rather than broad emotion dysregulation, serve as a transdiagnostic mechanism linking mental disorders to the co-occurrence of intimate partner violence victimization and perpetration.

Intimate partner violence is a pattern of harm—physical, sexual, or psychological—inflicted by a current or former partner. While it is common in the general population, it strikes with disproportionate force against people living with mental health conditions. For decades, researchers have tried to understand why some people in these relationships only suffer abuse, why some only inflict it, and why a large number of people find themselves trapped in both roles simultaneously. This "victim-perpetrator" overlap is not just a statistical curiosity; it is a dangerous reality. People who both experience and commit violence tend to suffer more severe injuries and face more frequent violent events than those involved in only one direction.
To untangle this complexity, scientists have begun looking beyond specific medical diagnoses like depression or anxiety. Instead, they are examining transdiagnostic mechanisms—underlying psychological processes that cut across different mental illnesses. One such process is emotion dysregulation, which describes the struggle to manage intense feelings when they arise. When a person cannot soothe their distress or control their reactions, it can lead to impulsive actions. The question driving this new research is whether these struggles with emotional control are the hidden engine driving the most severe form of intimate partner violence, and if they can help explain why some people become both victims and aggressors.
A team of researchers from several German universities set out to investigate this question by studying 128 people. The group included 96 individuals diagnosed with various mental health conditions, ranging from personality disorders to depression and anxiety, as well as 32 healthy volunteers with no history of mental illness. The researchers asked everyone to look back on their lives and report any experiences of intimate partner violence, whether they had been the one hurting their partner, the one being hurt, or both. They also measured how difficult each person found it to regulate their emotions, specifically looking at their ability to control impulsive behavior when feeling distressed.
The study confirmed what previous data had suggested: people with mental health disorders reported significantly higher levels of involvement in intimate partner violence than those without a diagnosis. However, the deeper discovery lay in how the participants managed their emotions. When the researchers looked at the broad ability to regulate feelings, the results were mixed. But when they zoomed in on a specific aspect of emotional control—the difficulty in stopping impulsive actions when upset—a clear pattern emerged. This specific struggle was the strongest predictor of whether someone had ever committed violence against a partner. It was not just a general inability to handle emotions that mattered; it was the specific failure to pause and control an impulse in the heat of the moment.
The most striking finding concerned the group of people who were both victims and perpetrators. This group showed the highest levels of difficulty with impulse control compared to everyone else. While the overall score for emotional dysregulation did not distinguish between the different roles people played in these relationships, the specific struggle with impulsive behavior did. The researchers found that the link between having a mental disorder and becoming a victim-perpetrator was not direct. Instead, the mental disorder seemed to increase the difficulty with impulse control, and that specific difficulty, in turn, increased the likelihood of occupying that dual role. In other words, the mental health condition itself was not the direct cause of the violence; rather, it created a vulnerability in impulse control that drove the behavior.
The study also looked at whether biological sex played a role in these dynamics. Despite mixed findings in previous research, this team found no evidence that men and women differed in how emotion regulation affected their involvement in violence. The patterns held true regardless of gender. The researchers noted that their study was a snapshot in time, capturing lifetime experiences and current symptoms, which means they cannot say for certain which came first—the emotional struggles or the violent events. They also acknowledged that the group of people who were perpetrators only was very small, which limits some comparisons. However, the data strongly suggests that the specific inability to control impulsive behavior when distressed is a critical marker for the most severe and complex form of intimate partner violence.
These findings point toward a specific target for help. Rather than trying to treat a broad category of mental illness to prevent violence, interventions might be more effective if they focus directly on the skill of impulse control. If clinicians can help individuals learn to pause and manage their reactions when they are overwhelmed, they may be able to break the cycle that leads people into the dangerous overlap of being both a victim and an aggressor. This approach offers a way to address the root mechanism of the violence, potentially protecting people across many different types of mental health diagnoses.
