As discussed in the research article "21 Facts & Statistics: BPD Violence And Relationship Abuse," BPD is highly associated with violence:
- 37% of partners of individuals diagnosed with BPD experienced either physical or psychological violence from their BPD partner
- 27% of females arrested for domestic violence perpetration meet the criteria for BPD
- 50% of female BPD patients report assault versus 26% of males
- Men with higher levels of BPD symptoms are more often found among batterers in both violent and nonviolent crimes
(See research article for full statistics and citations.)
But what about BPD causes these patterns of aggressive behavior and victimhood, both in their intimate relationships and broader social interactions?
Here are 11 factors that may contribute to this phenomenon:
As always, all graphics are 100% free to share under the CC BY-NC-SA license.
1. Emotional Instability
Individuals with BPD frequently grapple with emotional instability, a core feature of the disorder.
This instability can manifest in:
- Intense mood swings
- Heightened sensitivities
- Strong reactions to perceived slights or threats of abandonment
In the context of intimate relationships, this emotional turbulence can sometimes lead them to engage in behaviors that, to others, may seem like harassment.
A BPD individual might repeatedly call or text their partner, fearing abandonment, or may become overly accusatory due to misconstrued perceptions.
These behaviors, stemming from their emotional challenges, can inadvertently create a pattern that their partners perceive as harassing or overwhelming. 
2. Heightened Emotional Reactions
Individuals diagnosed with BPD frequently exhibit heightened emotional reactions, where their instinctive response to intense negative emotions appears as an intrinsic, almost reflexive, reaction.
This deeply ingrained pattern, possibly influenced by genetic predisposition or early life encounters, may manifest as reactive aggression or violent behavior when confronted with overwhelming negative sensations. [2, 3]
3. Passive-Aggressive Communication
Individuals with BPD often use a passive-aggressive communication style and may lack effective conflict resolution skills, leading to hostile behaviors within relationships. 
4. Interpersonal Sensitivity
Adults displaying borderline characteristics often report increased interpersonal sensitivity and distress, predisposing them to conflicts 
5. Childhood Trauma And Adult Relationships
Individuals with BPD often experience significantly higher instances of childhood maltreatment, which profoundly influences their adult intimate relationships.
For instance, BPD patients are 13 times more likely to report a history of childhood maltreatment compared to healthy participants.
Within this group:
- 48.9% reported experiences of physical neglect
- 42.5% emotional abuse
- 36.4% physical abuse
- 32.1% sexual abuse
- 25.3% emotional neglect
6. Antisocial Traits In The Male Partners
52.9% of male partners of women with BPD meet the criteria for antisocial personality disorder, as evidenced by symptoms of conduct disorder before age 15.
This predisposition is known to foster aggressive behavior, which invariably influences the dynamics of the relationship. 
This situation is further complicated by the elevated prevalence of other personality disorders among male partners in these relationships.
44% are diagnosed with a personality disorder, a rate substantially greater than the 9%-14% observed in the general population.

8. Emotional Needs And Manipulation
The feelings of unmet emotional needs can lead individuals to become vulnerable to manipulation and abuse, resulting in victimization.
Conversely, trying to satisfy these needs might drive some to exert control over others, leading them to become perpetrators. 
9. Coping Mechanisms: Victimization And Perpetration
When distressed, some BPD individuals might seek to regulate their negative emotions through victimization, seeing it as a form of validation or attention.
Conversely, others might perpetrate abuse as a way to regain control or divert their own feelings of powerlessness.
Both behaviors serve as coping mechanisms, albeit unhealthy ones, to manage overwhelming emotions. 
10. Adolescent BPD And Gender-Specific Violence
In adolescents, the expression of BPD varies between genders, potentially explaining the disparities in TDV and overall violence patterns.
Specifically, male adolescents with BPD often exhibit externalizing issues and pronounced anger, whereas female adolescents tend to show internalizing challenges alongside emotional dysregulation. 
11. Emotion Regulation And Victim Impact
Deficient emotion regulation in BPD females may trigger violent reactions from their male dating partners, leading to the increased instances of victimization. 
In summary, while some research suggests a correlation between Borderline Personality Disorder and instances of violence or abuse, it's critical to approach this complex issue with nuance and sensitivity.
Not all individuals with BPD engage in violent or abusive behavior, and many are more likely to be victims than perpetrators.
The multifaceted nature of BPD, often influenced by a range of environmental, genetic, and psychological factors, makes it unwise to generalize or stigmatize.
Understanding the intricate interplay of these factors can offer valuable insights into both the disorder and the actions of those diagnosed with it, but should never be used to stereotype or discriminate. It's crucial to remember that every individual is unique and that mental health issues like BPD are just one part of a larger, more complex human experience.
