The personality disorder that is most commonly linked to hostility is "Antisocial Personality Disorder" (ASPD). Individuals with ASPD often display a pattern of disregard for the rights and feelings of others, as well as a lack of empathy and remorse for their actions. They may have a pervasive pattern of aggression, deceitfulness, impulsivity, and a disregard for societal norms and rules.
Hostility is a prominent feature of antisocial behavior, and individuals with ASPD may engage in aggressive and hostile acts toward others without feeling guilt or remorse. They often have difficulty maintaining stable relationships and may have a history of conflict and violence in their interactions with others.
It's important to note that hostility is not exclusive to ASPD, and it can be a feature of other personality disorders or mental health conditions as well. For example, individuals with Borderline Personality Disorder (BPD) may also exhibit hostile behaviors, often stemming from intense emotional dysregulation and fear of abandonment.
It's crucial to remember that personality disorders are complex mental health conditions, and individuals with these disorders may display a wide range of behaviors and symptoms. Only a qualified mental health professional can properly diagnose and treat personality disorders and associated issues like hostility.
