Personality disorder traits are associated with greater loneliness.

Recent developments in mental health research have highlighted the role of social factors in the lives of individuals with personality disorder diagnoses or traits. A growing body of literature has revealed the profound sense of disconnection and unmet social needs characterizing this group, raising questions about the impact of loneliness and perceived social support (PSS) on their path to recovery. Sarah Ikhtabi and colleagues conducted a systematic review to quantify the prevalence and severity of loneliness and PSS deficits. This research was published in BMC Psychiatry.
