"Loneliness Linked to Personality Disorder Traits"

A systematic review published in BMC Psychiatry by Sarah Ikhtabi and colleagues found a significant correlation between personality disorders, particularly Emotionally Unstable Personality Disorder and Avoidant Personality Disorder traits, and increased levels of loneliness and deficits in perceived social support. The research also highlighted a complex association between narcissistic personality traits and loneliness/perceived social support deficits. However, the review noted a lack of longitudinal studies to definitively understand the causality of these relationships, acknowledging the low certainty of the current evidence base due to methodological limitations.
