Which personality disorder is characterized by pervasive social detachment and restricted emotional expression?

The personality disorder characterized by pervasive social detachment and restricted emotional expression is Schizoid Personality Disorder. Individuals with this disorder typically exhibit a consistent preference for solitary activities and demonstrate limited interest in forming personal relationships. They often appear emotionally cold or indifferent, which can lead to a deep sense of isolation.

This condition is distinct from other personality disorders listed. For instance, those with Paranoid Personality Disorder often exhibit a pervasive distrust and suspicion of others, leading to a different social interaction style. Narcissistic Personality Disorder is marked by grandiosity and a need for admiration, which contrasts with the detachment seen in Schizoid Personality Disorder. Borderline Personality Disorder involves intense emotional experiences and unstable relationships, highlighting emotional expression rather than restricting it.

Overall, Schizoid Personality Disorder accurately describes individuals who maintain a considerable emotional distance and prefer to navigate life outside of intimate or social engagements.
