What is a defining feature of schizoid personality disorder?

A defining feature of schizoid personality disorder is social detachment and emotional restriction. Individuals with this disorder typically exhibit a pervasive pattern of detachment from social relationships and a limited range of emotional expression. They often prefer solitary activities and may seem indifferent to both criticism and praise from others. This emotional flatness and lack of desire for closeness often lead those with schizoid personality disorder to appear aloof or disconnected from others. Their engagement in relationships is minimal, which differentiates them from other personality disorders that may involve more fear or anxiety about social interactions.

While excessive emotional expression is not characteristic of this disorder, and individuals may struggle with managing relationships, the core features of schizoid personality disorder lie in their emotional detachment and social disinterest. Paranoia in social situations is more characteristic of other disorders, such as paranoid personality disorder, rather than schizoid personality disorder.
