Which of the following is a symptom of Schizoid Personality Disorder?

In Schizoid Personality Disorder, individuals exhibit a pervasive pattern of detachment from social relationships and a restricted range of emotional expression in interpersonal settings. This limited emotional expression is a central feature of the disorder, making it difficult for these individuals to engage in typical social and emotional exchanges. They often seem indifferent to others, may appear aloof or emotionally cold, and generally show little interest in forming close attachments.

The other options do not align with the characteristics of Schizoid Personality Disorder. A desire for close relationships contradicts the core features of the disorder, as individuals with Schizoid Personality Disorder typically prefer solitary activities and express little interest in social interactions. High levels of paranoia are more characteristic of paranoid personality disorder or schizophrenia rather than Schizoid Personality Disorder. Frequent mood swings are indicative of mood disorders or borderline personality disorder, which are distinct from the stable and flat affect often observed in schizoid individuals.
