What characteristic is associated with Cluster A personality disorders?

Cluster A personality disorders, which include paranoid, schizoid, and schizotypal personality disorders, are primarily characterized by odd or eccentric behaviors. Individuals with these disorders often demonstrate unusual patterns of thinking, feeling, and relating to others that set them apart from societal norms. This can manifest as discomfort in social situations, odd beliefs, or peculiar ways of thinking, which reflect the eccentric nature of these disorders.

The other characteristics listed pertain to different clusters of personality disorders. For instance, behaviors described as dramatic and emotional are more aligned with Cluster B personality disorders, such as borderline and histrionic personality disorders. Outgoing and social behaviors are typically not associated with any personality disorders but rather with extroverted traits, which are more normative. Lastly, behaviors characterized by impulsivity are generally associated with Cluster B as well, particularly in disorders like borderline and antisocial personality disorders. Understanding these distinctions helps clarify the unique features of Cluster A personality disorders as fundamentally eccentric.
