Which cluster of personality disorders is characterized by pervasive distrust and suspiciousness of others?

The cluster of personality disorders that is characterized by pervasive distrust and suspiciousness of others is designated as Cluster A. This cluster includes paranoid personality disorder, which specifically embodies these traits of distrust and suspicion. Individuals with paranoid personality disorder often have a belief that others have malevolent intentions, leading to a pervasive pattern of distrust that affects their relationships and functioning in society.

In contrast, Cluster B encompasses dramatic, emotional, or erratic disorders such as borderline personality disorder and antisocial personality disorder, which are characterized by difficulties in emotion regulation and interpersonal relationships, rather than a fundamental distrust of others. Cluster C includes anxious and fearful disorders, such as avoidant personality disorder, which focuses on anxiety and avoidance rather than suspicion. Cluster D is not a recognized classification in personality disorder typologies. Understanding these distinctions helps in identifying and categorizing personality disorders effectively and highlights the specific nature of disorders within each cluster.
