What is a defining characteristic of Paranoid Personality Disorder?

Paranoid Personality Disorder is primarily characterized by a pervasive pattern of distrust and suspiciousness toward others. Individuals with this disorder often believe that others are out to harm them, deceive them, or take advantage of them. This mistrust is deeply ingrained and can lead to significant difficulties in social and interpersonal relationships. The individual may constantly interpret benign remarks or actions as negative, contributing to a cycle of paranoia and social isolation.

In contrast, the other options describe characteristics associated with different types of personality disorders or behavioral patterns. Excessive emotionality is more representative of Borderline or Histrionic Personality Disorders. Detachment from social relationships is linked to Schizoid Personality Disorder, and marked impulsivity and instability are hallmark features of Borderline Personality Disorder. Thus, the defining characteristic of Paranoid Personality Disorder remains its focus on the persistent distrust and suspicion of others.
