Which disorder is characterized by pervasive mistrust and suspiciousness of others?

Choice A reason: Paranoid personality disorder is defined by a pervasive pattern of distrust and suspicion of others. Individuals with this disorder often interpret others’ motives as malevolent, are hypervigilant, and may hold grudges. They frequently misinterpret benign remarks or actions as threatening, which aligns directly with the description in the question. Choice B reason: Dependent personality disorder is characterized by excessive reliance on others for emotional support and decision-making. These individuals fear abandonment and struggle with self-confidence. While dependency is a hallmark, mistrust and suspicion are not features of this disorder, making it incorrect in this context. Choice C reason: Schizoid personality disorder involves detachment from social relationships and a limited range of emotional expression. Individuals with this disorder prefer solitary activities and show little interest in forming close relationships. Although they are socially withdrawn, they are not typically suspicious or mistrustful of others, so this does not match the question. Choice D reason: Histrionic personality disorder is marked by excessive emotionality and attention-seeking behavior. Individuals often display dramatic, theatrical expressions and seek approval from others. Suspiciousness and pervasive mistrust are not characteristics of this disorder, making it an incorrect choice.
