Which personality disorder is characterized by a pervasive pattern of grandiosity, need for admiration, and a lack of empathy?

Choice A reason: Histrionic personality disorder is classified under Cluster B personality disorders and is characterized by a pervasive pattern of excessive emotionality and attention-seeking behavior. Key features include discomfort in situations where one is not the center of attention, theatrical and exaggerated emotional expression, seductive or provocative behavior, rapidly shifting and shallow emotional states, and use of physical appearance to draw attention. While histrionic personality disorder shares some features with narcissistic personality disorder, it is not defined by grandiosity or a global lack of empathy. The primary motivation in HPD is the need for attention, not the need for admiration combined with a sense of entitlement and superiority. Choice B reason: Schizoid personality disorder is a Cluster A disorder characterized by a pervasive pattern of detachment from social relationships and a restricted range of emotional expression in interpersonal settings. Affected individuals typically prefer solitary activities, show little desire for close relationships including family, lack interest in sexual experiences, demonstrate emotional coldness and detachment, and appear indifferent to praise or criticism. The clinical picture is one of social withdrawal and emotional aloofness, with no component of grandiosity or inflated self-image. Schizoid personality disorder is diagnostically distinct from narcissistic personality disorder in both symptomatology and underlying interpersonal dynamics. Choice C reason: Narcissistic personality disorder (NPD) is a Cluster B personality disorder formally defined in the DSM-5 by a pervasive pattern of grandiosity (either in fantasy or behavior), a persistent need for admiration, and a marked lack of empathy. Additional features include a sense of entitlement, exploitation of others, arrogance, envy of others or belief that others envy them, and preoccupation with fantasies of unlimited success, power, or beauty. The triad of grandiosity, need for admiration, and absence of empathy described in the question stem is the core diagnostic triad of NPD, making this the definitively correct answer. Choice D reason: Obsessive-compulsive personality disorder (OCPD) is a Cluster C disorder characterized by a pervasive preoccupation with orderliness, perfectionism, and mental and interpersonal control, at the expense of flexibility, openness, and efficiency. Individuals with OCPD are devoted to work and productivity, rigid and inflexible about ethics and values, unable to delegate tasks, hoarding of objects, and prone to miserly spending. OCPD is distinct from OCD in that the behaviors are ego-syntonic. There is no pattern of grandiosity, entitlement, or empathy deficit in OCPD, clearly distinguishing it from narcissistic personality disorder.
