Which of the following best describes a symptom of Schizotypal Personality Disorder?

A symptom of Schizotypal Personality Disorder is indeed characterized by difficulty in developing relationships. Individuals with this disorder typically exhibit social and interpersonal deficits that often lead to acute discomfort in close relationships, as well as a pattern of social anxiety. This difficulty is informed by their eccentric behavior and cognitive or perceptual distortions, which can contribute further to social isolation and an inability to form meaningful connections with others.

The other options do not accurately reflect the hallmark features of Schizotypal Personality Disorder. Unstable self-image and a need for admiration are more closely associated with Borderline Personality Disorder and Narcissistic Personality Disorder, respectively. Grandiose fantasies typically relate to Narcissistic Personality Disorder, as they involve an inflated sense of self-importance and a preoccupation with success and power. In contrast, individuals with Schizotypal Personality Disorder may experience odd beliefs or magical thinking rather than grandiosity.
