Problem: A 34-year-old male is referred for therapy by his sister, who describes him as "always having been a loner with strange ideas." During the assessment, the patient wears a heavy winter coat in the middle of summer and speaks at length about his belief that he can influence the weather through specific "mental vibrations." He reports feeling extremely anxious in social settings, not because of a fear of judgment, but because of a paranoid sense that others have "dark auras." Importantly, he has never experienced a formal auditory hallucination, nor has he ever met the criteria for a manic or depressive episode. Which of the following clinical features most definitively distinguishes this patient's diagnosis of Schizotypal Personality Disorder from Schizophrenia? The presence of ideas of reference and magical thinking that influence behavior. The patient's report of chronic social anxiety and a lack of close confidants. The absence of persistent, culturally abnormal delusions and frank hallucinations. The presence of eccentricities in dress and speech that result in social "oddness." Need Assignment Help?
