The authors examined the symptoms of 35 patients with schizotypal personality disorder. In contrast to the suggestion, based on studies of nonclinical, familial samples, that patients with schizotypal disorder are best characterized by the negative symptoms of social isolation and impaired functioning, they found that the positive symptoms of odd communication, ideas of reference, magical thinking, and illusions were equally valid discriminators of their clinically based group of patients. The findings argue against the idea that schizotypal personality disorder be redefined in the revision of DSM-III (DSM-III-R) to emphasize negative symptoms and suggest that clinical samples of schizotypal patients may differ from familial samples.
作者们研究了35例分裂型人格障碍患者的症状。基于对非临床、家族样本的研究，有人认为分裂型障碍患者的最佳特征是社交孤立和功能受损等阴性症状，但作者们发现，古怪言语、牵连观念、奇幻思维和幻觉等阳性症状同样也是他们基于临床的患者群体的有效鉴别指标。这些发现反驳了在《精神疾病诊断与统计手册》第三版修订版（DSM-III-R）中重新定义分裂型人格障碍以强调阴性症状的观点，并表明分裂型患者的临床样本可能与家族样本有所不同。
