Confirmatory factor analysis techniques were applied to test how competing models (unifactorial, bifactorial, and trifactorial) could be used to explain the structure of schizotypal disorder as defined in DSM-III-R and DSM-IV. Subjects were 538 nonpsychotic psychiatric outpatients and a replication sample of 225 nonpsychiatric patients and control subjects, interviewed by clinicians using the Structured Interview for DSM-III-R Personality Disorders. The study found that the best-fit solution encompassed three factors: cognitive-perceptual, interpersonal, and oddness. Future studies may benefit from considering schizotypal personality disorder as composed of three factors that may indicate the existence of three underlying (dys)functional systems.
验证性因素分析技术被用于检验竞争模型（单因素、双因素和三因素模型）如何用于解释《精神疾病诊断与统计手册第三版修订本》（DSM-III-R）和《精神疾病诊断与统计手册第四版》（DSM-IV）中所定义的分裂型障碍的结构。研究对象为538名非精神病性精神科门诊患者以及225名非精神科患者和对照对象的重复样本，由临床医生使用《精神疾病诊断与统计手册第三版修订本》人格障碍结构化访谈进行访谈。研究发现，最佳拟合解决方案包含三个因素：认知-感知、人际和怪异。未来的研究可能会受益于将分裂型人格障碍视为由三个因素组成，这可能表明存在三个潜在的（功能）失调系统。
