Eysenck has stated that dysthymics were introverted and psychopaths were extraverted This study tested this hypothesis. The Ss were 28 male and 7 female inpatients from a state mental hospital. Twenty were diagnosed as neurotics, 15 as psychopaths. The sample was divided into extravert-introvert groups on the basis of scores on the Meyers-Briggs Type Indicator. Chi-square analysis revealed no significant differences in patient distribution by type and diagnosis. It was concluded that extraversion-introversion scores would not aid in the diagnosis of neurosis or psychopathy.
艾森克曾指出，心境恶劣障碍患者性格内向，而精神变态者性格外向。本研究对这一假设进行了检验。研究对象为一家州立精神病院的28名男性和7名女性住院患者。其中20人被诊断为神经症患者，15人被诊断为精神变态者。根据迈尔斯-布里格斯性格分类指标的得分，将样本分为外向型和内向型两组。卡方分析显示，按类型和诊断划分的患者分布没有显著差异。研究得出结论，外向-内向得分无助于神经症或精神变态的诊断。
