The purpose of this study was to determine whether the abnormal characteristics observed in relatives of schizophrenics represent variations in normal personality. Relatives (N = 340) of patients with schizophrenia, affective disorder, and medical or surgical conditions were personally interviewed about psychiatric symptoms and completed the Multidimensional Personality Questionnaire. Relatives who were themselves ill had elevated scores on some scales. Relatives of schizophrenics had normal scores on all personality scales, but relatives of affectively ill probands differed from other relatives on Well-Being and measures of Negative Emotionality. When schizophrenic probands were subtyped by symptoms, relatives of emotionally blunted schizophrenics were found to have slightly lower scores on Social Closeness than did relatives of controls. Overall, these results suggest that schizophrenia is unrelated to normal personality.
本研究的目的是确定在精神分裂症患者亲属中观察到的异常特征是否代表正常人格的变异。对患有精神分裂症、情感障碍以及患有内科或外科疾病的患者的亲属（N = 340）进行了关于精神症状的个人访谈，并完成了多维人格问卷。自身患病的亲属在某些量表上得分较高。精神分裂症患者的亲属在所有人格量表上得分正常，但情感障碍先证者的亲属在幸福感和负性情绪测量方面与其他亲属不同。当根据症状对精神分裂症先证者进行亚型分类时，发现情感迟钝型精神分裂症患者的亲属在社会亲密度方面的得分略低于对照组亲属。总体而言，这些结果表明精神分裂症与正常人格无关。
