This study was performed in an effort to begin characterization of personality traits in schizophrenia. Specific concerns included personality profiles relative to normal adults, personality profile stability over time, and trait-state issues. The authors administered the NEO Personality Inventory as well as symptom ratings at two time points to 21 patients. Patients were all stabilized outpatients attending an adult continuing day treatment program and diagnosed with either schizophrenia or schizoaffective disorder. Personality profiles were determined for all patients. Compared with a normal adult sample, this sample's scores on three out of five of the personality domains assessed were not distinguishable from normal adults. Test-retest correlations were highly significant over an average 28.2-week time interval. In general, the presence of positive symptoms did not appear related to NEO-PI stability, while negative symptoms did show a relationship to the stability of personality profiles. These data suggest that personality profiles can be looked at in schizophrenia, that these profiles do appear stable over time, and that negative symptoms have a strong influence on profile stability and appear to be "trait-like."
本研究旨在开始对精神分裂症患者的人格特质进行描述。具体关注点包括相对于正常成年人的人格概况、人格概况随时间的稳定性以及特质-状态问题。作者在两个时间点对21名患者进行了NEO人格量表测试以及症状评定。这些患者均为参加成人日间持续治疗项目的病情稳定的门诊患者，被诊断为精神分裂症或分裂情感性障碍。确定了所有患者的人格概况。与正常成年人样本相比，该样本在评估的五个人格领域中的三个领域的得分与正常成年人没有差异。在平均28.2周的时间间隔内，重测相关性非常显著。总体而言，阳性症状的存在似乎与NEO-PI稳定性无关，而阴性症状确实与人格概况的稳定性有关。这些数据表明，在精神分裂症中可以研究人格概况，这些概况随时间推移似乎是稳定的，并且阴性症状对概况稳定性有很大影响，似乎具有“特质样”特征。
