It is known that children of schizophrenic parents have an increased risk for becoming schizophrenic, but it has been extremely difficult to determine what features may exist in such children before they become manifestly ill that might provide a key for identifying vulnerability to subsequent disorder. This study was carried out to determine whether certain types of egocentric perception exist in the children of psychotic parents that might represent a clue to vulnerability. Sixty parent-child pairs were investigated as part of the University of Rochester (NY) Child and Family Study, using standardized diagnostic assessment procedures in the parents and several methods for evaluating egocentric perception in their offspring. Results showed that severity of psychotic symptoms in a parent related significantly to the degree of persistent age-inappropriate spatial egocentrism in his or her child. All of several diagnostic approaches used for parent classification were about equally valid in this regard, except for hospital diagnosis of schizophrenia, which did not correlate significantly with offspring egocentricity.
众所周知，精神分裂症患者的子女患精神分裂症的风险会增加，但要确定这些子女在明显患病之前可能存在哪些特征，而这些特征可能为识别其对后续疾病的易感性提供关键线索，这极其困难。开展这项研究是为了确定精神病患者的子女中是否存在某些类型的自我中心感知，这可能是易感性的一个线索。作为纽约罗切斯特大学儿童与家庭研究的一部分，对60对亲子进行了调查，对父母使用标准化诊断评估程序，并采用多种方法评估其子女的自我中心感知。结果显示，父母精神病症状的严重程度与其子女持续存在的不符合年龄的空间自我中心程度显著相关。在这方面，用于父母分类的几种诊断方法都同样有效，但精神分裂症的医院诊断除外，它与子女的自我中心程度没有显著相关性。
