我们使用精神分裂型人格问卷评估了44名正常志愿者和40名精神分裂症先证者的非精神病亲生亲属的分裂型特征。亲属比对照组支持更多的认知-知觉特征；按性别分组的互动表明，男性亲属解释了这种差异。尽管在统计学上没有显著意义，但在人际关系特征上也观察到了类似的模式。因此，精神分裂症先证者的男性比女性亲属的某些分裂型特征的发生率似乎更高，至少在自我报告方面是这样。分量表分析表明，猜疑和参照观念是造成差异的主要原因，这表明来自认知-知觉因素和人际因素的偏执现象可能构成了亲属分裂类型的一个重要维度。与以前的研究不同，我们没有发现在受限制的情感或组织混乱的迹象上有任何差异。面谈和其他非自我报告技术可能最适合于评估这些特点，尽管问题仍然是，这两种方法的结合是否可能提供一些递增的歧视性力量。(C)1998 Elsevier Science B.V.保留所有权利。
We used the Schizotypal Personality Questionnaire to evaluate schizotypal traits in 44 normal volunteers and 40 non-psychotic, biological relatives of schizophrenic probands. Relatives endorsed more cognitive-perceptual traits than did controls; a group-by-sex interaction indicated that male relatives accounted for this difference. Although not statistically significant, a similar pattern was observed for interpersonal traits. Thus, elevated rates of some schizotypal traits appear to be more prominent in male than in female relatives of schizophrenic probands, at least when assessed by self-report. Subscale analysis indicated that differences were accounted for primarily by suspiciousness and ideas of reference, suggesting that paranoid-like phenomena from both the cognitive-perceptual and interpersonal factors may constitute an important dimension of schizotypy in relatives. Unlike previous studies, we did not find any differences in constricted affect or disorganization signs. Interviews and other non-self-report techniques are probably best suited for an assessment of these features, although the question remains as to whether the combination of both approaches might provide some incremental discriminatory power.
