Although delusions of reference are one of the most common psychotic symptoms, they have been the focus of little research. The aims of the present research were, first, to determine whether it is possible to identify different kinds of referential delusions reliably and, if so, to investigate associations among them and between these delusions and other positive psychotic symptoms. Participants with a diagnosis of schizophrenia (n=57) were recruited from a volunteer register (n=26) and from inpatient psychiatric wards (n=31). They were interviewed with the Scale for the Assessment of Positive Symptoms (SAPS) except that the questions about ideas and delusions of reference were replaced with questions targeted at seven particular delusions and three content areas. Ratings were made independently by two assessors. Agreement between the assessors was high for all of the delusions of reference and other psychotic symptoms. A factor analysis of these ratings revealed two factors that represent delusions of communication and delusions of observation. Only delusions of observation were associated with hallucinations and persecutory ideation. Delusions of communication showed few significant correlations with other symptoms and therefore appear to require different explanations.
尽管关系妄想是最常见的精神病性症状之一，但一直很少有研究关注它。本研究的目的，首先是确定是否有可能可靠地识别不同类型的关系妄想，如果可以，则研究它们之间以及这些妄想与其他阳性精神病性症状之间的关联。从志愿者登记册（n = 26）和住院精神科病房（n = 31）招募了57名精神分裂症诊断患者。除了将关于观念和关系妄想的问题替换为针对七种特定妄想和三个内容领域的问题外，他们接受了阳性症状评定量表（SAPS）的访谈。由两名评估者独立进行评分。评估者之间对于所有关系妄想和其他精神病性症状的一致性都很高。对这些评分进行的因素分析揭示了两个因素，分别代表交流妄想和观察妄想。只有观察妄想与幻觉和被害观念相关。交流妄想与其他症状几乎没有显著相关性，因此似乎需要不同的解释。
