To evaluate the relationships of symptoms of catatonic schizophrenia to 77 symptoms relevant for diagnosing schizophrenia and to socioanamnestic variables.
Data from a sample of 112 Canadian patients diagnosed with schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) were evaluated via phi correlation coefficients.
Forty-five (40.2%) of our 112 patients had catatonic symptoms, either at the time of this study or in the past. However, only weak correlations (phi < 0.31) to other symptoms relevant for diagnosing schizophrenia were found, and no significant correlations to socioanamnestic variables were found.
Symptoms of catatonia appear to be independent of the key symptoms of schizophrenia.
评估紧张型精神分裂症的症状与77种与精神分裂症诊断相关的症状以及社会记忆变量之间的关系。
通过phi相关系数对112名根据《精神疾病诊断与统计手册》（DSM-III）诊断为精神分裂症的加拿大患者样本数据进行评估。
在我们的112名患者中，有45名（40.2%）在本研究时或过去有紧张症状。然而，仅发现与其他精神分裂症诊断相关症状的弱相关性（phi<0.31），且未发现与社会记忆变量的显著相关性。
紧张症症状似乎独立于精神分裂症的关键症状。
