The relationships between depression, anxiety and positive and negative symptoms of schizophrenia were examined in a study of 95 schizophrenic patients who were receiving out-patient care. Various measures of depression and anxiety showed a pattern of interrelationships which suggested that they were measuring a general state of dysphoria rather than separate dimensions of anxiety and depression. Dysphoria was found to be more reliably related to level of positive symptomatology than to negative symptoms.
在一项针对95名接受门诊治疗的精神分裂症患者的研究中，探讨了抑郁、焦虑与精神分裂症阳性和阴性症状之间的关系。各种抑郁和焦虑测量指标呈现出一种相互关系模式，这表明它们所测量的是一种烦躁不安的总体状态，而非焦虑和抑郁的单独维度。结果发现，烦躁不安与阳性症状水平的相关性比与阴性症状的相关性更可靠。
