Distinction between true negative and depressive symptoms in schizophrenia is difficult. In the present study we seek to establish the psychological profile of depression-prone schizophrenic patients. We addressed the issue by comparing the expression of psychological indices, such as the feelings of being in control of events, anxiety, mood, and the style of coping with stress in depressive and non-depressive schizophrenics. We also analyzed the strength of the association of these indices with the presence of depressive symptoms. A total of 49 patients (18 women and 31 men, aged 23-59) were enrolled into the study, consisting of a self-reported psychometric survey. We found that the prevalence of clinically significant depression in schizophrenic patients was 61%. The factors which contributed to the intensification of depressive symptoms were the external locus of control, anxiety, gloomy mood, and the emotion-oriented coping with stress. We conclude that psychological testing may discern those schizophrenic patients who would be at risk of depression development and may help separate the blurred boundaries between depressive and negative symptoms of schizophrenia.
精神分裂症中真性阴性症状与抑郁症状的区分存在困难。本研究旨在确定易患抑郁症的精神分裂症患者的心理特征。我们通过比较抑郁和非抑郁精神分裂症患者在控制感、焦虑、情绪和应对压力的方式等心理指标上的表达，来探讨这一问题。我们还分析了这些指标与抑郁症状存在的关联强度。共有 49 名患者（18 名女性和 31 名男性，年龄 23-59 岁）参与了这项自我报告的心理测量研究。我们发现，精神分裂症患者中临床显著抑郁的患病率为 61%。导致抑郁症状加重的因素包括外部控制、焦虑、忧郁情绪和情绪导向的应对压力方式。我们的结论是，心理测试可以识别出那些有发展为抑郁症风险的精神分裂症患者，并有助于区分精神分裂症阴性和抑郁症状之间模糊的界限。
