Patients with schizophrenia are consistently rated by clinicians as having high levels of blunted vocal affect and alogia. However, objective technologies have often failed to substantiate these abnormalities. It could be the case that negative symptoms are context-dependent.
The present study examined speech elicited under conditions demonstrated to exacerbate thought disorder.
The Rorschach Test was administered to 36 outpatients with schizophrenia and 25 nonpatient controls. Replies to separate "perceptual" and "memory" phases were analyzed using validated acoustic analytic methods.
Compared to nonpatient controls, schizophrenia patients did not display abnormal speech expression on objective measure of blunted vocal affect or alogia. Moreover, clinical ratings of negative symptoms were not significantly correlated with objective measures.
These findings suggest that in patients with schizophrenia, vocal affect/alogia is generally unremarkable under ambiguous conditions. Clarifying the nature of blunted vocal affect and alogia, and how objective measures correspond to what clinicians attend to when making clinical ratings are important directions for future research.
精神分裂症患者经常被临床医生评定为存在明显的语音情感迟钝和言语贫乏。然而，客观技术往往无法证实这些异常。负性症状可能是依赖于情境的。
本研究在被证明会加重思维障碍的条件下，检查了患者的言语表达。
对 36 名精神分裂症门诊患者和 25 名非患者对照进行了罗夏测验。使用验证过的声学分析方法，对“知觉”和“记忆”两个独立阶段的反应进行了分析。
与非患者对照组相比，精神分裂症患者在语音情感迟钝或言语贫乏的客观测量上并没有表现出异常的言语表达。此外，临床负性症状评定与客观测量也没有显著相关。
这些发现表明，在精神分裂症患者中，在模棱两可的情况下，一般来说，语音情感和言语并没有明显的变化。阐明语音情感迟钝和言语贫乏的本质，以及客观测量与临床医生在进行临床评定时所关注的内容如何对应，是未来研究的重要方向。
