Within the framework of the vulnerability-stress model of schizophrenia, it is assumed that there is a specific relationship between the factors "expressed emotion" in the family of the patients and "psychophysological activation" of the patients. High expressed emotion would go together with a rise in psychophysiological activation. The aim of this study was to test whether psychophysiological correlates of an emotional family atmosphere could be found in the case of 2 schizophrenic patients in remission and their relatives (parents). The patients and their respective relatives were examined psychophysiologically during a baseline condition (alone), non-verbal interaction, and a discussion of relevant conflict areas. Among other things, three electrodermal parameters were recorded as autonomous measures of activation: SCL, number and amplitudes of nsSCs. The Camberwell Family Interview was used for assignment of EE. In addition, psyhopathological symptoms, reciprocal behavior assessment and agreement in various areas of life with self-assessment scales were recorded for patients and relatives. Despite the effectiveness of the experimental conditions, the EE categories were not reflected in any of the recorded measurements on the psychophysiological level. However, the EE categories were clearly reflected in the psychological parameters. HEE relatives proved to be less in agreement with others within the family, and they tended to be psychopathologically more conspicuous. The mutual behavior assessment for HEE couples was more negative than for LEE couples. The overlapping effects that could be a possible explanation of the psychophysiological findings and the results of the psychological correlates are discussed. Possibilities for improvement and further research strategies are suggested.
在精神分裂症的易感性-应激模型框架内，假定患者家庭中的“情感表达”因素与患者的“心理生理激活”之间存在特定关系。高情感表达会伴随着心理生理激活的增加。本研究的目的是检验在2名处于缓解期的精神分裂症患者及其亲属（父母）中，是否能发现情感家庭氛围的心理生理相关因素。在基线状态（独处）、非言语互动以及相关冲突领域的讨论期间，对患者及其各自的亲属进行了心理生理检查。除其他外，记录了三个皮肤电参数作为激活的自主测量指标：皮肤电导率（SCL）、非特异性皮肤电反应（nsSCs）的数量和幅度。使用坎伯韦尔家庭访谈来评定情感表达。此外，还记录了患者和亲属的精神病理症状、相互行为评估以及在生活各个领域与自我评估量表的一致性。尽管实验条件有效，但在心理生理水平上记录的任何测量中都未反映出情感表达类别。然而，情感表达类别在心理参数中得到了明显反映。高情感表达的亲属在家庭中与他人的一致性较低，并且在精神病理方面往往更明显。高情感表达夫妇的相互行为评估比低情感表达夫妇更消极。讨论了可能解释心理生理结果和心理相关结果的重叠效应。提出了改进的可能性和进一步的研究策略。
