The present paper examines in a group of 48 schizophrenics, whether spontaneous fluctuations (SF) in electrical skin conductance show a relationship to psychiatric symptomatology. Subjects participated in an experiment that delivered nonsignal auditory stimuli. Their clinical state was assessed by the Brief Psychiatric Rating Scale (BPRS) and the Nurses' Observation Scale for Inpatient Evaluation (NOSIE). An additional set of factors with a possible influence on SF rates was also taken into account. A stepwise regression analysis showed BPRS Activation and NOSIE Manifest Psychosis to be of significance, the BPRS subscale displaying a positive and the NOSIE subtest a negative partial correlation to SF frequency. Results are discussed with regard to their implication for experiments using tonic electrodermal measurement; they are also compared with the literature on phasic electrodermal arousal.
本文在一组48名精神分裂症患者中研究皮肤电传导的自发波动（SF）是否与精神症状学相关。受试者参与了一项给予非信号听觉刺激的实验。通过简明精神病评定量表（BPRS）和护士住院患者评定观察量表（NOSIE）评估他们的临床状态。还考虑了另一组可能影响SF率的因素。逐步回归分析表明，BPRS激活量表和NOSIE明显精神病量表具有显著性，BPRS分量表与SF频率呈正偏相关，而NOSIE子测试与SF频率呈负偏相关。讨论了这些结果对使用强直性皮肤电测量的实验的意义；还与关于相位性皮肤电觉醒的文献进行了比较。
