Twenty-eight anxiety patients, aged below 50 years, were diagnosed according to DSM-III-R criteria (panic disorder with and without agoraphobia, generalised anxiety disorder, and anxiety disorder not otherwise specified). The patients were characterised by high levels of state and trait anxiety and neuroticism, compared with the controls. However, there were no differences between patients and controls in electrodermal habituation rate, non-specific activity, or skin resistance level. When the patients were divided into electrodermally labile and stable subjects, significant differences were found between patients and controls in both electrodermal activity and Eysenck's personality dimensions. The labile patients were more introverted and attained higher psychoticism scores than either the stable patients or controls. Duration of anxiety symptoms removed the difference found in extroversion, but not in any other variable. The results are discussed in relation to the utility of electrodermal measurements in validation of diagnostic entities. It is concluded, that from the psychophysiological point of view, anxiety disorders may be examined within a dimensional framework.
28名年龄在50岁以下的焦虑症患者，根据《精神疾病诊断与统计手册》第三版修订版（DSM-III-R）标准进行诊断（伴有或不伴有广场恐惧症的惊恐障碍、广泛性焦虑症以及未另行规定的焦虑症）。与对照组相比，这些患者的状态焦虑、特质焦虑和神经质水平较高。然而，患者与对照组在皮肤电习惯化率、非特异性活动或皮肤电阻水平方面没有差异。当将患者分为皮肤电不稳定和稳定两组时，发现患者与对照组在皮肤电活动和艾森克人格维度上均存在显著差异。不稳定组患者比稳定组患者或对照组更内向，且精神质得分更高。焦虑症状的持续时间消除了在外向性方面发现的差异，但在其他任何变量中均未消除。讨论了皮肤电测量在诊断实体验证中的效用。得出的结论是，从心理生理学角度来看，焦虑症可以在维度框架内进行研究。
