The frequently reported absence of significant correlations between patient rating scales and physiological measures has led to the belief that patients cannot reliably perceive physiological changes that are experienced under conditions of stress. To determine whether or not this conclusion is justified for patients with clinical anxiety, self-reports and psychophysiological recordings were examined and compared in 20 patients suffering from generalized anxiety disorder. No systematic correlations were found between patient ratings and physiological measures of somatic symptomatology during periods of rest or psychological stress (Stroop Test). However, parallel directional changes in the two sets of measures were observed upon exposure to stress, indicating that patients could accurately report the direction, but not the degree, of changes in physical symptoms of anxiety. These results suggest that patient reports of physical symptoms such as sweating and rapid heart rate can be useful in clinical evaluation and research settings that do not require quantitative assessment of physiological activity.
患者评定量表与生理测量指标之间经常被报道缺乏显著相关性，这使得人们认为患者无法可靠地感知在压力条件下所经历的生理变化。为了确定这一结论对于临床焦虑症患者是否合理，对20名广泛性焦虑症患者的自我报告和心理生理记录进行了检查和比较。在休息或心理应激（斯特鲁普测验）期间，患者评定与躯体症状的生理测量指标之间未发现系统性相关性。然而，在暴露于应激时，观察到两组测量指标出现了平行的方向性变化，这表明患者能够准确报告焦虑身体症状变化的方向，但无法报告其程度。这些结果表明，在不需要对生理活动进行定量评估的临床评估和研究环境中，患者关于出汗和心率加快等身体症状的报告可能是有用的。
