Questionnaires assessing symptoms, anxiety and handicap were completed by 127 vertiginous patients. Factor analysis identified four distinct symptom clusters which formed the basis for the construction of scales quantifying the number and frequency of symptoms of: (a) vertigo (of long and short duration); (b) autonomic sensations and anxiety arousal; and (c) somatization. Scores on the vertigo severity scale were significantly related to clinical diagnosis and had near-zero correlations with measures of anxiety. Vertigo severity, autonomic signs and depressed mood each independently contributed to variance in handicap, taking precedence over the relationship between handicap and trait and state anxiety. Our findings suggest that the familiar association between anxiety and vertigo may be mediated principally by autonomic symptomatology arising as a result of somatopsychic and psychosomatic processes.
127名眩晕患者完成了评估症状、焦虑和功能障碍的问卷调查。因子分析确定了四个不同的症状群，这些症状群构成了量表构建的基础，这些量表用于量化以下症状的数量和频率：(a)眩晕（长时和短时）；(b)自主神经感觉和焦虑唤醒；以及(c)躯体化。眩晕严重程度量表的得分与临床诊断显著相关，与焦虑测量指标的相关性接近零。眩晕严重程度、自主神经体征和抑郁情绪各自独立地导致了功能障碍的差异，优先于功能障碍与特质性和状态性焦虑之间的关系。我们的研究结果表明，焦虑与眩晕之间常见的关联可能主要由身心和心身过程产生的自主神经症状所介导。
