The purpose of the present study of people with recurrent vertigo (dizziness/dysequilibrium) was (a) to determine whether negative perceptions of symptoms contribute to handicap, and (b) to examine the physical and psychological factors predicting handicap over a seven-month period. Questionnaires assessing symptoms, anxiety and depression, handicap, and beliefs about the potential consequences of vertigo attacks were completed by 101 patients suffering from vestibular disorders. Three clusters of beliefs were identified: concern about loss of control, fear of serious illness, and anticipation of a severe attack. Fear of losing control and reported autonomic symptoms were significantly related to raw and residualized handicap scores, after controlling for somatization, vertigo severity, anxiety and depression. Initial levels of somatization predicted residualized handicap and emotional distress, while handicap levels predicted future emotional distress and vertigo. Negative perceptions of symptoms may contribute to an escalating cycle of vertigo, anxiety and restriction of activity.
本项针对复发性眩晕（头晕/平衡失调）患者的研究目的在于：（a）确定对症状的负面认知是否会导致功能障碍；（b）研究在七个月的时间里预测功能障碍的身体和心理因素。101名患有前庭疾病的患者完成了评估症状、焦虑和抑郁、功能障碍以及对眩晕发作潜在后果信念的问卷调查。确定了三类信念：对失去控制的担忧、对重病的恐惧以及对严重发作的预期。在控制了躯体化、眩晕严重程度、焦虑和抑郁之后，对失去控制的恐惧和报告的自主神经症状与原始及残差化功能障碍评分显著相关。初始躯体化水平可预测残差化功能障碍和情绪困扰，而功能障碍水平则可预测未来的情绪困扰和眩晕。对症状的负面认知可能会导致眩晕、焦虑和活动受限的恶性循环不断升级。
