50-80%的病例即使在治疗后，惊恐障碍症状仍持续存在，导致残疾和生活不满的经历。以前的研究主要集中在焦虑敏感性（AS）及其维度作为恐慌症的症状;然而，最近的研究表明，不容忍的不确定性（IU）的倾向，一个人认为一个负面事件发生的可能性作为威胁，无论其发生的实际概率可能也发挥了关键作用。本研究旨在评估IU维度（即前瞻性IU和抑制性IU）与惊恐障碍相关的恐惧和回避症状之间的特定关系。参与者包括122名社区成员（81%为女性），他们至少有一次恐慌发作史，参加了一项更大的恐惧研究。参与者完成了AS，IU和恐慌症症状的测量。相关和回归分析支持AS，抑制IU和惊恐障碍症状之间的显着和实质性的关系。抑制性IU在与惊恐障碍相关的回避症状中比AS的身体感觉维度的恐惧占相对更多的方差。因此，进一步研究IU在惊恐障碍症状中的作用似乎是必要的。全面的结果，影响和未来的研究方向进行了讨论。
Panic disorder symptoms are persistent for 50-80% of cases even after treatment, resulting in experiences of disability and dissatisfaction in life. Previous research has focused on anxiety sensitivity (AS) and its dimensions as contributing to symptoms of panic disorder; however, recent research has suggested that intolerance of uncertainty (IU)the tendency for a person to consider the possibility of a negative event occurring as threatening, irrespective of the actual probability of its occurrencemay also play a critical role. The current study was designed to assess the specific relationships between dimensions of IU (i.e. prospective IU and inhibitory IU) and the fear and avoidance symptoms associated with panic disorder. Participants included 122 community members (81% women) with a history of at least one panic attack who participated in a larger study on fear. Participants completed measures of AS, IU, and panic disorder symptoms. Correlation and regression analyses supported a significant and substantial relationship between AS, inhibitory IU, and panic disorder symptoms. Inhibitory IU accounted for relatively more variance in avoidance symptoms related to panic disorder than did the fears of physical sensations dimension of AS. As such, further investigation of the role of IU in panic disorder symptoms appears warranted. Comprehensive results, implications, and directions for future research are discussed.
