Anxiety sensitivity (AS) is the fear of anxiety-related bodily sensations, arising from beliefs that the sensations have harmful consequences. There has been a good deal of research on the role of AS in anxiety disorders, and only recently have investigators begun to assess its role in other conditions. In a preliminary report, Asmundson and Norton (1995) found that chronic back-pain patients with high AS (n = 14), compared to those with lower AS (n = 56), reported greater pain-related fear, and tended to have greater avoidance. The present study further investigated the role of AS in pain-related fear and escape/avoidance. Patients with chronic musculoskeletal pain (N = 259) completed measures of AS, pain severity, and pain-related fear and escape/avoidance. Structural equation modeling supported the prediction that AS directly exacerbates fear of pain, even after controlling for the effects of pain severity on fear of pain. Support also was found for the prediction that AS indirectly promotes pain-related escape/avoidance via its influence on fear of pain. This indirect effect was significant even when controlling for the direct influence of pain severity on pain-related escape/avoidance. These results suggest that AS plays an important role in pain-related fear and escape/avoidance in people with chronic pain.
焦虑敏感性（AS）是指对与焦虑相关的身体感觉的恐惧，这种恐惧源于人们认为这些感觉会产生有害后果的信念。关于AS在焦虑症中的作用已经有大量研究，而直到最近研究人员才开始评估其在其他病症中的作用。在一份初步报告中，阿斯蒙森和诺顿（1995年）发现，与低AS的慢性背痛患者（n = 56）相比，高AS的慢性背痛患者（n = 14）报告的与疼痛相关的恐惧更强，且往往有更强的回避行为。本研究进一步探讨了AS在与疼痛相关的恐惧及逃避/回避行为中的作用。慢性肌肉骨骼疼痛患者（N = 259）完成了AS、疼痛严重程度以及与疼痛相关的恐惧和逃避/回避行为的测量。结构方程模型支持了这样的预测：即使在控制了疼痛严重程度对疼痛恐惧的影响之后，AS仍会直接加剧对疼痛的恐惧。研究还发现支持以下预测：AS通过对疼痛恐惧的影响间接促进与疼痛相关的逃避/回避行为。即使在控制了疼痛严重程度对与疼痛相关的逃避/回避行为的直接影响之后，这种间接效应仍然显著。这些结果表明，AS在慢性疼痛患者与疼痛相关的恐惧和逃避/回避行为中起着重要作用。
