Anxiety sensitivity, a fear of anxiety-related symptoms, has been associated with a heightened experience of pain, especially within women. The majority of experimental studies investigating this association have relied heavily on the cold pressor technique as a means of pain induction, limiting the generalisability of results. The aim of the current study was to extend previous research by using two types of pain stimuli (cold and heat) to determine whether the link between anxiety sensitivity and pain generalises beyond cold pressor pain. The pain experience of 125 participants in response to these stimuli was assessed using threshold and tolerance readings, as well as subjective pain ratings. Results indicated a positive association between anxiety sensitivity and subjective pain, with this association observed primarily in females. Although analysis also indicated a basic generalisability of results across pain stimuli, anxiety sensitivity effects appeared to be especially pronounced during heat stimulation. These findings suggest that those high in anxiety sensitivity may respond more negatively to specific types of pain. Possible implications along with suggestions for future research are discussed.
焦虑敏感性,即对与焦虑相关症状的恐惧,与疼痛体验加剧有关,尤其是在女性群体中。大多数研究这种关联的实验研究严重依赖冷加压技术作为诱发疼痛的手段,这限制了研究结果的普遍性。本研究的目的是通过使用两种类型的疼痛刺激(冷和热)来扩展先前的研究,以确定焦虑敏感性与疼痛之间的联系是否超出冷加压疼痛的范畴。使用阈值和耐受读数以及主观疼痛评分来评估125名参与者对这些刺激的疼痛体验。结果表明焦虑敏感性与主观疼痛之间存在正相关,这种关联主要在女性中观察到。尽管分析还表明研究结果在不同疼痛刺激中具有基本的普遍性,但焦虑敏感性效应在热刺激期间似乎尤为明显。这些发现表明,焦虑敏感性高的人可能对特定类型的疼痛反应更消极。文中还讨论了可能的影响以及对未来研究的建议。
