There is a range of anxiety-related constructs associated with pain and pain-related disability. Those most often examined are pain catastrophizing, pain anxiety and anxiety sensitivity. All three are conceptualized to be important in the development and maintenance of chronic pain, and are included within fear avoidance models. Surprisingly these constructs are not routinely examined together, and when they are, have been investigated in healthy individuals using experimental techniques or patients with chronic conditions. Although these constructs are also thought to be important in acute clinical pain, they tend not to been examined together in the same study. The focus of the current research was therefore to examine these three anxiety-related constructs in an acute pain setting, and examine their relative influence on both pain and pain-related functional disability. Participants were 82 patients with a hand fracture, recruited from a fracture clinic at a general hospital. They completed a battery of measures related to anxiety, pain and disability. Once controlling for injury-related variables, catastrophizing was found to predict current pain, pain-related anxiety predicted task-related pain, whereas anxiety sensitivity was (negatively) associated with disability. These findings are discussed in light of the relative role that these anxiety-related constructs have in pain and disability, as well as implications for future research.
有一系列与疼痛和疼痛相关残疾相关的焦虑相关结构。最常被检查的是疼痛灾难化、疼痛焦虑和焦虑敏感性。所有这三种都被认为是慢性疼痛发展和维持的重要因素，并包含在恐惧回避模型中。令人惊讶的是，这些结构通常不会一起检查，当一起检查时，它们是在健康个体中使用实验技术或慢性疾病患者中进行研究的。尽管这些结构也被认为在急性临床疼痛中很重要，但它们往往不会在同一研究中一起检查。因此，当前研究的重点是在急性疼痛环境中检查这三种焦虑相关结构，并检查它们对疼痛和疼痛相关功能残疾的相对影响。参与者是 82 名手部骨折患者，从一家综合医院的骨折诊所招募。他们完成了一系列与焦虑、疼痛和残疾相关的测量。一旦控制了与损伤相关的变量，灾难化被发现可以预测当前的疼痛，与任务相关的疼痛预测疼痛相关的焦虑，而焦虑敏感性与残疾呈（负）相关。这些发现是根据这些焦虑相关结构在疼痛和残疾中的相对作用以及对未来研究的影响进行讨论的。
