Abstract

OBJECTIVE

The fear-avoidance model of pain posits that a painful stimulus is interpreted through pain catastrophizing, which leads to negative downstream cognitions, emotions, and behaviors that shape the experience of pain. As dispositional mindfulness is associated with less catastrophizing and pain, some researchers have suggested incorporating mindfulness into the fear-avoidance model. Across two studies, we empirically tested dispositional mindfulness as a stand-alone component within the fear-avoidance model of pain.

METHODS

Two independent, online cross-sectional surveys (Ns = 362 and 580 U.S. adults) were conducted. Participants completed validated assessments of mindfulness, pain catastrophizing, fear of pain, pain vigilance, depression, pain intensity, and pain sensitivity. Using structural equation modeling, we tested the inclusion of dispositional mindfulness in the fear-avoidance model of pain. We proposed that greater mindfulness would be associated with less pain catastrophizing, which in turn would be associated with less fear of pain, leading to less depression, and then ultimately less pain intensity and pain sensitivity.

RESULTS

Across both studies, the fear-avoidance model of pain did not fit the data well, with or without mindfulness included. We found that a simplified model fit the data best (Study 1: χ2/df = 1.83; CFI = .981; RMSEA = .049, 90% CI [0.019, 0.076]; SRMR = 0.031; Study 2: χ2/df = 2.23; CFI = .976; RMSEA = .046, 90% CI [0.026, 0.067]; SRMR = .031), such that greater mindfulness was significantly associated with less pain catastrophizing and, in turn, lower levels of pain intensity and pain sensitivity.

CONCLUSION

Our findings suggest that a simplified model, compared to the traditional fear-avoidance model, may partly explain the experience of pain among individuals without chronic pain. Future work should examine the temporal associations among these variables to inform the employment of future empirically supported interventions for pain management.

摘要

目的

疼痛的恐惧-回避模型认为,疼痛刺激是通过疼痛灾难化来解释的,这导致了负面的下游认知、情绪和行为,从而塑造了疼痛的体验。由于特质正念与较少的灾难化和疼痛有关,一些研究人员建议将正念纳入恐惧-回避疼痛模型。通过两项研究,我们实证检验了特质正念作为疼痛恐惧-回避模型中的一个独立组成部分。

方法

进行了两项独立的在线横断面调查(N=362 和 580 名美国成年人)。参与者完成了正念、疼痛灾难化、对疼痛的恐惧、疼痛警觉、抑郁、疼痛强度和疼痛敏感性的验证性评估。使用结构方程模型,我们检验了特质正念在疼痛恐惧-回避模型中的纳入。我们假设,更高的正念与更少的疼痛灾难化有关,而疼痛灾难化反过来又与更少的对疼痛的恐惧有关,从而导致更少的抑郁,最终导致更少的疼痛强度和疼痛敏感性。

结果

在两项研究中,无论是否包含正念,疼痛的恐惧-回避模型都不能很好地拟合数据。我们发现,一个简化的模型最能拟合数据(研究 1:χ2/df=1.83;CFI=.981;RMSEA=.049,90%CI[0.019,0.076];SRMR=0.031;研究 2:χ2/df=2.23;CFI=.976;RMSEA=.046,90%CI[0.026,0.067];SRMR=0.031),即更高的正念与更少的疼痛灾难化显著相关,进而与更低的疼痛强度和疼痛敏感性相关。

结论

我们的发现表明,与传统的恐惧-回避模型相比,一个简化的模型可能部分解释了无慢性疼痛个体的疼痛体验。未来的工作应该检查这些变量之间的时间关联,以为疼痛管理的未来经验支持的干预措施提供信息。
