There is potential clinical utility in tailoring patients' pain management based on behavioural tendencies. Previous work demonstrates a link between behavioural approach/inhibition and pain experience.
To investigate the relationship of pain intensity and duration with behavioural activation and inhibition tendencies and fear-avoidance beliefs, kinesiophobia, and disability, in a sample group (n = 709) reporting chronic musculoskeletal pain.
Regression analyses assessed the predictive value of these variables on pain intensity and on pain duration. Differences in behavioural tendencies between groups reporting high and low pain intensities were examined.
Neither pain intensity nor pain duration were correlated with behavioural activation (BAS) and inhibition (BIS). Both pain intensity and duration were correlated with fear-avoidance beliefs (intensity p < .001, duration p = .005), kinesiophobia (intensity and duration both p < .001, and disability (intensity and duration both p < .001). There were significant positive relationships between pain intensity and fear-avoidance beliefs (p < .001), kinesiophobia (p = .021), and disability (p < .001), as well as positive relationships between pain duration and fear-avoidance (p = .543), kinesiophobia (p = .084) and disability (p = .002). Fear-avoidance beliefs, kinesiophobia and disability accounted for 31% of the variance in pain intensity.
Neither BIS nor BAS significantly related to, or predicted pain intensity or duration. No differences in activation and inhibition tendencies were evident between high and low pain intensity groups. This study provides further support for the inter-relationships between fear-avoidance beliefs, kinesiophobia, disability and pain duration and intensity. No explicit support for behavioural links to pain were shown, however, this may be due to the measurement instrument rather than an invalid theory.
根据行为倾向为患者量身定制疼痛管理具有潜在的临床应用价值。先前的工作表明行为倾向与疼痛体验之间存在联系。
在报告慢性肌肉骨骼疼痛的样本组（n=709）中，调查疼痛强度和持续时间与行为激活和抑制倾向以及对运动的恐惧、残疾和疼痛之间的关系。
回归分析评估了这些变量对疼痛强度和疼痛持续时间的预测价值。检验了报告高、低疼痛强度的组之间的行为倾向差异。
疼痛强度和疼痛持续时间均与行为激活（BAS）和抑制（BIS）无关。疼痛强度和疼痛持续时间均与恐惧回避信念（强度 p<0.001，持续时间 p=0.005）、运动恐惧（强度和持续时间均 p<0.001）和残疾（强度和持续时间均 p<0.001）相关。疼痛强度与恐惧回避信念（p<0.001）、运动恐惧（p=0.021）和残疾（p<0.001）呈正相关，疼痛持续时间与恐惧回避（p=0.543）、运动恐惧（p=0.084）和残疾（p=0.002）呈正相关。恐惧回避信念、运动恐惧和残疾占疼痛强度方差的 31%。
BIS 和 BAS 与疼痛强度或持续时间均无显著相关性，也无法预测疼痛强度或持续时间。高、低疼痛强度组之间的激活和抑制倾向没有差异。本研究进一步支持了恐惧回避信念、运动恐惧、残疾和疼痛持续时间与强度之间的相互关系。然而，没有明确显示行为与疼痛之间存在联系，这可能是由于测量工具而不是无效的理论。
