Pain habituation, the reduction in response to repeated painful stimuli, is a positive adaptation process, while pain sensitization is linked to chronic pain. Traits like mindfulness and extraversion affect pain processing, but their influence on pain adaptation and potential interactions remains underexplored. This study aimed to examine the relationship between trait mindfulness, extraversion, and pain adaptation, assessing their predictive value and any interaction effects.
Fifty-two healthy participants, mean age = 23.29 ± 2.052 years, completed questionnaires measuring trait mindfulness and extraversion, followed by an experimental pain stimulation to assess pain adaptation. Correlation analysis and hierarchical regression analysis were used to explore the relationships between traits and pain adaptation, and potential interaction effects.
Trait mindfulness positively correlated with extraversion, but neither trait showed a significant correlation with pain adaptation. In addition, neither trait mindfulness nor extraversion significantly predicted pain adaptation. However, a significant interaction was found between the two traits, suggesting that extraversion moderates the relationship between trait mindfulness and pain adaptation.
Trait mindfulness and extraversion are interrelated traits whose interaction affects pain habituation and the extent to which individuals with higher levels of trait mindfulness exhibit greater pain adaptation appears to depend on their levels of extraversion. These findings suggest that trait mindfulness and extraversion may act as protective factors in chronic pain development. Mindfulness-based interventions may be particularly effective for individuals with specific personality traits. This can inform further research to explore these implications for pain management.
疼痛习惯化是指对重复疼痛刺激的反应减弱，是一种积极的适应过程，而疼痛敏化与慢性疼痛有关。正念和外向性等特质会影响疼痛处理，但它们对疼痛适应的影响以及潜在的相互作用仍未得到充分研究。本研究旨在探讨特质正念、外向性与疼痛适应之间的关系，评估它们的预测价值以及任何相互作用效应。
52名健康参与者，平均年龄 = 23.29 ± 2.052岁，完成了测量特质正念和外向性的问卷，随后进行实验性疼痛刺激以评估疼痛适应。采用相关分析和层次回归分析来探讨特质与疼痛适应之间的关系以及潜在的相互作用效应。
特质正念与外向性呈正相关，但这两种特质均与疼痛适应无显著相关性。此外，特质正念和外向性均未显著预测疼痛适应。然而，发现这两种特质之间存在显著的相互作用，表明外向性调节了特质正念与疼痛适应之间的关系。
特质正念和外向性是相互关联的特质，它们的相互作用影响疼痛习惯化，特质正念水平较高的个体表现出更大疼痛适应的程度似乎取决于他们的外向性水平。这些发现表明特质正念和外向性可能在慢性疼痛发展中起到保护作用。基于正念的干预措施可能对具有特定人格特质的个体特别有效。这可以为进一步研究探索这些对疼痛管理的影响提供参考。
