The goals of this study were to investigate the relation between sensitivity to pain and subjectively perceived intensity of pain, and to establish which psychological variables affect lesser or greater objective sensitivity to experimental pain. The study sample consisted of 74 adult women without regular pain symptoms. Experimental pain was induced by means of the Portable Electronic Dolorimeter (DEP). Intensity of induced pain was evaluated using a Visual Analogic Scale (VAS). Psychological characteristics studied were self-government, stress-coping strategies, sensitivity to anxiety and the five personality dimensions evaluated by the BFQ of Caprara, Barbaranelli and Borgogni (1995). Results revealed a positive relation between sensitivity to pain and subjective intensity of pain. An analysis of variance also revealed statistically significant differences between groups with low and high sensitivity to pain in the following variables: self-motivation, focalization in problem-solving, positive reappraisal of stressful events, energy and mental openness. The importance of the study lies in the identification of specific psychological factors for intervention in the psychological treatment of pain.
本研究的目的是调查疼痛敏感性与主观感受到的疼痛强度之间的关系,并确定哪些心理变量会影响对实验性疼痛的客观敏感性的高低。研究样本包括74名没有经常性疼痛症状的成年女性。通过便携式电子测痛仪(DEP)诱发实验性疼痛。使用视觉模拟量表(VAS)评估诱发疼痛的强度。所研究的心理特征包括自我管理、压力应对策略、焦虑敏感性以及由卡普拉拉、巴巴拉内利和博尔戈尼(1995年)的BFQ评估的五大人格维度。结果显示疼痛敏感性与疼痛主观强度之间存在正相关关系。方差分析还显示,在以下变量方面,对疼痛敏感性低和高的组之间存在统计学上的显著差异:自我激励、解决问题时的专注度、对压力事件的积极重新评估、活力和心理开放性。该研究的重要性在于确定在疼痛心理治疗中进行干预的特定心理因素。
