Abstract

Chronic pain patients are often confronted with repeated failure to achieve pain relief. The aim of this study was to experimentally investigate the effects of repeated failing attempts to control pain on pain impact (pain intensity, emotional and physiological responses). Perceived control over an electrocutaneous pain stimulus was manipulated between subjects by success or failure feedback on a task by which control over pain could be acquired. In addition, success or failure at the task was manipulated without suggesting a possibility to control pain. It was hypothesized that successful control would lead to lowest pain impact, whereas failure to control pain would lead to even higher pain impact than absent control. Furthermore, it was hypothesized that failure feedback would increase pain impact when compared to success feedback. Results indicated that repeated failure to control pain increased anger and heart rate responses compared to the other conditions, but not pain intensity. It is concluded that persistent efforts to control pain in the face of failure may lead to the maintenance or exacerbation of physiological and emotional responses.

摘要

慢性疼痛患者常常面临反复无法缓解疼痛的情况。本研究的目的是通过实验调查反复尝试控制疼痛失败对疼痛影响（疼痛强度、情绪和生理反应）的作用。通过对一项可习得疼痛控制的任务给予成功或失败反馈，在受试者之间操纵对皮肤电刺激的感知控制。此外，在不暗示有控制疼痛可能性的情况下操纵任务的成功或失败。假设成功控制会导致最低的疼痛影响，而无法控制疼痛会导致比无控制更高的疼痛影响。此外，假设与成功反馈相比，失败反馈会增加疼痛影响。结果表明，与其他情况相比，反复无法控制疼痛会增加愤怒和心率反应，但不会增加疼痛强度。结论是，面对失败时持续控制疼痛的努力可能会导致生理和情绪反应的维持或加剧。
