威胁性疼痛认知评价对接受应对策略效果的影响

The impact of threat cognitive appraisal of pain on the effect of acceptance coping strategy

目的:本研究探讨接受策略是否有助于提高个体的疼痛忍受能力,其效果是否会受到威胁性疼痛认知的削弱。方法:实验采用2×2的被试间设计,因素一为疼痛认知评价(威胁性认知/安全性认知),因素二为策略使用类型(接受/无策略)。101名健康被试被随机分到四个组,共接受两次受冷测试(the cold pressor task,CPT),测量指标包括疼痛忍耐时间,疼痛强度和应对策略的使用频率。结果:接受策略-安全性认知组的第二次CPT疼痛忍耐时间及疼痛忍耐值显著高于无策略-安全性认知组和无策略-威胁性认知组。但是在威胁性认知条件下,接受策略组的第二次CPT疼痛忍耐时间以及忍耐提高值低于接受策略-安全认知组。并且仅显著高于无策略-安全认知组。接受策略-威胁性认知组使用接受策略的频率显著低于接受策略-安全性认知组。结论:研究表明接受策略有助于提高疼痛忍受能力,但是威胁性疼痛认知评价削弱了接受策略在提高疼痛忍耐力和疼痛应对能力上的效果。

Objective： To investigate if the brief training of acceptance coping strategy can help to increa-se individual＇s pain coping ability and if threat cognitive appraisal of pain would impair the effect of the acceptance strategy.Method： The experiment used two by two between-subjects design.One factor was the cognitive appraisal of pain including threatening and reassurance cognitive appraisal.The other factor was strategy using including acceptance and no-training.101 participants were randomly assigned into four groups,who underwent 2 trials of the cold pressor pain induction with measurement of tolerance,pain intensity and coping strategies using.Results： The acceptance-reassurance group＇s pain tolerance in the second CPT and their pain tolerance increase value were higher than those in control group either in threat or reassurance condition.But when pain was appraised as a potential threat,the acceptance group＇s pain tolerance in the second CPT and their pain tolerance increase value were lower than the acceptance-reassurance group,and just higher than the no strategy-reassurance group.The acceptancethreat group reported less use of acceptance than the acceptance-reassurance group.Conclusion： The research implied that brief training of acceptance coping strategy increased pain tolerant ability.However,threat cognitive appraisal of pain impaired the effect of acceptance strategy on pain tolerance and coping.
