INTRODUCTION: A number of variables reflecting attentional and emotional mechanisms of processing pain-related information have recently attracted interest, ie, fear of pain, pain catastrophizing, hypervigilance and attentional bias to pain. These variables can be assessed by explicit measures based on conscious self-report, or by implicit measures assessing mainly preconscious stages of information processing such as behavioural or electrophysiological tests. Convergent validity within implicit measures was assumed to be high, as was the discriminant validity between implicit and explicit measures.METHOD: In the present study, two implicit measures (the dot-probe task for pain words and a word-processing task for pain words allowing event-related brain potential recordings) and three self-report measures (Pain Catastrophizing Scale, Pain Anxiety Symptoms Scale, and Pain Hypervigilance and Awareness Questionnaire) were administered to 27 healthy participants.RESULTS: No significant associations were found between the implicit measures, or between the event-related brain potentials of pain words and the explicit measures. A single significant positive correlation was found between the dot-probe pain bias and the Pain Anxiety Symptoms Scale.CONCLUSION: All variables appeared to be only weakly associated. The attempt to organize the field of variables targeting attentional and emotional mechanisms of processing pain-related information using concepts such as implicit and explicit measures failed as far as the present test on convergent/discriminant validity proved.

自我报告，行为和电生理措施评估疼痛相关信息处理的相互关系

引言：反映出处理疼痛相关信息的注意和情感机制的许多变量最近引起了人们的关注，即对疼痛的恐惧，疼痛的灾难性，警惕性和对疼痛的注意偏见。这些变量可以通过基于有意识的自我报告的显式测量或通过评估主要是信息处理的前知阶段（例如行为或电生理测试）的隐式测量来评估。假设隐式量度内的收敛效度较高，隐式量度与显式量度之间的判别效度也较高。方法：在本研究中，两个隐式量度（疼痛词的点探针任务和疼痛词的词处理任务）允许记录与事件相关的脑电势）和三种自我报告措施（疼痛灾难性量表，对27名健康参与者进行了疼痛焦虑症状量表和疼痛超警觉和意识问卷调查。结果：隐性措施之间，疼痛词与事件相关的脑潜能与显性措施之间均未发现显着关联。结论：疼痛焦虑症状量表与点探针疼痛偏倚之间存在单个显着的正相关。结论：所有变量似乎均呈弱相关。直到目前对收敛性/判别效度的检验证明了这一尝试，使用诸如隐性和显性度量之类的概念来组织针对处理疼痛相关信息的注意力和情感机制的变量领域的尝试失败了。结果：隐性测度之间，疼痛词与事件相关的脑电势与显式测度之间未发现显着关联。结论：疼痛焦虑症状量表与点探针疼痛偏倚之间存在单个显着的正相关。结论：所有变量似乎均呈弱相关。直到目前对收敛性/判别效度的检验证明了这一尝试，使用诸如隐性和显性度量之类的概念来组织针对处理疼痛相关信息的注意力和情感机制的变量领域的尝试失败了。结果：隐性测度之间，疼痛词与事件相关的脑电势与显式测度之间未发现显着关联。结论：疼痛焦虑症状量表与点探针疼痛偏倚之间存在单个显着的正相关。结论：所有变量似乎均呈弱相关。直到目前对收敛性/判别效度的检验证明了这一尝试，使用诸如隐性和显性度量之类的概念来组织针对处理疼痛相关信息的注意力和情感机制的变量领域的尝试失败了。结论：疼痛焦虑症状量表与点探针疼痛偏倚之间存在单个显着的正相关。结论：所有变量似乎均呈弱相关。直到目前对收敛性/判别效度的检验证明了这一尝试，使用诸如隐性和显性度量之类的概念来组织针对处理疼痛相关信息的注意力和情感机制的变量领域的尝试失败了。结论：疼痛焦虑症状量表与点探针疼痛偏倚之间存在单个显着的正相关。结论：所有变量似乎均呈弱相关。直到目前对收敛性/判别效度的检验证明了这一尝试，使用诸如隐性和显性度量之类的概念来组织针对处理疼痛相关信息的注意力和情感机制的变量领域的尝试失败了。
