这项研究考察了痛苦面部表情的心理测量学特性。对129名肩痛患者的不同样本进行了一系列主动和被动的活动范围测试，测试对象为患肢和非患肢。同样的测试在第二次被重复。参与者在三个自我报告量表上对每个测试引起的最大疼痛进行了评分。面部动作通过面部动作编码系统进行测量。一些面部动作区分了疼痛和非疼痛的动作；然而，眉毛下垂、眼眶收紧、提肌收缩和闭眼似乎构成了一个独特的、统一的动作。基于这些行为的疼痛表达指数证明了重测的可靠性和与疼痛自我报告的同时效度。这些发现支持核心疼痛表达具有令人满意的心理测量学特性的概念。它们也与疼痛表达的个体差异的暗示是一致的。在以前的研究中，对疼痛表达和自我报告之间关系的不同报道的原因进行了讨论。(C)2008年国际疼痛研究协会，由Elsevier B.V.出版。保留所有权利。
The present study examined psychometric properties of facial expressions of pain. A diverse sample of 129 people suffering from shoulder pain underwent a battery of active and passive range-of-motion tests to their affected and unaffected limbs. The same tests were repeated on a second occasion. Participants rated the maximum pain induced by each test on three self-report scales. Facial actions were measured with the Facial Action Coding System. Several facial actions discriminated painful from non-painful movements; however, brow-lowering, orbit tightening, levator contraction and eye closing appeared to constitute a distinct, unitary action. An index of pain expression based on these actions demonstrated test retest reliability and concurrent validity with self-reports of pain. The findings support the concept of a core pain expression with desirable psychometric properties. They are also consistent with the suggestion of individual differences in pain expressiveness. Reasons for varying reports of relations between pain expression and self-reports in previous studies are discussed.
