目的：本研究的目的是开发并开始评估一种新的疼痛在患者生活中的中心性测量方法。设计：本研究设计为横断面调查和认知访谈。设置：本研究设置在一个学术性普通内科诊所。患者：65名患有慢性非恶性疼痛（CNMP）的成人内科患者。结果测量：我们通过征求慢性疼痛专家的反馈和对CNMP患者进行认知访谈，评估了10项疼痛中心性量表（COPS）的内容效度和清晰度。我们使用Cronbach's alpha评估内部一致性可靠性。我们通过比较COPS与慢性疼痛发病率的其他措施，包括疼痛的严重程度，抑郁，焦虑，身心健康功能，创伤后应激障碍，生活质量，和供应商assessment.Results.Health保健提供者认为COPS有很好的表面效度，评估结构效度。认知访谈显示，患者对项目的理解与预期的结构相匹配，量表测量了一个重要的概念，项目易于理解。COPS具有良好的内部一致性（α = 0.9）。它与年龄呈负相关（r =-0.29;P= 0.02），但与其他人口统计学特征无关。较高的COPS分数与较差的身体状况有关（r =-0.48;P< 0.001）和精神（r =-0.39;P= 0.002）健康功能、生活质量（r =-0.36;P= 0.004），以及供应商对稳定性的评估（r =-0.38;P= 0.004）以及更大的疼痛等级（r = 0.55;P< 0.001）和抑郁（r = 0.63;P< 0.001）。在多变量分析中，年龄、身心健康功能和抑郁与COPS.Conclusions独立相关。COPS具有良好的内部一致性和结构效度。需要进行更多的研究以进一步验证该量表。
Objective.The objective of the study was to develop and begin to evaluate a new measure of the centrality of pain in patients' lives.Design.The study was designed as a cross-sectional survey and cognitive interviews.Setting.The study was set in an academic general internal medicine clinic.Patients.Sixty-five adult internal medicine patients with chronic nonmalignant pain (CNMP) participated in the study.Outcome Measures.We assessed content validity and clarity of the 10-item Centrality of Pain Scale (COPS) by soliciting feedback from chronic pain experts and by conducting cognitive interviews with patients with CNMP. We assessed internal consistency reliability using Cronbach's alpha. We assessed construct validity by comparing the COPS with other measures of chronic pain morbidity including pain severity, depression, anxiety, physical and mental health function, posttraumatic stress disorder, quality of life, and provider assessment.Results.Health care providers felt the COPS had excellent face validity. Cognitive interviews revealed that patients' understanding of the items matched the intended construct, the scale measured an important concept, and items were easy to understand. The COPS had excellent internal consistency (alpha = 0.9). It was negatively associated with age (r = −0.29;P= 0.02), but not with other demographic characteristics. Higher COPS scores were associated with poorer physical (r = −0.48;P< 0.001) and mental (r = −0.39;P= 0.002) health function, quality of life (r = −0.36;P= 0.004), and provider assessment of stability (r = −0.38;P= 0.004) as well as with greater pain grade (r = 0.55;P< 0.001), and depression (r = 0.63;P< 0.001). In multivariate analyses, age, physical and mental health function, and depression were independently associated with COPS.Conclusions.The COPS has excellent internal consistency and construct validity. Additional studies are needed to further validate the scale.
