The factor structure and normative data for the Pain Disability Index (PDI) were examined in a large (N = 1,059) sample of chronic pain patients. The results support a one-factor solution for the PDI. Analyses of normative data indicated very small effects associated with gender, age, and pain duration. Relatively larger effects were associated with compensation status, litigation status, and circumstances of pain onset. Working patients reported less disability than their nonworking counterparts, litigating patients reported more disability than nonlitigants, and patients injured at work reported higher levels of disability than those with pain origins unrelated to work. The results reflect the disability level of patients referred to a hospital-based pain management program and may be useful as a reference point when comparing disability levels of other patient groups or research samples.
在一个由大量（N = 1059）慢性疼痛患者组成的样本中，对疼痛残疾指数（PDI）的因子结构和常模数据进行了研究。结果支持PDI的单因子解决方案。对常模数据的分析表明，性别、年龄和疼痛持续时间的影响非常小。相对较大的影响与赔偿状况、诉讼状况以及疼痛发作情况有关。在职患者报告的残疾程度低于非在职患者，正在诉讼的患者报告的残疾程度高于未诉讼的患者，因工作受伤的患者报告的残疾程度高于疼痛起源与工作无关的患者。这些结果反映了转至基于医院的疼痛管理项目的患者的残疾水平，在比较其他患者群体或研究样本的残疾水平时，可能作为一个参考点。
