Self-report measures of disability are being used more frequently to assess patients' outcomes in clinical practice. This study examines the reliability, validity, and sensitivity to change of the Patient-Specific Functional Scale when applied to persons with neck dysfunction. The Patient-Specific Functional Scale and Neck Disability Index were applied at the initial visit, within 72 hours of the initial visit, and following 1-4 weeks of treatment in 31 patients with cervical dysfunction. At the time of the initial visit, the clinician made an estimate of patients' prognoses on a five-point scale. This estimate served as an priori construct for change: patients with better ratings would change more. The results demonstrate excellent reliability (R = .92) validity (r = .73-.83 compared with the Neck Disability Index, and r = .52-.64 compared with the prognosis rating), and sensitivity of change (r = .79-.83 compared with Neck Disability Index change scores, and r = .46-.53 compared with the prognosis rating). No difference was found between the Patient-Specific Functional Scale and Neck Disability Index in their ability to detect change over time. The results of this study are consistent with previous investigations which have concluded that the Patient-Specific Functional Scale is an efficient and valid measure for assessing disability and change in disability in persons with low back pain and knee dysfunction.
在临床实践中，残疾自评量表越来越频繁地用于评估患者的治疗结果。本研究探讨了特定患者功能量表应用于颈部功能障碍患者时的信度、效度及对变化的敏感性。对31例颈椎功能障碍患者在初诊时、初诊后72小时内以及治疗1 - 4周后应用特定患者功能量表和颈部残疾指数。在初诊时，临床医生用五点量表对患者的预后进行评估。该评估作为变化的先验结构：评分较高的患者变化更大。结果显示出极佳的信度（R = 0.92）、效度（与颈部残疾指数相比，r = 0.73 - 0.83；与预后评分相比，r = 0.52 - 0.64）以及对变化的敏感性（与颈部残疾指数变化分数相比，r = 0.79 - 0.83；与预后评分相比，r = 0.46 - 0.53）。特定患者功能量表和颈部残疾指数在检测随时间变化方面的能力未发现差异。本研究结果与先前的调查一致，先前的调查得出结论，特定患者功能量表是评估腰痛和膝关节功能障碍患者残疾及残疾变化的一种有效且可靠的方法。
