颈部残疾指数（NDI）和诺思威克公园颈部疼痛问卷（NPQ）的开发是为了衡量颈部疼痛的自我感知残疾，包括可能由挥鞭样损伤引起的。然而，很少有数据专门关于他们的有效性挥鞭相关疾病（WAD）。本研究的目的是评估NDI和NPQ作为WAD结局指标的有效性，方法是将其与患者偏好问卷（问题引出技术（PET））进行比较，该问卷可识别对患者个体最重要的问题。一项横断面研究的71例患者不同的严重程度和持续时间的WAD招募从私人物理治疗的做法。所有患者完成了一个标准化的自我管理的问卷调查，其中包括人口统计学和临床细节，以及自我感知的疼痛和症状的严重程度，NDI和NPQ。由一名经过培训的面试官进行PET检查。残疾措施的结构效度进行了检查，通过确定它们之间的相关性，并通过计算皮尔森相关系数与疼痛和症状的严重程度。内容效度的NDI和NPQ进行了评估，通过比较这两个问卷的项目，PET所确定的问题。参与者的平均年龄为40.1岁（SD = 14.3），59名女性（83.1%）。大多数患者属于WAD I类（n = 23，32.1%）或II类（n = 42，59.2%）。平均NDI、NPQ和PET评分分别为40.7（SD = 17.0）、38.7（SD = 15.8）和160.2（SD = 92.0，范围6.0-509.5）。NDI与PET、NPQ与PET、NDI与NPQ之间的相关性分别为r = 0.57、0.56和0.88。PET识别出每例患者平均7.7个问题（SD = 4.2，范围1-17个问题）。最常见的问题是工资工作（52.1%），白天疲劳（50.7%），参加体育活动（47.9%），抑郁（43.7%），开车（43.7%），与朋友社交（33.8%），整夜睡觉（31.0%），沮丧（31.0%）和愤怒（28.2%）。其中只有三个问题包含在NDI（工作、驾驶和睡眠）中，只有四个问题包含在NPQ（工作、驾驶、睡眠和社交活动）中。虽然NDI和NPQ都包括一些WAD患者常见的问题，但经常发现的问题，如情感和社交项目都不存在。与PET相比，这两种仪器都不能捕捉到患者认为重要的残疾的全部范围。(C)2002年国际疼痛研究协会。由Elsevier Science B.

The Neck Disability Index (NDI) and Northwick Park Neck Pain Questionnaire (NPQ) were developed to measure self-perceived disability from neck pain, including that which may arise from whiplash injury. However, there is little data specifically concerning their validity for whiplash-associated disorders (WAD). The aim of this study was to assess the validity of the NDI and NPQ as measures of outcome in WAD by comparing them to a patient preference questionnaire, the problem elicitation technique (PET), which identifies problems that are of most importance to the individual patient. A cross-sectional study of 71 patients with varying severity and duration of WAD were recruited from a private physiotherapy practice. All patients completed a standardized self-administered questionnaire that included demographic and clinical details as well as self-perceived pain and severity of symptoms, NDI and NPQ. A trained interviewer administered the PET. Construct validity of the disability measures was examined by determining their correlation with each other and with pain and severity of symptoms by calculating Pearson's correlation coefficients. Content validity of the NDI and NPQ was assessed by comparing the items of both questionnaires to the problems identified by the PET. Participants' mean age was 40.1 years (SD = 14.3) and 59 were women (83.1%). Most patients were in WAD category I (n = 23, 32.1%), or II (n = 42, 59.2%). Mean NDI, NPQ, and PET scores were 40.7 (SD = 17.0), 38.7 (SD = 15.8), and 160.2 (SD = 92.0, range 6.0-509.5), respectively. Correlations between the NDI and PET, NPQ and PET, and NDI and NPQ were r = 0.57, 0.56 and 0.88, respectively. The PET identified an average of 7.7 problems per patient (SD = 4.2, range 1-17 problems). Problems most commonly identified were work for wages (52.1%), fatigued during the day (50.7%), participation in sports (47.9%), depression (43.7%), drive a car (43.7%), socialize with friends (33.8%), sleep through the night (31.0%), frustration (31.0%), and anger (28.2%). Only three of these problems are included in the NDI (work, driving, and sleeping) and only four are included in the NPQ (work, driving, sleeping, and social activities). While both the NDI and NPQ include some problems that are common in patients with WAD, frequently identified problems, such as emotional and social items are absent. In contrast to the PET, neither instrument captures the full spectrum of disabilities judged to be important by the patient. (C) 2002 International Association for the Study of Pain.
