Study Design Longitudinal clinimetric study. Background Pain self-efficacy predicts poor recovery and mediates the relationship between pain and disability in patients with neck pain disorders (NPDs). The Pain Self-Efficacy Questionnaire (PSEQ) is a frequently used instrument to measure pain self-efficacy; however, its measurement properties have never been evaluated in a group of patients with NPDs. Objectives This study aimed to assess validity and responsiveness of the PSEQ in patients with NPDs. Methods Patients with NPDs (n = 161) were included. Confirmatory and exploratory factor analysis was used to assess structural validity. Twelve hypotheses on expected correlations with other instruments were formulated a priori to assess construct validity. Responsiveness was evaluated in 146 patients with NPDs who underwent multimodal rehabilitation by testing 12 hypotheses on expected effect sizes, area under the curve, and correlations with change in other instruments. Results Factor analyses showed that the PSEQ is a unidimensional instrument with moderate construct validity and responsiveness (50% to 75% of hypotheses met). Validity was consistent when analyzed separately for patients with whiplash-associated disorders and idiopathic neck pain, and responsiveness was better in patients with idiopathic neck pain. Conclusion The PSEQ is a unidimensional measure of pain self-efficacy in patients with NPDs, as found by previous studies in other populations. Nevertheless, in contrast with previous studies, its construct validity and responsiveness were found to be suboptimal in NPDs, suggesting that the content validity of the PSEQ and of the comparator instruments used in this study should be better assessed.

纵向临床计量研究。背景：疼痛自我效能预测恢复不良，并在颈痛障碍（NPD）患者的疼痛和残疾之间起中介作用。疼痛自我效能问卷（PSEQ）是一种常用的测量疼痛自我效能的工具，但它在 NPD 患者群体中的测量特性从未得到过评估。目的：本研究旨在评估 PSEQ 在 NPD 患者中的有效性和反应性。方法：纳入了 NPD 患者（n=161）。采用验证性和探索性因子分析来评估结构有效性。预先提出了 12 个关于与其他工具预期相关性的假设，以评估构念有效性。在接受多模式康复治疗的 146 名 NPD 患者中评估反应性，通过测试 12 个关于预期效应大小、曲线下面积和与其他工具变化相关性的假设。结果：因子分析显示，PSEQ 是一种具有中等构念有效性和反应性的单维工具（50%至 75%的假设得到满足）。在分析与挥鞭样损伤相关的障碍和特发性颈痛患者时，有效性是一致的，而在特发性颈痛患者中，反应性更好。结论：PSEQ 是一种在 NPD 患者中测量疼痛自我效能的多维工具，与之前在其他人群中进行的研究结果一致。然而，与之前的研究不同，它在 NPD 中的构念有效性和反应性被认为是不理想的，这表明 PSEQ 的内容有效性和本研究中使用的比较工具的内容有效性应该得到更好的评估。美国骨科运动医学杂志 2018；48（3）：204-216。2017 年 12 月 19 日在线发表。doi：10.2519/jospt.2018.7605.
