Low back pain is highly prevalent, and most often, a specific causative factor cannot be identified. Therefore, for most patients, their low back pain is labeled as nonspecific. Patient education and information are recommended for all these patients. The internet is an accessible source of medical information on low back pain. Approximately 50% of patients with low back pain search the internet for health and medical advice. Patient satisfaction with education and information is important in relation to patients' levels of inclination to use web-based information and their trust in the information they find. Although patients who are satisfied with the information they retrieve use the internet as a supplementary source of information, dissatisfied patients tend to avoid using the internet. Consumers' loyalty to a product is often applied to evaluate their satisfaction. Consumers have been shown to be good ambassadors for a service when they are willing to recommend the service to a friend or colleague. When consumers are willing to recommend a service to a friend or colleague, they are also likely to be future users of the service. To the best of our knowledge, no multi-item instrument exists to specifically evaluate satisfaction with information delivered on the web for people with low back pain.
This study aims to report on the development, reliability testing, and construct validity testing of the Online Patient Satisfaction Index to measure patients' satisfaction with web-based information for low back pain.
This is a cross-sectional validation study of the Online Patient Satisfaction Index. The index was developed with experts and assessed for face validity. It was subsequently administered to 150 adults with nonspecific low back pain. Of these, 46% (70/150) were randomly assigned to participate in a reliability test using an intraclass correlation coefficient of agreement. Construct validity was evaluated by hypothesis testing based on a web app (MyBack) and Wikipedia on low back pain.
The index includes 8 items. The median score (range 0-24) based on the MyBack website was 20 (IQR 18-22), and the median score for Wikipedia was 12 (IQR 8-15). The entire score range was used. Overall, 53 participants completed a retest, of which 39 (74%) were stable in their satisfaction with the home page and were included in the analysis for reliability. Intraclass correlation coefficient of agreement was estimated to be 0.82 (95% CI 0.68-0.90). Two hypothesized correlations for construct validity were confirmed through an analysis using complete data.
The index had good face validity, excellent reliability, and good construct validity and can be used to measure satisfaction with the provision of web-based information regarding nonspecific low back pain among people willing to access the internet to obtain health information.

腰痛极为常见，且大多数情况下无法确定具体病因。因此，大多数患者的腰痛被归类为非特异性腰痛。建议为所有此类患者提供患者教育和信息。互联网是获取腰痛医学信息的便捷来源。约50%的腰痛患者会在网上搜索健康和医疗建议。患者对教育和信息的满意度对于他们使用网络信息的倾向程度以及对所获信息的信任度至关重要。虽然对所检索信息满意的患者会将互联网用作补充信息来源，但不满意的患者往往会避免使用互联网。消费者对产品的忠诚度常被用于评估他们的满意度。研究表明，当消费者愿意向朋友或同事推荐某项服务时，他们就是该服务的良好代言人。当消费者愿意向朋友或同事推荐某项服务时，他们也很可能会成为该服务的未来用户。据我们所知，目前尚无专门用于评估腰痛患者对网络提供信息的满意度的多项目工具。
本研究旨在报告在线患者满意度指数的开发、信度测试和结构效度测试情况，以衡量患者对基于网络的腰痛信息的满意度。
这是一项对在线患者满意度指数的横断面验证研究。该指数由专家共同开发并进行表面效度评估。随后，将其应用于150名患有非特异性腰痛的成年人。其中，46%（70/150）被随机分配参与使用组内相关系数一致性进行的信度测试。基于一个关于腰痛的网络应用程序（MyBack）和维基百科进行假设检验，以评估结构效度。
该指数包括8个项目。基于MyBack网站的中位数得分（范围为0 - 24）为20（四分位间距18 - 22），维基百科的中位数得分为12（四分位间距8 - 15）。使用了整个得分范围。总体而言，53名参与者完成了重测，其中39名（74%）对主页的满意度保持稳定，并被纳入信度分析。组内相关系数一致性估计为0.82（95%置信区间0.68 - 0.90）。通过对完整数据的分析，证实了结构效度的两个假设相关性。
该指数具有良好的表面效度、出色的信度和良好的结构效度，可用于衡量愿意通过互联网获取健康信息的人群对非特异性腰痛网络信息提供的满意度。
