背景和目的：在已研究的背痛结果的可能预测因素中，心理困扰指数被发现具有很高的预后价值。本研究旨在评估新受试者样本中基于心理困扰的长期背部相关功能限制预测模型的有效性。 研究设计和环境：该研究由 860 名法语工人进行，他们在魁北克市地区的初级保健机构就非特异性背痛进行咨询。他们在基线时接受了采访，并在两年后再次接受采访。心理困扰和背部相关功能限制分别通过症状检查表 90 修订版和 RolandMorris 残疾问卷中的项目进行测量。通过将之前开发的模型强制应用于华盛顿州英语健康维护组织 (HMO) 成员样本进行分析。结果：该模型正确分类了 82% 的受试者 2 年时的功能限制状态。预测的准确性与原始研究中报告的结果相似。结论：这种反向相关功能限制的预测模型在不同的受试者样本和另一种语言中导致了相似的结果，这一事实为其有效性提供了强有力的支持。 (c) 2005 Elsevier Inc. 保留所有权利。
Background and Objective: Among the possible predictors of back pain outcomes that have been studied, indices of psychological distress have been found to have a high prognostic value. This study aimed at assessing the validity of a predictive model of long-term back-related functional limitations that is based on psychological distress, in a new sample of subjects.Study Design and Setting: The study was conducted with 860 French-speaking workers who consulted for nonspecific back pain in primary care settings of the Quebec City area. They were inter-viewed at baseline and again 2 years later. Psychological distress and back-related functional limitations were measured respectively with items drawn from the Symptom Checklist 90 Revised and the RolandMorris Disability Questionnaire. Analyses were conducted by forcing the model previously developed on a sample of English-speaking health maintenance organization (HMO) members of Washington state.Results: The model correctly classified 82% of subjects as to their functional limitation status at 2 years. The accuracy of the prediction was similar to that reported in the original study.Conclusion: The fact that this predictive model of back-related functional limitations led to similar results in a different sample of subjects and in another language brings strong support to its validity.
