目的：慢性背部疼痛和残疾之间的联系已经确立。尽管如此，文献也反映了评估残疾的方法不一致，因为研究交替使用自我报告测量、临床测试和电子监测。本研究的目的是对残疾测量进行多方法比较，以找出每种测量结构的异同。方法：20名慢性背痛患者参加了临床访问，完成问卷和临床测试，然后佩戴腕式电子动态监测装置5天来测量活动。结果：通过多元回归分析确定了各残疾评估的显著预测因子。结果表明，操作变量预测体力活动，认知-行为变量预测感知残疾，没有变量预测身体能力。讨论：3种不同方法测量的预测变量类型有显著差异。这表明每种类型的残疾评估所测量的结构存在差异。对于评估残疾预测因子的研究人员和在评估患者时使用残疾测量的临床医生来说，他们选择的残疾测量应该仔细地与所提出的目的相匹配。强大的理论和实践考虑支持在未来的研究和临床服务中使用电子动态监测。
Purpose: The link between chronic back pain and disability is well established. Despite this, the literature also reflects an inconsistency in methods of assessing disability, as studies interchangeably use self-report measures, clinical tests, and electronic monitoring. The purpose of this study was to conduct a multimethod comparison of disability measures to identify similarities and differences in the constructs measured by each.Method: Twenty chronic back pain patients participated in a clinic visit to complete questionnaires and clinical tests, followed by 5 days of wearing a wrist-worn electronic ambulatory monitoring device to measure activity. Results: Multiple regression analyses were conducted to identify the significant predictors of each disability assessment.Results showed that operant variables were predictive of physical activity, cognitive-behavioral variables were predictive of perceived disability, and no variables were predictive of physical ability.Discussion: The results indicate substantial differences in the types of variables that predict disability when measured through 3 different methods. This is suggestive of differences in the constructs measured by each type of disability assessment. The implications for researchers who assess predictors of disability and clinicians who use disability measures in their assessment of patients are that the measures of disability they select should be carefully matched to the proposed purposes. Strong theoretical and practical considerations support using electronic ambulatory monitoring in future research and clinical service.
