Test reactivity is the based on the idea that experience with a test may affect performance on subsequent tests, independent of what the test purports to measure. The reactivity of a test of lift capacity was studied in a single-blind randomized clinical trial was studied in a single-blind randomized clinical trial in which subjects were assigned to one or two groups. One group received lift testing before and after a therapeutic trial, while the other group received lift testing only at the conclusion of the therapeutic trial.
To measure the reactivity of a lift capacity test over the course of treatment.
The reactivity of a test is an important criterion by which an outcome measure must be judged. Change in response to treatment is assumed to be independent of changes resulting from the evaluee's experience with the test, although this is rarely addressed.
The EPIC Lift Capacity test was administered to 55 patients with low back pain in a treatment program after they were randomized into a pre-test/post-test and a post-test only group. Additional measures were taken on a pre-test/post-test basis for all subjects.
Analyses of variance demonstrated no difference between the randomized groups after treatment. However, the pre-test/post-test group demonstrated significant improvement over the course of treatment. Other measures of outcome were similarly affected.
The reactivity of the EPIC Lift Capacity test was negligible over an 8-week treatment regimen that did not include lifting tasks.
测试反应性基于这样一种观点，即对一项测试的体验可能会影响后续测试的表现，而与该测试旨在测量的内容无关。在一项单盲随机临床试验中研究了举重能力测试的反应性，在该试验中，受试者被分为一组或两组。一组在治疗试验前后接受举重测试，而另一组仅在治疗试验结束时接受举重测试。
测量治疗过程中举重能力测试的反应性。
测试反应性是判断结果测量的一个重要标准。尽管很少有人提及，但人们认为对治疗的反应变化与被评估者对测试的体验所导致的变化无关。
在一个治疗项目中，对55名腰痛患者进行了EPIC举重能力测试，这些患者被随机分为预测试/后测试组和仅后测试组。对所有受试者在预测试/后测试基础上还进行了其他测量。
方差分析表明治疗后随机分组之间没有差异。然而，预测试/后测试组在治疗过程中表现出显著改善。其他结果测量也受到类似影响。
在一个不包括举重任务的8周治疗方案中，EPIC举重能力测试的反应性可忽略不计。
